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.
Keep in mind that with most glass tops — if they are not inset — you’ll see a green tint on the sides. You can order a speciality glass that doesn’t have this tint but it’s more expensive.On the other hand perhaps you want your space to look cozier (and you need some storage). Stash baskets trunks and old suitcases under simple legged coffee tables to ground spaces that are otherwise too open.
