NBYSGO 31 Gallon Resin Deck Box Review
As an Amazon Associate we earn from qualifying purchases.
This NBYSGO Outdoor Storage Box Resin Deck Box 31 Gallon review looks at a compact, rattan-look black resin box with a lockable lid, sold for patio cushions, pool supplies and package delivery. The listing makes several strong claims, including a 500 lb bench rating and UV resistance, and this review checks what the listing states against two non-retail sources. The box itself was not examined, so every product fact below comes from the Amazon listing or is attributed to a named source.
How we chose and checked this review
The Amazon listing was read in a read-only session on 2026-10-27. The title, brand, specification fields and About this item bullets were recorded from that text. Customer review text on the page was not used as evidence for any product claim. Two non-retail sources were opened and their quoted passages were compared with the fetched text. Nothing in this review is based on handling the box.
Quick answer
- The listing describes a 31 gallon black resin deck box with a rattan-look finish and a lockable lid. The lock is not included.
- The listing says the box supports up to 500 lbs as a bench. No source reviewed here confirms that rating, and the CPSC guidance on lid supports suggests checking the lid before using the box as a seat.
- The listing claims weatherproof and UV-resistant resin. A 2020 study of polypropylene films supports the general idea that UV stabilizers can be studied, but it does not test this molded box.
- Check that the lid stays open in every position before use, since the CPSC guidance on storage chests names unsafe lid supports as the hazard.
What the listing says
The listing names the brand as NBYSGO, the color as Rattan Black, the material as Resin, the special feature as Lockable and the style as 31 Gallon. The 31 gallon option is the selected one on this page. The bullets describe the box as lightweight, with a compact square shape and a wood or wicker look. They describe the resin as resistant to water, UV rays, rust and fading. They say the box doubles as a bench that supports up to 500 lbs and works as a place to receive packages. The lid is lockable, but the bullets state that the lock is not included. Assembly is described as tool-free, using panel clips, and the side handles are described as letting one person move the box.
The listing does not give exterior or interior dimensions in the captured text, and the measurements table did not come through. The 31 gallon capacity is the only volume figure captured.
Size and footprint
A 31 gallon box is the smallest of the sizes offered here. That capacity suits a set of small cushions, a few pool toys or a small collection of garden tools. Buyers planning to store larger cushions should compare the internal length, width and height against their cushions, because the listing does not state internal dimensions in the captured text. Measuring before ordering is the simplest way to avoid buying a box that will not close.
The square shape described in the listing is a practical detail for a patio corner. The listing does not say whether the box is meant to sit on a flat surface such as a deck board or concrete. A level base is standard advice for any resin box of this kind, but the listing itself is silent on it.
Lid, lock and seating
The lid is the part of a deck box that most often causes injury when it fails. The Consumer Product Safety Commission published guidance in March 2014 on storage and toy chests. The agency wrote: “If the lid support does not keep the lid open in every position, you should remove the lid’s support or replace it with a spring-loaded lid support that will keep the lid open in any position.” That guidance is written for chests, and the agency does not say it applies to this product. It is still the closest federal guidance available, and its message applies here: a lid that falls shut on hands, head or neck is a hazard.
The lock is described as part of a lockable lid, and the bullets say the lock is not included. The listing does not say what type of hasp the box has, so a buyer will need to confirm that a padlock fits before buying one.
The 500 lb bench rating is the claim most in need of care. The listing presents the box as a bench, but it does not say how the rating was measured, on which part of the lid, or whether the rating applies to a seated adult. A lid designed to be stood on is a different question from a lid designed to be sat on, and the listing does not separate the two. Until a written rating is confirmed, treating the box as a storage container rather than a seat is the cautious reading of the page.
Material and UV resistance
The listing says the box is made of resin and resists UV and fading. It does not name the polymer. Polypropylene is a common base for molded outdoor boxes, and a 2020 study in the journal Materials looked at how UV stabilizers protect the material. The authors wrote that “Hindered amine light stabilizers (HALSs) and nano ZnO were used to stabilize polypropylene (PP) film-based formulations that were exposed to ultraviolet (UV) light for different lengths of time, simulating the harsh outdoor weather of Dallas, Texas, USA.” That study used thin film samples under accelerated exposure, so it shows that stabilizers can be measured in polypropylene but does not show how a molded NBYSGO box will look after several years in the sun.
Keeping a resin box out of direct sun is the simplest way to slow fading. A shaded spot on a patio or porch will usually keep the color more even than a fully exposed corner, and the listing does not say whether the color is fade-tested to a standard.
Assembly and handling
The listing says assembly is tool-free with panel clips and can be done by one person in minutes. Snap-together panels are common in this category and are usually quicker to build than screwed boxes. The listing does not state the weight of the 31 gallon box, which matters for moving it when full. Lifting with the side handles and keeping the load low is the safer approach.
Who this box suits
The box suits a buyer who wants a compact, lockable place for cushions, pool toys or small tools on a patio or balcony, and who does not plan to sit on it. It is a weaker choice for anyone who needs a verified load rating, a large interior or a box to stand on. The listing’s bench claim should be treated as unconfirmed until a written rating is available.

Frequently asked questions
Can this NBYSGO box be used as a bench? The listing claims a 500 lb bench rating, but no source reviewed confirms it. Ask the seller for a written load rating before sitting on the lid.
Does the box come with a lock? No. The listing says the lock is not included, so a padlock must be bought separately and checked for fit.
Is the 31 gallon size enough for cushions? That depends on the cushion size. The listing does not state internal dimensions, so measure before buying.
What we could not verify
- The 500 lb bench rating and how it was measured.
- The weatherproof and UV-resistance claims for this molded box.
- The polymer used. The listing says resin and the title does not name a polymer.
- The interior dimensions, weight and lid hinge design of the 31 gallon size.
- Whether the lock hasp accepts a standard padlock.
- Any warranty term.
What the sources do not say
The CPSC guidance covers storage and toy chests and does not name this product or any deck box. The polypropylene study uses thin film samples under laboratory UV conditions, not molded yard boxes. Neither source gives a load rating, a service life or a warranty for this box.
