Detailed Deck Box Reviews For 2026
1. Keter Kentwood – Best Large Capacity Storage
Keter Kentwood 92 Gallon Resin Deck…
Capacity: 92 gallons
Material: Resin
Color: Brown
Features: Lockable lid,Weather resistant
The Keter Kentwood stands out as the best overall choice for most patio owners with its 92-gallon capacity that comfortably accommodates six standard seat cushions. I’ve found this size works perfectly for typical 4-piece seating sets with room to spare for throw pillows.
The resin construction delivers weather-resistant protection without the maintenance requirements of wood. You won’t need to paint or seal this box, and a quick wipe-down keeps it looking clean season after season.
Keter’s reputation for durability in outdoor storage is well-earned. This model features reinforced construction that holds up well under UV exposure without warping or cracking, which I’ve seen become issues with cheaper alternatives after one summer.
What really makes this the top pick is the balance of capacity and footprint. At 92 gallons, you get substantial storage without the box dominating your patio space like the 130-gallon models tend to do.
Who Should Buy?
Homeowners with standard patio furniture sets who need reliable storage for 4-6 seat cushions plus pillows. The 92-gallon capacity hits the sweet spot for most families.
Who Should Avoid?
Those with limited patio space or apartment balconies where the larger footprint would be impractical. Also not ideal if you need to move the box frequently.
2. Suncast 22 Gallon – Best Compact for Small Spaces
Suncast Outdoor Storage Box - 22 Gallon…
Capacity: 22 gallons
Material: Resin
Color: Stone Gray
Features: Seat function,Weatherproof
The Suncast 22-gallon deck box earns its spot as the top compact option for apartment dwellers and small patio owners. I’ve recommended this model to dozens of readers with balconies who need basic cushion storage without sacrificing their entire outdoor space.
What impresses me about this smaller box is how it maintains functionality despite the reduced size. The stone gray resin construction provides the same weather protection as larger models, and the lid stays open for easy loading.
This size works best for 2-3 standard seat cushions or a collection of throw pillows. I’ve found it’s particularly useful for apartment balconies where every square foot counts.
The seat function adds versatility, providing extra seating when you’re entertaining. With a 200-pound weight capacity on the lid, it serves double duty as both storage and seating.
Who Should Buy?
Apartment and condo residents with balconies or small patios who need basic cushion protection. Also ideal for those who only store 2-3 cushions seasonally.
Who Should Avoid?
Anyone with full patio furniture sets needing comprehensive storage. The 22-gallon capacity fills quickly with standard outdoor cushions.
3. Lifetime 130 Gallon – Best Extra Large Capacity
LIFETIME 60012 Extra Large Deck Box, 130…
Capacity: 130 gallons
Material: Resin
Color: Desert Sand
Features: Extra large space,Heavy duty
The Lifetime 130-gallon deck box dominates the competition when you need maximum storage capacity. After testing various options for large sectional sets, I’ve found this model accommodates what no other single box can handle.
With 130 gallons of interior space, this box comfortably stores 8-10 seat cushions plus multiple throw pillows. I’ve used it for full L-shaped sectionals and still had room for outdoor pillows and small accessories.
The heavy-duty resin construction feels substantial in a way that budget options don’t. Lifetime uses thicker material throughout, which I’ve noticed makes a significant difference in how the box handles temperature extremes without warping.
What sets this apart is the interior height. Many deck boxes compromise on vertical space, but the Lifetime gives you full depth that makes loading cushions with attached backs much easier.
Who Should Buy?
Owners of large sectional furniture sets or anyone needing to store 8+ cushions. Also perfect for pool owners who need cushion storage plus pool accessory space.
Who Should Avoid?
Those with limited outdoor space or anyone who needs to relocate their storage box seasonally. The large footprint and weight when loaded make this a permanent fixture.
4. Rubbermaid 120 Gallon – Most Reliable Brand Option
Rubbermaid Extra Large Resin Outdoor…
Capacity: 120 gallons
Material: Resin
Color: Multi-tone
Features: Weather resistant,Heavy duty
Rubbermaid has built a reputation on reliable outdoor storage, and their 120-gallon deck box delivers the durability the brand is known for. I’ve tracked this model’s performance over multiple seasons, and it consistently maintains its seal and structural integrity.
The resin construction features Rubbermaid’s proven formulation that resists fading and cracking better than most competitors. After three years of exposure in my test environment, this box showed minimal UV damage compared to cheaper alternatives.
What impresses me most is the lid seal. Many deck boxes develop gaps over time that let water seep in, but the Rubbermaid maintains consistent contact that keeps contents dry even during driving rain.
