Best Waterproof Outdoor Storage For Cushions: 10 Options Compared

#1 · Best Overall

1. Keter Westwood Deck Box

• Dimensions: 61"L x 28.34"W x 25.19"H
• Material: Resin
• Weight: 39.1 lb

Best for: Cushion storage with seating.

Why it ranks #1: Its listing explicitly targets furniture cushions, offers 150 gallons of lockable space, and adds seating for two adults with hydraulic-assisted opening.

A 150-gallon interior gives the Keter Westwood space for large patio cushions, while its lid also provides seating for two adults. Hydraulic pistons help with opening and closing, making access more manageable when your hands are full or you are putting cushions away after outdoor use.

The 150-gallon capacity accommodates large cushions alongside pool equipment or gardening tools, so seasonal patio items can share one storage spot. Its 61-by-28.34-inch footprint and seating for two make the box useful as an extra place to sit when the lid is closed. Hydraulic pistons assist opening and closing, while built-in handles and a lightweight build make repositioning easier. The lockable storage is a practical addition, though the available seating and storage depend on placing the box where its dimensions fit.

Skip it if you have limited space for a 61-inch box; Uthem’s 68-inch cushion bag stores cushions without a rigid deck-box footprint.

Choose the Westwood if you want substantial cushion storage that doubles as seating for two on a roomy deck or patio. Its 61-inch length and 28.34-inch width call for a suitable spot.

#2 · Best Divided Storage

2. KAMABOKO 230-Gallon Deck Box

• Dimensions: 60.8"L x 28.4"W x 29.2"H
• Material: Resin

Best for: Sorted cushion and gear storage.

Why it ranks #2: The 230-gallon resin box explicitly stores patio cushions and includes a removable divider for separating cushions from other outdoor supplies.

A removable divider lets this 230-gallon KAMABOKO box separate cushions from pool supplies or garden tools, turning a large storage space into two sorting areas. Its resin construction is paired with waterproof and UV-resistant protection, while the 60.8-inch length accommodates a substantial mix of outdoor belongings.

The 230-gallon capacity and 60.8-by-28.4-by-29.2-inch dimensions provide room for patio cushions alongside other seasonal equipment. The removable divider helps keep categories apart, so smaller supplies need not be mixed in with cushion storage. Resin construction and listed waterproof and UV-resistant protection support outdoor use, while the lockable feature provides a way to secure the contents. It is also described as easy to install and portable; its full dimensions still need to fit the deck, patio, or backyard location you choose.

Skip it if you need more than 230 gallons for a very large cushion collection; EasyUp’s 400-gallon outdoor storage box lists greater capacity.

This suits buyers who want to sort cushions from pool or garden supplies in one outdoor box. The divider and 230-gallon capacity are useful, provided its 60.8-by-28.4-inch footprint fits.

The 47.8-by-21.4-by-24.6-inch interior offers a defined space for cushions and other outdoor belongings, making it easier to gather items in one place rather than leave them around the patio. Resin construction and the product’s stated waterproof, weather-resistant positioning suit outdoor storage, while UV protection supports use in sunny spaces. The lockable feature is useful when you want a way to secure the contents. At 100 gallons, capacity is more limited than the largest boxes in this roundup.

Skip it if you need one box for a very large cushion collection; Yardgrace’s 380-gallon outdoor storage box offers substantially more capacity.

This suits buyers who want a lockable, rattan-pattern resin box for a moderate cushion collection on a deck, porch, or poolside. Consider its 100-gallon capacity against the volume of cushions and other items you plan to store.

Built-in handles help when the box needs repositioning, and the lockable feature offers a way to secure stored contents.

Skip it if you need a compact container for a small cushion set; NettyPro’s 50-by-15-by-25-inch storage bag has much smaller listed dimensions.

This is a fit for buyers consolidating a large cushion collection and assorted backyard gear in one lockable box. Check the 67.8-by-32.2-inch footprint against your available patio, deck, or garden space.

A reinforced lid and lockable feature offer added structure and a way to secure the contents, while built-in handles and a rollable feature support moving the box. Its considerable footprint requires a planned location on the patio, deck, or porch.

Skip it if you have little room for a large storage container; NettyPro’s 50-by-15-by-25-inch cushion bag takes up less listed space.

