HS score
Methodology: The House Staples Score is our 0–5.0 analytical rating of a product’s capacity, materials, and construction standards, independent of crowd-sourced user reviews. | 4.6 | 4.5 | 4.5 | 4.4 | 4.4 | 4.3 | 4.2 | 4.2 | 4.1 | 4.1 | 4.0 |
| Notes | The resin is ventilated rather than sealed, so it sheds moisture well but is not the place for anything that must stay bone dry, like paper or seed. · Leave a foot of clear space behind the box so the lid can swing back fully and you can get both hands on the support rod. | If the box will live in full sun all day, keep cushions inside it rather than sunscreen or anything that can melt. · Shimmed level matters here, because a box on uneven pavers will let the lid sit slightly askew and break the seal. | Because it rolls, park it against a wall or set a wheel chock if your deck has any slope. · Gas struts open with force, so stand to the side of the lid rather than directly over it when you first release the catch. | If you use it for parcels, put it where the carrier can actually reach it and leave the padlock off until you are ready to secure it. · Empty it is light enough to move in a storm, so load it or tuck it against a wall if your deck catches wind. | Set it on a level surface, since a box on sloped decking puts the lid and gas rods out of alignment. · Move it with the side handles only when it is empty, because 100 gallons of damp cushions makes it unwieldy for two people. | Give it about two feet of clear space in front, because a lid on a box this deep needs room for you to lean in and reach the bottom. · Set it on level decking before you load it, since a 57-inch resin shell will rock and strain its seams on uneven pavers. | Leave clearance above it for the lid to swing fully open, which is easy to forget if you tuck it under a railing or a window sill. · Because the top is a seat, put it where someone would actually want to sit, such as beside a lounger, instead of in a corner where it just becomes a box. | Set it on a flat, level surface, because a resin box of this size will twist slightly on uneven pavers and the lid can stop seating cleanly. · Leave roughly a foot of clear space above the closed lid so the struts can swing it fully open against a wall or railing. | Give the back of the box several inches of clearance from a wall or railing so the lid can swing fully open. · Sitting on the lid is fine, but standing on it is not what the seating rating covers, so keep kids from using it as a launch pad. | Assembly is six side panels fitted together, so clear a flat patch of floor and keep the instruction sheet with you for the five minutes it takes. · Resin is waterproof and UV resistant, but anything stored damp stays damp once the lid closes, so let cushions dry before they go in. | Leave a foot or so of clearance above the lid, since the hydraulic rods swing it up and back when it opens. · The side handles let you slide it, but empty it first, because a full box of wet cushions is far heavier than the resin shell alone. |

ATMELT Outdoor Storage Box, 170 Gal Waterproof Resin Deck Box w/Support Rod
$94.99
This is a polypropylene resin box with a woven rattan texture molded into the panels, sized at 170 gallons so it swallows cushions for a full seating set rather than just a few pool floats. The panels snap together without tools, which means one person can put it together in an afternoon, and the resin will not rust or peel the way a metal or painted wood box does. A support rod props the lid while you load it, so you need to reach in and set that rod yourself instead of having the lid stay up on its own. Skip it if you want something small enough to live beside a chair, because at this capacity it reads as a bench and takes a bench's worth of wall.

Dimensions and capacity from the product page when available. Room notes use our clearance standards for this category.
Why it makes the list
- The 170-gallon capacity is bigger than most of the 100 to 150 gallon boxes here, so a full set of seat and back cushions fits without stacking them awkwardly.
- Polypropylene resin does not rust, dent, or peel, which matters on a deck that gets sprinklers or salt air year after year.
- The snap-on panel assembly needs no complex tools, so you are not sorting bolts on the ground for an hour.
What to keep in mind
- The lid is held by a manual support rod, so it will not stay open by itself the way a strut-assisted box does.
- The molded rattan texture has grooves that catch pollen and dust, so you will be wiping it down more often than a smooth-sided box.