The 120-gallon capacity strikes a practical balance. It’s large enough for most 6-8 cushion sets but doesn’t require the massive footprint that 150+ gallon models demand.
Who Should Buy?
Shoppers who prioritize brand reliability and long-term durability. The premium construction justifies the investment for those planning to use their deck box for many years.
Who Should Avoid?
Budget-conscious buyers who can find adequate protection from lesser-known brands at a lower price point.
5. Suncast 73 Gallon – Best Waterproof Wicker Design
Suncast Outdoor Storage Box - 73 Gallon…
Capacity: 73 gallons
Material: Resin wicker
Color: Mocha Brown
Features: Lockable lid,Waterproof,Bench function
The Suncast 73-gallon resin wicker deck box combines aesthetic appeal with functional storage in a way that few competitors manage. I’ve been impressed by how the wicker texture elevates the look beyond basic plastic while maintaining weather-resistant durability.
What stands out to me is the waterproof construction. Unlike actual wicker that degrades in wet conditions, this resin version shrugs off rain and humidity while maintaining its appearance year after year.
The lockable lid adds security that many deck boxes in this size range lack. While not theft-proof, the hasp accommodates a standard padlock to keep curious kids out and provide basic protection.
At 73 gallons, this size works well for 4-5 standard seat cushions. I’ve found it’s ideal for smaller patio sets or as supplemental storage when you have a primary larger box.
Who Should Buy?
Homeowners who want storage that looks as good as it functions. The wicker design complements wicker furniture sets and adds visual appeal to any patio.
Who Should Avoid?
Those needing maximum storage capacity or anyone storing deep seat cushions, which may not fit efficiently in the 73-gallon interior.
6. Devoko 78 Gallon – Best Value Waterproof Storage
Devoko 78 Gallon Deck Box, Waterproof Resin…
Capacity: 78 gallons
Material: Resin
Color: Black
Features: Waterproof,Lockable,Bench seating
The Devoko 78-gallon deck box delivers impressive features at a price point that undercuts most competitors with similar specifications. After comparing pricing across dozens of models, I’ve found this offers the best value proposition in the mid-size category.
Waterproof construction sets this model apart from similarly priced alternatives. The resin design features tight-fitting lid channels that divert water away from the interior, keeping cushions dry through heavy storms.
What I appreciate most is the dual functionality. The reinforced lid supports up to 250 pounds, converting the box into additional seating when you’re entertaining guests outdoors.
The 78-gallon capacity hits a practical sweet spot. It stores 4-5 standard cushions comfortably while maintaining a footprint that works on most patios without dominating the space.
Who Should Buy?
Budget-conscious shoppers who don’t want to sacrifice waterproofing or seating functionality. Excellent first deck box for new patio owners.
Who Should Avoid?
Those prioritizing aesthetic appeal, as the basic resin design lacks the visual sophistication of premium options.
7. Keter Darwin 100 Gallon – Best Premium Large Capacity
Keter Darwin 100 Gallon Resin Large Deck…
Capacity: 100 gallons
Material: Resin
Color: Brown and Black
Features: Premium build,Large capacity,Cushion storage
The Keter Darwin 100-gallon deck box represents the premium end of outdoor storage with construction quality that justifies its higher price point. Having tested numerous deck boxes across price ranges, I can confirm the materials and build quality here exceed what you’ll find in budget alternatives.
The two-tone brown and black design elevates the aesthetic beyond standard utilitarian storage. Keter has incorporated wood-look texture that gives this box the appearance of high-end patio furniture rather than a basic storage container.
With 100 gallons of capacity, this model accommodates 6-7 standard seat cushions comfortably. I’ve found it particularly well-suited for deep seating sets where the larger cushions require more volume than standard sizes.
What makes this premium-worthy is the attention to detail in construction. The reinforced lid features quality hinges that operate smoothly, and the seal maintains consistent contact for superior weather protection.
Who Should Buy?
Homeowners investing in high-end patio furniture who want storage that matches their furniture quality. The premium design justifies the cost for those prioritizing aesthetics.
Who Should Avoid?
Budget shoppers or those who view deck boxes as purely functional rather than aesthetic elements of their outdoor space.
8. Keter Novel 90 Gallon – Best Sleek Modern Design
Keter Novel Plastic Deck Storage Container…
Capacity: 90 gallons
Material: Plastic
Color: Black and Gray
Features: Sleek design,Patio storage,Garden use
The Keter Novel 90-gallon deck box offers a contemporary design aesthetic that works beautifully with modern patio furniture. After testing storage solutions across various design styles, I’ve found this model particularly well-suited for homes with minimalist or contemporary outdoor decor.
The black and gray color scheme creates versatility that complements most furniture sets. Unlike brown resin boxes that can clash with modern furniture, the neutral tones here integrate seamlessly with contemporary designs.
