A storage bench is two purchases wearing one lid: the box that swallows your cushions and the seat you actually sit on. Buy for the box and you get a bench nobody wants to sit on; buy for the seat and your cushions spend the season getting rained on. The bench that wins does both jobs without asking you to think about either one, and that is a shorter list than the aisle suggests.
For most patios, the pick is the Keter Westwood 150-gallon. It holds a full cushion set with room left over, its lid is rated to 660 pounds, and two adults can sit on it without wondering whether they should. The Keter Kentwood 92-gallon is the runner-up for smaller patios, and the Devoko 100-gallon is the mid-size pick if the Westwood is more bench than your space allows. One popular bench does not make the cut, and the reason is simple arithmetic.
The four benches, side by side
| Bench | Capacity | Size | Seat weight | Best for |
|---|---|---|---|---|
| Keter Westwood 150 | 150 gallons | 61″ L x 28.3″ W x 25.2″ H | 660 lb | Full cushion sets |
| Keter Kentwood 92 | 92 gallons | 50.4″ L x 21.2″ D x 23.2″ H | 573 lb | Smaller patios |
| Devoko 100-gallon | 100 gallons | 48″ L x 22″ W | Occasional seating | Mid-size patios |
| Suncast 22-gallon seat | 22 gallons | 15″ L x 15″ W x 20″ H | Single seat | Throw pillows only |
Best overall: Keter Westwood 150-gallon
The Westwood wins on the number that matters most, which is how much it actually holds. At 150 gallons and 61 inches long, it takes a full set of patio cushions — seat and back cushions for four chairs, plus the throw pillows — in one load, instead of the two trips a smaller box demands. The lid is rated to 660 pounds, so it seats two adults with a margin that does not require anyone to do mental math before sitting down.
It is resin, which means it will not rot, rust, or need a coat of anything before winter. The lid locks, so the cushions stay put when the wind picks up, and the box weighs 39.1 pounds empty, which is light enough to slide across the patio when you rearrange and heavy enough to stay where you left it. Keter builds it as a two-person bench seat, not as a box that happens to have a flat lid, and the difference shows in how solid it feels under weight.
Pros: largest capacity here by a wide margin; 660-pound lid rating seats two adults comfortably; lockable lid; resin needs no seasonal upkeep.
Cons: at 61 inches long it needs a real stretch of flat patio; the 25.2-inch height sits higher than a standard chair, so it perches more than it lounges.

Runner-up: Keter Kentwood 92-gallon
The Kentwood is the Westwood’s smaller sibling, and it is the right call when 61 inches of bench is more than your patio can spare. At 50.4 inches long and 92 gallons, it still swallows the cushions for a four-chair set if you fold them in flat, and its lid is rated to 573 pounds — again, two adults, no second thoughts. It carries a 2-year warranty, which is the kind of detail that matters more than it sounds like it should, because it tells you the maker expects the hinges and lid to outlast a season.
What you give up against the Westwood is the margin. With 92 gallons instead of 150, there is no room for the extras — the throws, the pool toys, the garden tools that migrate onto the patio by July. If your cushion set is the whole job, the Kentwood does it in a smaller footprint. If the bench is also the place where everything else ends up, buy the bigger box.
Pros: fits patios the Westwood cannot; 573-pound seating rating; 2-year warranty; same low-maintenance resin.
Cons: 92 gallons leaves no room for extras once the cushions are in; at 50.4 inches it is still a long box for a small balcony.

The same idea in a smaller footprint — full cushion set, two-adult lid, tighter patio.
Best mid-size: Devoko 100-gallon
The Devoko sits between the two Keters on capacity — 100 gallons in a 48-inch box — and it is the pick for the patio that wants a full-size bench without the full-size footprint. The interior measures 47.8 inches long, so seat cushions slide in flat instead of folded, and the resin body is waterproof with a lockable lid. Amazon lists it at 500-plus bought in the past week, and that kind of volume usually means the assembly instructions have been debugged by sheer repetition.
The trade-off is the lid. Devoko does not publish a seating weight rating for this box, so while it is built as a bench, the lid is best treated as occasional seating — a perch while you tie a shoe, not the second chair at the table. If the bench will be sat on every evening, the Westwood or the Kentwood, with their published ratings, is the safer buy.
Pros: 100 gallons in a 48-inch box; cushions fit flat; waterproof resin, lockable lid; widely bought, so assembly is well-trodden ground.
Cons: no published seating weight rating, so treat the lid as occasional seating; the rattan-look pattern will not suit every patio.

Not recommended: Suncast 22-gallon storage seat
The Suncast 22-gallon storage seat is a good little box for the wrong job. At 22 gallons and 15 by 15 by 20 inches, it holds a couple of throw pillows and a garden trowel — it does not hold a patio cushion set, and no amount of careful folding changes that. It is a side table with a lid, and it is priced and shaped like one, which is fine if what you need is a side table. As a storage bench for cushions and tools, it asks you to buy a second, bigger box within a season.
Skip it unless your whole patio is a balcony and your whole cushion collection is two throw pillows. Everyone else should put the money toward a bench that fits the job on the first try. If you want the full reasoning on what size actually fits what, our storage bench sizing guide works through the gallon math.
What the winner is worse at
The Westwood’s only real weakness is its size, and it is worth saying plainly before you measure. Sixty-one inches is five feet of patio, and on a small deck that is the difference between a bench and a wall. It is also 25.2 inches tall, which sits higher than a dining chair, so it works better as a perch at the edge of the patio than as a seat pulled up to the table. If your patio is tight, the Kentwood’s 50.4 inches is the honest compromise — you lose 58 gallons of capacity, but you gain a bench that fits the space you actually have.
Bench, deck box, or shed?
A storage bench is a deck box with a seat-rated lid, and the choice between them comes down to whether you need the seat. If you only need storage, a plain deck box gives you the same gallons for less money — our deck box roundup covers the best of those. If you need seating too, the bench earns its keep every evening someone sits on it. And if your storage problem is bigger than cushions — mowers, bikes, a decade of tools — no bench solves it, and our bench vs. deck box vs. shed comparison lays out where each one stops making sense.
Material matters as much as size, and it is the one choice that decides how long the bench lasts. Our resin vs. wood comparison works through what rain and sun do to each one. If you are still deciding between gallons, our deck box sizing guide covers the same math for plain boxes.
Bottom line
Buy the Keter Westwood 150-gallon if it fits your patio, because 150 gallons and a 660-pound lid end the argument about what goes where. Buy the Keter Kentwood 92-gallon if your patio is tight — it holds the same cushion set in ten fewer inches. Buy the Devoko 100-gallon if you want the middle ground and will treat the lid as a perch rather than a chair. Do not buy a 22-gallon box for a cushion set, whatever the listing calls it. Measure the patio, count the cushions, and let those two numbers pick the bench.
