Choosing between a metal vs resin deck box often comes down to how you plan to use the storage. Both options offer outdoor protection for cushions, tools, and patio gear. The main difference lies in the construction material and overall capacity. One uses a double-wall resin design with metal legs, while the other relies on thick, all-weather resin with a wood-plank look. You should compare their dimensions, locking mechanisms, and seating support to find the best fit for your space.

Choose Keter Westwood 150 Gallon Resin Deck Box if

- You prefer a rugged resin exterior with a wood-plank aesthetic.

Metal vs Resin Deck Box Comparison
Storage capacity
The Keter Westwood 150 Gallon Resin Deck Box offers significantly more interior volume than the YITAHOME 90 Gallon White Deck Box. With a 150-gallon capacity, the Keter unit can accommodate larger items such as bulkier patio furniture sets, extensive garden tool collections, or seasonal decorations that might not fit in smaller containers. The YITAHOME model provides 90 gallons, which is still ample for standard cushions and smaller tools. If you need maximum storage space for a large collection of outdoor gear, the Keter model is the clear choice due to its superior volume.
Footprint and size
You should consider the floor space available on your deck or patio when choosing between these two boxes. The Keter Westwood measures 61 inches in length and 28.3 inches in width, creating a long, narrow profile that requires a significant linear stretch of space. The YITAHOME deck box is more compact, measuring 44.5 inches in length and 22.8 inches in width. This smaller footprint makes the YITAHOME unit easier to place in tighter areas or against shorter walls. If you have limited square footage, the YITAHOME model is more practical.
Lid mechanism
Both deck boxes feature mechanisms to assist with opening the heavy lids, but they operate differently. The YITAHOME box uses gas struts to support the lid, allowing it to open smoothly and stay in place. The Keter Westwood utilizes an easy-lift mechanism designed for effortless opening and a quiet close. Gas struts often provide consistent resistance and hold the lid firmly at various angles. The easy-lift mechanism on the Keter focuses on smooth motion and reduced noise. Depending on your preference for how the lid behaves when open, one may feel more reliable than the other.
Seating durability
Both products are designed to double as extra seating, but they specify different load capacities. The Keter Westwood explicitly states it can seat two adults, suggesting a robust top structure capable of handling higher weight. The YITAHOME box mentions it doubles as extra seating or a table but does not specify a weight limit or number of people. If you frequently use the deck box as a bench for multiple people, the Keter model provides clearer assurance of its structural integrity for that purpose. The YITAHOME is suitable for occasional sitting or as a side table.
Construction material
The YITAHOME deck box is constructed from double-wall resin, which provides an advanced insulation layer. This double-wall structure acts as a resilient shield against extreme weather and helps keep the interior contents dry. The Keter Westwood is made from thick, durable resin with a wood-plank look, emphasizing ruggedness and resistance to rusting, peeling, and denting. While both are resin, the YITAHOME highlights its double-wall construction for added protection and insulation. The Keter focuses on the strength and aesthetic of its thick exterior. The double-wall design of the YITAHOME offers a specific advantage in thermal and impact protection.
Elevation design
How the box sits off the ground affects moisture protection and floor safety. The YITAHOME deck box rests on six heavy-duty metal legs, elevating the floor above wet grass and ground debris. This design prevents moisture damage to your belongings and keeps your patio floor scratch-free. The Keter Westwood does not list metal legs or an elevated base design in its specifications, implying it sits closer to the ground. If you are storing items on grass or uneven surfaces, the elevated design of the YITAHOME box provides better protection against ground moisture and debris.
Which deck box fits your needs?
You need maximum storage volume
The Keter Westwood offers 150 gallons of interior space. This capacity exceeds the YITAHOME model significantly. It accommodates bulkier patio furniture and larger tool collections. The extended length provides a wider footprint for organizing diverse outdoor items efficiently.
You want elevated moisture protection
The YITAHOME design rests on six heavy-duty metal legs. This elevated floor keeps contents above wet grass and ground debris. The double-wall resin construction adds structural resilience. The lift-off lid with gas struts ensures smooth access to your stored gear.
You prefer a compact footprint
The YITAHOME unit measures 44.5 inches in length. This is shorter than the Keter model's 61-inch length. The narrower width fits well in tighter patio spaces. It provides 90 gallons of storage without occupying excessive deck area.
You need easy lid operation
The Keter Westwood features an easy-lift mechanism for effortless opening. It closes quietly without requiring manual support. The Keter design prioritizes smooth lid movement. This mechanism reduces strain when accessing deep storage compartments regularly.