With 90 gallons of storage capacity, this box holds 5-6 standard seat cushions with room for smaller accessories. The interior space is efficiently designed without wasted corners that reduce usable capacity.
What I appreciate is how the sleek exterior doesn’t sacrifice functionality. The lid opens smoothly and stays in place for loading, and the overall construction maintains weather resistance despite the emphasis on modern styling.
Who Should Buy?
Owners of contemporary or modern patio furniture who want storage that matches their design aesthetic. Perfect for those who value form alongside function.
Who Should Avoid?
Traditional homes where the modern styling might look out of place, or those seeking maximum weather protection over design appeal.
9. DUMOS 31 Gallon – Best Budget Lockable Option
DUMOS 31 Gallon Deck Box, Lockable Outside…
Capacity: 31 gallons
Material: Resin
Color: Rattan Black
Features: Lockable,Waterproof,Compact
The DUMOS 31-gallon deck box delivers essential storage functionality at the lowest price point I’ve found for a lockable model. For budget-conscious shoppers, this represents the minimum viable investment for protecting patio cushions from weather damage.
Despite the low price, DUMOS included a lockable hasp that many similarly sized boxes omit. This basic security feature keeps contents secure from curious children and provides some theft deterrence.
The waterproof resin construction provides adequate weather protection for occasional rain exposure. While not as robust as premium options, this box keeps cushions dry through typical summer storms when properly latched.
At 31 gallons, capacity is limited to 2-3 standard seat cushions. I’ve found this works best for apartment settings or as supplemental storage for high-use items you want to access frequently.
Who Should Buy?
Shoppers on tight budgets who need basic cushion protection. Also ideal for apartment dwellers with minimal outdoor furniture.
Who Should Avoid?
Anyone with full patio sets or families needing comprehensive storage solutions. The 31-gallon capacity fills quickly.
10. Rubbermaid 19 Gallon – Best Small Space Solution
Rubbermaid Small Resin Outdoor Storage Deck…
Capacity: 19 gallons
Material: Resin
Color: Brown
Features: Weather resistant,Compact design
The Rubbermaid 19-gallon deck box serves a specific niche as the smallest practical option for cushion storage. I’ve recommended this model to countless readers with balconies or minimal patio furniture who just need to protect 1-2 seat cushions.
What makes this viable despite the tiny capacity is Rubbermaid’s proven durability. Even at this small size and price point, the resin construction maintains the weather resistance that makes Rubbermaid a trusted name in outdoor storage.
The compact design creates versatility in placement. I’ve positioned this model on balcony railings, small porch corners, and even alongside larger storage boxes as a dedicated space for frequently used items.
The 19-gallon capacity realistically holds 1-2 standard seat cushions or a collection of throw pillows. Think of this as protective storage for your most-used cushions rather than comprehensive furniture storage.
Who Should Buy?
Apartment and condo residents with minimal outdoor furniture. Perfect for protecting 1-2 favorite cushions through rainy seasons.
Who Should Avoid?
Anyone with a full patio furniture set or family needing to store more than 2 cushions. The limited capacity makes this impractical for most households.
Understanding Patio Cushion Storage Problems
Storing patio cushions improperly leads to three expensive problems: mold growth, UV fading, and insect damage. I’ve seen replacement costs exceed $500 for ruined cushion sets that weren’t properly protected.
Mold and mildew develop quickly when cushions are stored while damp or in humid conditions. The dark, enclosed space of a poorly ventilated deck box creates ideal conditions for fungal growth that can destroy cushions in weeks.
UV radiation fades fabric colors even through some plastic storage options. Quality deck boxes use UV-resistant resins that prevent sun damage while keeping cushions dry.
Insects and rodents seek shelter in cushion stuffing during cooler months. A properly sealed deck box with tight-fitting lids prevents pests from turning your cushions into winter homes.
Pro Tip: Never store cushions while damp. Even a little moisture trapped inside leads to mold growth. Allow cushions to dry completely for 24-48 hours before storage.
How to Choose the Best Deck Box for Patio Cushions In 2026?
Sizing Guide: What Capacity Do You Need?
Choosing the right size deck box prevents the frustration of cushions that don’t fit or wasted money on excessive capacity. Use this guide based on typical cushion dimensions:
| Box Capacity | Cushion Capacity | Furniture Set Size |
|---|---|---|
| 19-31 gallons | 1-3 seat cushions | Bistro set, small balcony |
| 50-73 gallons | 4-5 seat cushions | 4-piece conversation set |
| 90-100 gallons | 6-7 seat cushions | 6-piece dining set, small sectional |
| 120-130 gallons | 8-10 seat cushions | Large sectional, full patio set |
Waterproof vs. Water-Resistant: Understanding the Difference
Waterproof deck boxes feature tight seals and channels that prevent water intrusion even in heavy rain. Water-resistant models shed light rain but may allow moisture penetration during storms or when snow melts on the lid.
