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.
For a perfectly square table you may be tempted to use four matching pieces for a perfectly symmetrical look. However you can get a more intriguing look by using two pieces or groups one in each corner. Try a tall vase or lantern in one corner with a stack of two or three books in the other (and an airy sculptural accent on top).
