Quick verdict
A 110-gallon resin deck box with a wood-grain finish, a lockable latch and slow-close hydraulic lid rods, with a reinforced lid the maker says works as a bench. It suits a household that needs cushion storage for a four- to six-seat patio set and wants the lid to drop gently around children and pets. The caveat is that no dimensions or lid weight rating are stated, and resin boxes are water resistant rather than sealed, so cushions still want a dry day before they go in.
Strengths
- 110-gallon capacity for a full set of cushions
- Slow-close hydraulic rods so the lid does not slam
- Lockable latch (padlock not stated as included)
- Reinforced lid with internal supports doubles as a bench
- Tool-free assembly the maker puts at about 40 minutes
- Fade-resistant PP with a wood-grain finish
Weaknesses
- No dimensions or lid weight rating in the listing
- Water resistant, not watertight; rain can reach the seams
- Side handles position it empty; 110 gallons is not a one-person carry when loaded
- Hydraulic lid rods are a known wear point on resin boxes

Who this deck box is for
A patio set with four to six chairs produces a stack of cushions that will not fit a 50-gallon box, and leaving them out is how they fade and mildew. The Greesum 110 gallon outdoor storage box is built for that stack: a dark wood-grain resin chest with a lockable latch, slow-close lid rods and a reinforced lid that the maker says can be sat on. It is also pitched at pool noodles, outdoor toys and the garden hand tools that otherwise live in a pile by the back door.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
The box arrives flat as a set of polypropylene panels with the lid, hydraulic rods, latch hardware and instructions, and Greesum says assembly is tool-free and takes about 40 minutes for one person. The listing states a 110-gallon capacity, integrated side handles, a lockable latch and a lid with internal supports so it serves as a bench or a side table. What it does not state matters as much: no exterior dimensions, no lid weight rating, no padlock in the box and no warranty term. Treat the bench claim as suitable for an adult sitting still rather than for children jumping.
Capacity and footprint
At 110 gallons this sits in the upper-middle of the deck box range, between the common 70 to 80 gallon boxes and the 120 to 150 gallon chests. In real use that is roughly the seat and back cushions for a six-seat dining set, or the cushions for a four-piece conversation set with room left for a couple of throw pillows and a hose nozzle. Because the maker publishes no dimensions, measure the cushions you own and compare them with a box you already know, and allow some empty space at the top so the lid closes without compressing anything against the hinge line.
Materials and weather resistance
The panels are fade-resistant polypropylene with a molded wood-grain texture, which is the standard material for this class. Resin does not rust, rot or need paint, and it shrugs off sun and freeze cycles far better than cheap plywood. It is water resistant rather than waterproof: owners of resin boxes in general report that wind-driven rain can find the lid seam and the corner joints, and that a box left in standing water will wick at the base. Put it under a cover or an eave if you can, raise it a fraction on pavers if the deck pools, and bring cushions out to dry fully before storing them for winter.
Lid, latch and lock
The slow-close hydraulic rods are the feature that separates this box from the cheapest chests. They hold the lid open while you load and let it settle rather than slam, which matters with small children and dogs around a patio. The latch accepts a lock; no padlock is stated as included, so budget for a small weatherproof one if the box will hold anything of value. Gas or hydraulic struts on resin lids are a known wear point across brands, so expect them to soften after a few seasons in full sun and check whether Greesum sells replacements before you rely on them.
Assembly and living with it
Tool-free resin boxes click together along panel channels, and the usual advice is to assemble it where it will live, because a built 110-gallon box is awkward to carry through a gate. The side handles are for nudging it into position when empty, not for lifting it full. Hose it out once a season, keep the lid clear of heavy planters in high summer so the resin does not take a set, and wipe the wood-grain texture rather than scrubbing it, since pollen settles in the grain.
Alternatives to Consider
The Keter Brightwood 120 gallon deck box is the closest brand-name equivalent, with a published weight rating on its bench lid and a wide dealer network for spare struts. The Suncast 99 gallon deck box is a little smaller and comes from a maker with a long record on resin storage. If cushions are the only job, the Lifetime 130 gallon box offers more room with steel-reinforced lid supports for a seated adult.
Verdict
Buy the Greesum 110 gallon outdoor storage box if you want a dark, wood-grain chest for a full set of cushions, value a soft-closing lid around children, and accept that an Amazon-native brand gives you thinner documentation than Keter or Suncast. Skip it if you need a published weight rating for seating, a watertight box for electronics, or a chest you can move around a deck once it is loaded.

Greesum calls it waterproof, but resin deck boxes in general are water resistant: the lid and walls keep rain off, while wind-driven rain can reach the lid seam and the corners. Store cushions dry and keep the box out of standing water.
The maker says the reinforced lid with internal supports works as a bench or side table. No weight rating is published, so treat it as seating for an adult sitting still rather than for jumping children.
The latch is lockable, but a padlock is not stated as included. Add a small weatherproof padlock if the box will hold anything worth taking.
Greesum says tool-free assembly takes about 40 minutes for one person. Build it where it will live, because a finished 110-gallon box is awkward to carry through a gate.