For cushion storage, waterproof construction is essential. Once cushions absorb moisture, they become breeding grounds for mold that’s nearly impossible to remove.
Preventing Mold and Mildew in Stored Cushions
Mold prevention requires three elements: dry cushions before storage, ventilation, and moisture control. Even waterproof boxes can develop mold if you store damp cushions.
- Always dry cushions thoroughly before storage – at least 24-48 hours in sun
- Leave lid slightly ajar for first few days if stored slightly damp
- Add moisture absorbers like silica gel packets in humid climates
- Inspect monthly during storage season for moisture problems
- Elevate box slightly to prevent ground moisture transfer
Winter Storage Considerations
Winter storage requires additional preparation beyond basic weather protection. Freezing temperatures can make cushion materials brittle, and temperature fluctuations create condensation inside sealed containers.
Quality resin deck boxes handle winter storage well, but I recommend adding cushion covers or plastic bags for extra moisture protection in climates with heavy snowfall.
Time Saver: Label your stored cushions by location using masking tape. This makes reassembly in spring much faster when you can’t remember which cushion goes where.
Insect and Pest Protection
Deck boxes with tight-fitting lids and lockable hasps provide the best insect protection. The most common entry points are gaps around the lid and ventilation holes that some manufacturers add.
For extra protection in pest-prone areas, place cedar blocks or mothballs inside the box. Natural deterrents work well without leaving chemical residues on your cushions.

Frequently Asked Questions
What size deck box do I need for patio cushions?
For a standard 4-piece seating set with 4 seat and 4 back cushions, you need at least 73-90 gallons of storage capacity. Larger sectionals with 6-8 cushions require 100-130 gallons. Always measure your cushions and add 20% extra space for easy loading.
Are deck boxes waterproof for cushions?
Quality deck boxes are water-resistant but not completely waterproof. They protect cushions from rain and snow but may allow minimal moisture penetration during severe storms. For maximum protection, place cushions in waterproof bags inside the deck box and ensure the lid seals tightly.
Can you sit on deck boxes?
Most deck boxes support between 200-500 pounds of weight on their lids, making them functional as extra seating. However, weight capacity varies by model so always check the manufacturer’s specifications. Avoid sitting on the lid edge as this creates stress points that can crack the plastic over time.
How many cushions fit in a deck box?
A 50-gallon deck box holds approximately 4-5 standard seat cushions. A 73-gallon box accommodates 5-6 cushions. For large sectionals with 8-10 cushions, you need 120-130 gallons of capacity. Always measure your specific cushions as deep-seat cushions require significantly more space than standard sizes.
Do deck boxes keep out insects?
Deck boxes with tight-fitting lids and quality seals significantly reduce insect access but are not completely pest-proof. Spiders and small insects can enter through tiny gaps. For maximum protection in pest-prone areas, add cedar blocks or mothballs inside and ensure the lid closes completely after each use.
Will cushions get moldy in a deck box?
Cushions can develop mold in deck boxes if stored while damp or in humid conditions without ventilation. Always dry cushions thoroughly for 24-48 hours before storage. In humid climates, add moisture absorbers like silica gel packets and inspect contents monthly during the storage season.
What is the best material for deck boxes?
Resin (HDPE polypropylene) is the best material for deck boxes because it is weather-resistant, durable, and requires no maintenance. Wood looks attractive but requires annual sealing and can rot. Metal rusts over time. Resin provides the best combination of durability, weather protection, and low maintenance for cushion storage.
Can you leave deck boxes outside in winter?
Yes, resin deck boxes are designed for year-round outdoor use and can withstand winter weather. However, extreme temperature fluctuations may cause some expansion and contraction. In regions with heavy snowfall, clear snow accumulation from the lid to prevent excessive weight that could damage the hinges or lid structure.
Final Recommendations
After testing and researching deck boxes across all capacity ranges and price points, the Keter Kentwood 92-gallon model remains my top recommendation for most patio owners. It delivers the optimal balance of storage capacity, weather protection, and value for standard furniture sets.
Budget shoppers should consider the Devoko 78-gallon model, which sacrifices none of the essential waterproofing features at a significantly lower price point. For those with large sectionals or comprehensive storage needs, the Lifetime 130-gallon box provides unmatched capacity.
Remember that proper storage technique matters as much as the box you choose. Always dry cushions thoroughly before storage, add moisture control in humid climates, and inspect periodically throughout the storage season.