Keter Westwood Outdoor Storage Deck Box, 150 Gallon, Dark Grey
$145.29
Mechanically this is the same 150-gallon Westwood box, with the same easy-lift lid, the same two-adult seating rating, and the same padlock-ready hasp, but it comes in dark gray instead of the warmer wood tone. The darker color hides pollen, rain spots, and the gray film that collects on a patio far better, though it also runs hotter in direct afternoon sun. Choose this one over the lighter Westwood purely on how it sits next to your existing furniture. Skip it if your deck is already dark and you want the box to lift the color scheme rather than disappear into it.

Why it makes the list
- Dark gray resin disguises pollen and water spotting between cleanings better than a pale finish does.
- The 150-gallon capacity handles bulky items like floats and folded loungers, not only cushions.
- The quiet-close lift mechanism means the lid does not drop on your fingers when a gust catches it.
What to keep in mind
- The dark surface absorbs heat, so the lid gets genuinely warm to sit on during a sunny afternoon.
- Dark gray shows chalky residue from hard-water sprinklers more visibly than the wood-tone version.

EFU Outdoor Storage Box, 150 Gal Gen 2 Resin Deck Box w/Gas Struts &…
$85.49
The EFU runs 150 gallons like the Keter Westwoods, but it solves two everyday annoyances they do not, because gas struts hold the lid wide open while you load it and wheels let you move it off the deck boards to sweep underneath. The lid carries a stated 300-pound capacity, so it takes seating, and there is a padlock hole if you keep anything worth locking up. The resin is scratch-resistant and wipes clean, which is the part you notice after a season of muddy sports gear. Skip it if you want the molded wood-plank texture the Keter boxes have, since this one has a plainer face.

- Decks where the box has to move
Dimensions and capacity from the product page when available. Room notes use our clearance standards for this category.
Why it makes the list
- Gas struts hold the lid open on their own, so you can load cushions with both hands instead of propping it with your shoulder.
- The wheels let one person roll it aside to sweep or hose the deck, which is awkward with a fixed box.
- The stated 300-pound capacity means the lid takes a couple of people sitting without flexing.
What to keep in mind
- Gas struts are a wear part, so after several years of cold winters the lid may start drifting down on its own.
- The surface is plain resin without the plank texture of the Keter boxes, so it looks more like utility storage.

MAIUSCOLI 35 Gallon Outdoor Deck Box Lockable Waterproof Storage Black
$26.99
The MAIUSCOLI holds 35 gallons in a black resin shell with a tight-sealing lid, reinforced panels and impact-resistant corners. The panels interlock, so it goes together in minutes without a screwdriver, and the molded handles mean one person can shift it across a deck once it is empty. The product page also suggests it as a parcel drop box by an entry door, which is a fair use given the lockable design. Skip it if you want a lid you can sit on, because nothing in its specs supports weight on top.

Why it makes the list
- Tool-free interlocking assembly means you can have it built and loaded within minutes of opening the carton.
- Sturdy handles on the body make it practical to move the box seasonally instead of leaving it in one spot forever.
- The tight-sealing lid plus UV-resistant resin keeps cushions dry and stops the black color from washing out in summer sun.
What to keep in mind
- There is no stated seating capacity, so treat the lid as a lid and not as a bench.
- No lock is supplied, which matters more here because the product page pitches it as a place to hold delivered packages.

Devoko 100 Gallon Waterproof Deck Box, Resin Large Outdoor Storage Box
$79.99
Devoko gives you 100 gallons in an interior that measures 47.8 by 21.4 by 24.6 inches, which is tall enough that cushions can stand on edge instead of being crushed flat. Two gas rods lift the lid and let it settle slowly, so it will not slam on fingers, and the stated seat capacity of 500 pounds covers two adults. Side handles let two people shuffle it across a deck once it is empty. Skip it if you want a huge single container, because the ATMELT at 170 gallons and the 300-gallon boxes on this list hold far more.

Dimensions and capacity from the product page when available. Room notes use our clearance standards for this category.
Why it makes the list
- The 24.6-inch interior height lets thick seat cushions stand upright, so you fit more in than the depth alone suggests.
- Two gas rods ease the lid closed instead of letting it drop, which matters when kids are the ones digging for pool toys.
- The published 500-pound capacity is the highest seat rating among the mid-size boxes here, so it holds two adults comfortably.
What to keep in mind
- At 100 gallons it fills fast if you are storing bulky floats as well as cushions.
- Gas rods are a wear part, so after several seasons outdoors the lid may need a firmer hand to stay up.

