A storage bench is one of those pieces of furniture that does double-duty. You can use it to store all sorts of things – from blankets to seasonal clothing, skates, boots and more – and it also serves as a place to sit. These are easily available in resin or plastic models, but if the beauty of your patio furniture is important to you, then you may want to invest in a model made of wood, like cedar or teak.
I like the size of this one – I could store a ton of stuff in there:
