Old pallets or crates are a fine alternative to the traditional coffee table and are incredibly versatile too. The ones here have simply been turned upside down — but you could screw yours together if you tend to move your furniture around a lot. You could also stack them or cut them down to size or use one pallet and elevate it with small apple crates for example. A coat of paint will transform the trusty courier once again.
If you get a tufted ottoman consider the depth of the tufts — especially if you expect to eat on it. Crumbs will find their way into the tufting and are not always easy to get out. Round coffee tables aid circulation especially where there are many available seats as in this example. If not every seat can reach the table make sure there’s another surface at hand.
