First, consider what you are going to store in them. if you only need storage for small items like cushions, small toys, grilling implements and supplies, and table ware you can opt for small outdoor cabinet or a storage bench that works as both seating and storage. For large items such as pool gear, gardening supplies, and bigger toys, you may want to consider getting a bigger freestanding cabinet. For storage of really large items such as ride on toys, large garden tools, as well as outdoor furniture for the offseason, go for a really large storage cabinet. Some of the largest outdoor cabinets out in the market today can store as much items as a small shed, particularly if they offer vertical storage space.
The usual outdoor furnishing that contains a storage space is an outdoor bench. Instead of the usual plank of wood with two legs on both ends, outdoor benches these days have boxed structures which can be equipped with drawers or a top-removing lid. You can store whatever knick knacks you need to spruce up your backyard for your own or party use.