Choose this Decksplore box if you need high-capacity storage for cushions and mixed outdoor gear, with features for locking and moving it. Plan for its 67.72-by-32.2-inch footprint before placement.

Why it ranks #6: The 68-inch Oxford bag is purpose-built for chair, bench, and chaise cushions, with a waterproof claim, zipper, and carry handles.

A 68-inch length gives this Uthem bag room for many chair, bench, or chaise cushions, while its 1.4-pound weight and nylon handles make the filled bag easier to carry or move. The Oxford fabric is described as waterproof and weatherproof, making this a flexible alternative to a rigid deck box.

This bag suits buyers who want lightweight, portable protection for long patio cushions rather than a fixed deck box. Compare its 68.11-by-31.5-by-20.08-inch dimensions with the cushions and storage spot.

• Material: Iron, Polypropylene, Wood
• Weight: 17 lb

Best for: Roll-away patio storage.

Why it ranks #7: This 165-gallon box claims waterproof, UV-resistant protection and has built-in wheels, though its listed dimensions are relatively compact for its capacity.

Built-in wheels let you tilt and roll this EasyUp box between patio, garden, and poolside locations instead of lifting it. Its 165-gallon capacity provides space for cushions and other outdoor belongings, while reinforced resin is listed as waterproof and UV-resistant for changing weather and sun exposure.

Skip it if you want a cushion bag you can carry by hand; Uthem’s lightweight Oxford bag has nylon handles and weighs 1.4 pounds.

• Material: Metal
• Weight: 39.2 lb

Best for: High-capacity weather-resistant storage.

Why it ranks #8: The 400-gallon resin storage box claims water and fade resistance, but its listed dimensions and metal material entry warrant checking before purchase.

A listed 400-gallon capacity gives this EasyUp box room for an extensive cushion collection and other outdoor belongings.

9. EFU 150-Gallon Storage Box

• Dimensions: 21"L x 21.61"W x 46"H
• Material: Polypropylene

Best for: Dust-conscious resin storage.

Why it ranks #9: It offers 150 gallons and lists weathertight and dustproof features, but its description focuses on toys and tools rather than cushions.

Airtight and dustproof features distinguish this 150-gallon EFU storage box for buyers who want to keep stored items enclosed. Its polypropylene body is also described as waterproof and scratch-resistant, while the listed gas struts and wheels add practical help with opening and moving the box.

The 150-gallon capacity offers room for outdoor items, including furniture and toys, and can help gather cushions in a single storage location.

The listed dimensions are 21 by 21.61 by 46 inches, so check how that footprint and shape work for your intended cushion arrangement and available space.

Skip it if you need a wide, low box for bulky cushions; Keter Westwood’s 61-inch length and 28.34-inch width give a broader listed footprint.

Choose this EFU box if enclosed, dust-conscious storage and the listed gas struts and wheels suit your routine. Its stated 21-by-21.61-by-46-inch dimensions are a key fit consideration for cushions.

• Material: Polyester

Best for: Compact, water-resistant cushion bag.

Why it ranks #10: Its 50-by-15-by-25-inch bag is designed for chair and bench cushions, but the key feature emphasizes water resistance rather than dependable waterproofing.

A 50-by-15-by-25-inch shape gives this NettyPro bag a defined fit for smaller chair, bench, or chaise cushions, and its dual zippers create a wide opening for loading. The 600D polyester has a PVC coating and taped seams, with zipper tape intended to help keep rain from entering.

The stated maximum cushion dimensions of 50 by 15 by 25 inches help buyers assess whether their cushions can be stored together. Dual zippers provide a wide opening for loading and access, while zipper tape is intended to prevent rain entering through the zipper. The 600D polyester’s PVC coating and taped seams support its water-resistant construction. At 50 pounds load capacity, this bag has a defined limit for what it holds, so it best suits appropriately sized cushions rather than oversized patio sets.

Skip it if your cushions exceed 50 by 15 by 25 inches or the 50-pound load limit; Uthem’s 68-inch cushion bag offers a longer listed size.

Pick this bag for a compact cushion set that fits its 50-by-15-by-25-inch dimensions and 50-pound load limit. The taped seams and zipper design suit buyers seeking water-resistant soft storage.
