Flamaker Outdoor Storage Box 100 Gallon Waterproof Deck Box - Lockable

In this review the Flamaker Outdoor Storage Box 100 Gallon proves to be a sensible choice for homeowners who need a weatherproof, multipurpose storage solution for patio cushions, pool supplies, or garden tools. The single biggest reason to buy is its combination of a true waterproof resin construction with practical details like a lockable lid and air rods that prevent sudden closing. It is a straightforward, no-frills deck box that delivers capacity and durability without a high price tag, and it performs well as both storage and occasional seating.

Key Features

• 100 gallon capacity: Provides roomy storage for several patio cushions, pool accessories, or a mix of garden tools and toys so outdoor clutter stays protected.
• All-weather resin material: Waterproof and UV resistant construction keeps contents dry and the exterior from fading for long outdoor use.
• Metal reinforcement bar: A reinforced top prevents the lid from bending under sun and rain, helping the box keep its shape over time.
• Lockable lid: A locking hole in the lid lets you secure contents against loss, useful at shared poolside or porch areas.
• Air rod hinges: Slow-open air rods prevent the lid from slamming and reduce the risk of hand clipping when accessing stored items.
• Dual handles and lightweight build: Two handles on each side and a manageable weight make it easier to move the box when needed.

Who It's For

The Flamaker deck box is best for homeowners or renters with patios, balconies, decks, or poolside spaces who need a waterproof, attractive storage bench that doubles as occasional seating. It suits people who want simple assembly and functional features like a lockable lid and slow-close air rods without spending on premium hardwood or metal alternatives.

This box is less suitable for those who require permanent heavy-duty seating for multiple users at once (the seat rating is 150 lb) or for buyers who need a perfectly color-matched finish for high-end decor, since actual color may vary slightly by monitor and lighting.

Pros & Cons

Pros

• Generous storage capacity that handles several cushions or a mix of outdoor items with room to spare.
• Durable, waterproof resin with UV resistance keeps contents dry and reduces fading outside.

Cons

• Assembly experiences vary; some users find set up straightforward while others report it can be challenging and time consuming.
