The best deck box for your cushions is the smallest one that fits the actual stack and works where you will open it. For this shortlist, that means comparing the usable interior and the patio footprint before giving much weight to the advertised gallon capacity.
We compared three exact models using manufacturer dimensions and the corresponding Amazon listings, without conducting hands-on storage or weather tests. This article contains affiliate links, and we may earn a commission if you buy through them.
Use the shortlist around the shape of your cushions
Consider the Keter Westwood when your stack needs the greatest interior depth and length among these three choices. Consider the Keter Kentwood when a narrower exterior suits a covered patio edge and your cushions fit its shallower interior.
The Suncast DBW9200 sits between those two in documented interior depth and offers a wicker-textured appearance. None is an automatic winner for every furniture set, and none becomes a waterproof storage guarantee simply by appearing on a patio shopping list.
Measure your dry cushions in the arrangement you intend to store, then compare all three dimensions with the figures below. Leave the opening, hinge area, handling room, and permitted storage conditions as separate checks before you order.
Compare the documented dimensions
The table uses the exact manufacturers’ published inch measurements, with each set ordered width × depth × height. This avoids mixing exterior footprints, interior cavities, and slightly rounded marketplace measurements into one comparison.
| Exact model | Nominal capacity | Interior W × D × H | Exterior W × D × H |
|---|---|---|---|
| Keter Westwood, brown, part 231666 | 150 gallons | 56 × 24.6 × 22.8 in. | 61 × 28.5 × 25.35 in. |
| Keter Kentwood, brown, part 249623 | 92 gallons | 49.6 × 20.4 × 22.8 in. | 50.3 × 21 × 23.2 in. |
| Suncast DBW9200, Java | 99 gallons | 47.5 × 22.25 × 22.5 in. | 50 × 25.5 × 25.5 in. |
Your first decision is whether the stack has a plausible place within the documented cavity, not whether the largest number feels reassuring. A long, narrow collection can produce a different answer from a deep stack of square lounge cushions.
Keter Westwood 150 Gallon: For the deeper, bulkier stack
The brown Westwood part 231666 has the largest documented interior in this comparison, and Keter lists piston assistance for its lid. The resin construction has a wood-look texture, with a padlock provision but no included padlock.
That makes it worth examining when the cushion depth rules out the two smaller interiors before you even consider the rest of the stack. The larger exterior is also the tradeoff: your patio needs to accommodate the box, its documented lid operation, and the space where you stand to handle the contents.
Imagine a set you use in two stages, with a pair of seat cushions for morning coffee and all the backs and pillows for an evening. Sketch how those items would sit so the first pair can be retrieved without emptying the rest onto the paving.
Do not treat the assisted lid as permission to ignore its operating instructions or pack into the mechanism’s space. The useful feature is one you can operate as documented with the contents arranged normally.
Keter’s exact Westwood page documents weather resistance; it does not give this review a basis to promise that every cushion stays dry in every exposure. Choose this model for a verified fit and suitable location, with the relevant care instructions still applying.
Keter Kentwood 92 Gallon: For a narrower covered edge
The Kentwood part 249623 uses resin, has a lockable lid with a separately purchased padlock, and is listed by Keter without piston assistance. Its shallower exterior makes it the narrow-footprint option of these three, provided the interior matches your own cushion arrangement.
The matching Amazon listing specifically recommends garage or covered-patio storage. We would make this a covered-location candidate rather than turning a general weather-resistance description into an unrestricted outdoor-storage recommendation.
Use the manufacturer’s dimension set in the table for this comparison, since the marketplace listing rounds some values differently. If your proposed fit depends on a fraction of an inch, confirm the current product and its usable opening before purchasing.
This is a sensible option to investigate when you have smaller or shallower cushions and want to preserve more walking room along a covered edge. It is a poor reason to force a deep lounge cushion into a different storage shape merely because the exterior looks convenient.
Think about how you will lift the lid and place each piece using the actual product instructions. A storage routine that works for one person on an ordinary evening is a more useful selection criterion than the label’s promise of extra seating or a fast assembly time.
Suncast DBW9200 99 Gallon: For a middle-depth wicker look
The Suncast DBW9200 manufacturer page identifies a 99-gallon resin box in Java, with the interior and exterior dimensions shown above. Its wicker-style texture offers a different visual match from the wood-look Keter choices.
The corresponding Amazon title uses Java while its overview also shows Mocha, so confirm the current color labeling and the DBW9200 model before ordering. Do not let a similar photograph stand in for checking the product identifier.
Its documented interior depth falls between the Kentwood and Westwood, while its interior width is the shortest in this group. That combination may suit a more compact cushion set, but it should make you check a long bench cushion carefully instead of assuming that 99 gallons beats 92 in every direction.
Use the box’s full instructions to settle placement, lid operation, permitted contents, and care. We have not independently measured the opening or tested water entry, and the comparison does not establish a performance ranking for those properties.
Choose it as the candidate to investigate when the documented cavity works and you prefer its woven appearance in your seating area. Move on if the shape of your stack needs the longer or deeper interior of another option.
Use a cushion example to catch a misleading fit
Suppose one of your own cushions measures 24 × 24 × 5 inches and you want it stored flat without compression. Its 24-inch plan dimension exceeds the listed interior depth of the Kentwood and Suncast in that orientation.
The Westwood’s listed depth exceeds that dimension, but that single comparison does not prove the cushion passes through the opening, clears the lid mechanism, or leaves enough room for the rest of the set. Confirm those remaining points rather than turning a close numerical match into a guaranteed fit.
Identify what would change your choice
Start with a candidate rather than a fixed winner: Westwood for the larger interior, Kentwood for the narrow covered location, or Suncast for its particular middle-depth proportions. Write down the observation that would rule that candidate out.
For the Westwood, the deciding issue might be the exterior space you give up beside the seating route. For the Kentwood, it might be a deep cushion that you want stored flat, while the Suncast could be ruled out by the length of a bench cushion.
Keep appearance as a separate preference after the fit questions. You can prefer a wood-look or wicker-style surface without treating that preference as evidence about water entry, strength, or the future condition of your fabrics.
If you are replacing a box you already own, note the specific problem you want the replacement to solve. More capacity is useful only when its shape and access arrangement address that problem, rather than reproducing the same awkward packing routine in a larger container.
Choose the box that supports your daily routine
Mark each candidate’s exterior footprint and leave the space its instructions and your handling routine require. Rehearse the trip from the seating area to the proposed box with the door, chairs, and lid in their normal positions.
If no candidate gives you a comfortable documented fit, split daily and seasonal storage or investigate a different product. Fewer cushions in daily circulation can be easier to manage than buying a larger box that blocks the patio.
Before checkout, confirm the exact model, current color, dimensions, included parts, delivery conditions, and care directions with the seller and maker as needed. Then choose the candidate whose actual shape and permitted use solve your storage problem, without relying on gallons to answer questions they cannot describe.
