Product Overview

NUNU LAB builds this as a large-capacity, multi-purpose outdoor storage box rather than a simple lidded bin, sized to hold patio cushions, garden tools, pool accessories, sports equipment or firewood while also functioning as extra seating or a side table.

The resin construction is positioned as weatherproof across rain, snow and sun exposure, with a stable, non-wobbling base once assembled.

Key Features

340 gallon capacity

Holds cushions, tools, pool gear or firewood.

Hydraulic lid system

Opens effortlessly, closes softly.

660 lb bench rating

Doubles as seating or a side table.

Weather-resistant resin

Resists rust, peeling and dents.

Lockable design

Accepts a lock for added security (not included).

Design and Build Quality

The box is finished in Rattan Black resin, chosen for resistance to rust, peeling and dents compared to metal outdoor storage. The listed footprint is 75.08 inches long by 34.37 inches wide, weighing 86.42 pounds; the listing's separate height figure of 6.69 inches reads as a packaged or component dimension rather than the box's true assembled seat height, given the box is marketed as bench-height seating.

Access is through a hydraulic piston lid system, which the listing says opens effortlessly and closes softly rather than slamming or needing to be held. The model is listed simply as TT, which is not a descriptive manufacturer name.

Performance in Everyday Use

As a bench, the box carries a stated weight capacity of up to 660 pounds, enough for multiple people to sit on at once according to the listing. Waterproofing is built in to keep stored items dry, with the listing also mentioning the box can double as a secure package delivery box by a front door.

The box is described as lockable, which the listing clarifies means it accepts a lock for added security; a lock itself is not included in the purchase.

Final Verdict
Solid Pick
8.2/10

A 340 gallon resin deck box with a hydraulic lid, a 660 pound bench weight rating and weatherproof construction in Rattan Black. It suits large-capacity outdoor storage and extra seating well, with the one real catch being the lockable design needs a separately purchased lock.

Why buyBackyards, patios and poolside areas needing large waterproof storage that can also double as a bench or table.
Why skipA lock is not included, so the lockable design needs a separately purchased padlock to actually secure the contents.