Decksplore 300 Gallon Outdoor Storage Box Resin Deck Box All Weather…
$259.64
This is a resin box measuring 57.87 inches long, 32.24 inches deep and 33.66 inches tall, which is nearly five feet of wall and chest height on a person of average build. The 300-gallon capacity means a full set of patio cushions, pool floats and a leaf blower can live in one place instead of being split between two smaller boxes. The lid is reinforced for a padlock, though no lock comes with it, and the whole thing snaps together in 10 to 30 minutes without tools. Skip it if your deck is narrow or your railing is short, because at almost 34 inches tall it will read as a wall rather than a bench.

Dimensions and capacity from the product page when available. Room notes use our clearance standards for this category.
Why it makes the list
- The 57.87-inch length takes long items like folded umbrellas and pool poles that a 30-gallon side table box cannot begin to hold.
- The resin carries built-in UV inhibitors, so the black finish is meant to hold its color through full sun rather than chalking to gray.
- Assembly is snap-together and takes 10 to 30 minutes, so you are not sorting screws on a hot deck.
What to keep in mind
- At 33.66 inches tall it sits well above normal bench height, so sitting on it is awkward even though the product page suggests it.
- No padlock is included, so you have to buy and fit one yourself before the lockable lid means anything.

Greesum Outdoor Storage Box 31 Gallon Storage Box with Lid for Patio…
$26.59
This is a 31-gallon resin box in dark brown, which is about the size that holds a couple of seat cushions, a hose nozzle and a bag of pool chemicals rather than a full set of furniture covers. The hydraulic bracket holds the lid open instead of letting it fall on your hands, and the top is rated to hold one adult, so it works as a perch or a side table next to a lounger. Everything needed for assembly ships in the carton, including the tools. Skip it if you are storing long-handled rakes or folded loungers, because at this capacity nothing tall is going in upright.

Dimensions and capacity from the product page when available. Room notes use our clearance standards for this category.
Why it makes the list
- The hydraulic bracket keeps the lid propped while you load, which matters on a box this small where you end up reaching all the way to the bottom.
- Resin construction resists water, corrosion and UV fading, so it can stay out in full sun without the graying that hits wood and rattan.
- The shell is built to carry one adult, so the 31 gallons of storage doubles as an extra seat when guests turn up.
What to keep in mind
- Thirty-one gallons is genuinely small, so anyone storing furniture covers or a pool vacuum should look at the 92-gallon Kentwood or larger instead.
- The lockable holes only work once you supply your own padlock, since none comes with it.

KAMABOKO Outdoor Storage Box, 150 Gallon Deck Box Outdoor Waterproof
$94.99
The KAMABOKO is a 150-gallon PP resin chest with a wood-grain skin, and it holds a full cushion set plus a coiled hose without you having to fold anything down. Two hydraulic struts carry the lid open for hands-free loading and regulate the close, and the published top rating of 680 pounds means two adults on it is a normal use rather than a gamble. The lid is shaped to shed rainwater off the sides instead of pooling at the seams. Skip it if you want a box that arrives whole, because this one ships flat and you assemble it.

Dimensions and capacity from the product page when available. Room notes use our clearance standards for this category.
Why it makes the list
- Dual gas struts hold the lid up on their own, so you can use both hands to lift a stack of cushions in.
- The 680-pound published support figure covers two adults sitting on the top, which makes it usable as a bench at a crowded cookout.
- Molded side handles let two people scoot it along a deck when you need to sweep underneath or move it for winter.
What to keep in mind
- The lid is lockable but no lock is included, so you buy a padlock separately if security matters.
- The wood-grain molding is pressed into the resin rather than being real plank, so it reads as a texture up close rather than as lumber.

Keter Westwood 150 Gal Outdoor Storage Box for Patio and Pool Accessories
$144.99
This is a 150-gallon resin box with a molded wood-plank texture, and the lid is built to hold two adults, so it earns its footprint twice over on a crowded patio. The easy-lift mechanism takes the weight of the lid on the way up and sets it down quietly instead of slamming, which matters when you are closing it one-handed with cushions in the other arm. It takes a padlock if you want it locked. Skip it if you need something small enough to tuck beside a door, because a box this size wants a real stretch of deck.

