Quick verdict: Choose resin when a suitable low-maintenance storage box meets your cushion dimensions and exposure needs. Choose wood when its appearance and repairable finish are worth the upkeep. Verify the exact box’s water protection; neither material name guarantees dry, mould-free contents.

Measure the cushions before measuring the patio
A box can fit neatly against a wall and still fail the purpose you bought it for. Measure the widest cushion and the stacked height of the set. Check usable interior dimensions, not just the exterior or the advertised volume in litres or gallons.
Keter’s range illustrates weather-resistant resin construction. IKEA’s NÄMMARÖ storage box illustrates an outdoor wood design with its own care guidance. Those examples do not establish identical water protection, seating ratings or useful dimensions across all boxes made from the same material.
When resin is good value
Resin suits someone who wants to avoid a regular wood-finishing routine. Choose a box with a lid and opening arrangement that make the stored items easy to reach. A suitable hinge aid can be convenient, but inspect the instructions for safe assembly and use.
Check the floor and panel construction as well as the lid. A low price is less attractive if the assembled unit will not support the intended contents. Put it on an appropriate level base and follow any load limits rather than assuming thick-looking panels establish strength.
When wood earns its upkeep
Wood can fit a patio style you prefer and may offer a finish you can maintain or refresh. It is worth buying when that appearance matters enough to justify the care routine specified by the maker.
Inspect gaps, ventilation, finish and the way rain can reach the lid and joints. Some wood boxes are useful outdoor storage without being sealed cushion chests. Do not treat an outdoor-use label as a promise that fabric can remain inside through any weather.
Moisture management matters in either box
Allow cushions to dry before storing them. Closing damp fabric in an enclosure does not remove its moisture. Follow the cushion maker’s storage instructions as well as the box instructions, and inspect the contents periodically.
A box that resists rain from above may still sit where runoff or snow collects. Choose the location around the actual exposure, not a sunny catalogue photograph. Protect items that need a higher level of weather protection than the enclosure provides.
Check seating, locks and winter storage
If you want the lid to serve as a seat, buy a model explicitly rated for that use and follow its load limit. A flat top does not establish seating approval. A padlock provision may discourage casual access without making the box a high-security storage system.
For Canadian winters, confirm the box’s seasonal guidance and the contents’ needs. Bulky cushions may still need indoor storage. Compare delivery, assembly and replacement hardware alongside the purchase price; a bargain kit missing usable instructions or support can cost time to resolve.
Final buying recommendation
Buy resin for a suitable low-maintenance enclosure; buy wood for an appearance and upkeep routine you accept. Spend first on internal fit and verified weather protection. Skip the purchase if an existing dry storage space already keeps the cushions accessible.