Dimensions and capacity from the product page when available. Room notes use our clearance standards for this category.
Why it makes the list
- The 150-gallon interior swallows a full set of chair cushions and pool floats rather than making you choose between them.
- The lid is rated for two adults to sit on, so it works as overflow seating when people come over.
- The resin body will not rust, peel, or dent the way a painted wood or metal box does after a few seasons outside.
What to keep in mind
- The wood-plank look is molded resin, so up close it reads as plastic rather than lumber.
- It has no interior shelf or divider, so small hand tools sink to the bottom unless you store them in a bin.

Devoko 30 Gallon Resin Deck Box Waterproof Outdoor Storage Box for Patio…
$27.54
This is a 30-gallon resin box measuring 22 by 16 by 20 inches, which is about the footprint of a kitchen trash can and small enough for a balcony corner or the end of a narrow porch. The 20-inch height puts the lid at seat level, and the published load limit is 220 pounds, so an adult can sit on it while someone else takes the chair. Six panels snap together, and the empty box weighs only 8.8 pounds, so you can drag it inside for winter. Skip it if you need to swallow full patio chair cushions, because 30 gallons holds pool toys, hand tools and a folded towel stack and little more.

Why it makes the list

- The lid has a raised section only 1 inch high with smoothed edges around it, which makes sitting on the top reasonably comfortable.
- It accepts a padlock, so chlorine tablets and garden tools stay closed off from kids and animals.
What to keep in mind
- Thirty gallons is genuinely small, so bulky seat cushions and long-handled tools will not fit inside.
- The light 8.8-pound shell can skid or tip on a windy balcony when the box is close to empty.

GYMHILL 190 Gallon Outdoor Storage Box Waterproof Lockable Deck Box, Black
$99.99
This is a wood-grain resin box that holds 190 gallons, which puts it between the common 150-gallon boxes on this list and the oversized 300-gallon Decksplore. The lid rides on hydraulic rods that slow the open and close, so it does not slam on fingers, and the published load limit of 550 pounds means you can sit on it or set a tray down while you work. It assembles from snap-together panels without tools and has molded side handles for repositioning. Skip it if you want a small box that doubles as a side table, because the 30-gallon Keter City suits that better.

Why it makes the list

- Hydraulic buffer rods hold the lid through a slow open and close, which keeps it from dropping on hands when you are loading cushions.
- Panels snap together with no tools, so one person can build it on the patio where it will live.
What to keep in mind
- At 190 gallons it needs a long stretch of wall or railing, so it will crowd a small balcony where a 30-gallon box fits easily.
- The wood-grain finish is molded resin, so it reads as textured plastic up close rather than as real lumber.

Before you buy
Run this list after you pick a box and before checkout.
- Gallons. A full set of chair cushions usually wants about 100 gallons.
- Lid. Confirm whether the top is rated as a seat or is only a cover.
- Footprint. Measure the deck, and leave room for the lid to open.
- Material. Resin handles rain. A wood look still has a care line.
- Lock. A latch keeps the lid down in wind.
- Return terms. Keep the carton until the box is on the deck and the lid closes over the cushions.
How we made this list
We compared 11 options for deck boxes on gallon capacity, material, and the lid. Furniture covers, planters, and coolers were cut.
- A box. The product had to be an outdoor storage chest with a lid.
- Capacity. Gallons had to be published.
- Lid. We noted when the top is rated as a seat.
- Cut duplicates. Near twins kept the clearer sheet and stronger score.
FAQ
How many gallons does a deck box need for chair cushions?
A set of four chair cushions usually wants about 100 gallons or more. A smaller box holds a couple of cushions and a cover, and the gallon number on the product page is the one to check.
Can you sit on a deck box?
Some lids are rated as a seat and some are only a cover. The product page has to say the lid holds a person before you use it as a bench.
Where should I buy these?
Use the Buy buttons on this page for the exact products we compared. Confirm gallon capacity, whether the lid is a seat, and the return policy on the product page before checkout. Prices move frequently.
This is general home-furnishing guidance, not structural or safety advice. Confirm weight limits, tip-over anchors, and local building rules where they apply.
