They sell something like this at most any store like walmart kmart etc for around 30 apiece but if you take two in a corner you get quite a bit of room plus i like the legs being so small so my office chair fits under it easily. They probably make them bigger and nicer but toss some fabric ontop and you cant even tell what is under there. Here is one that is rated at 2500 pounds if you are worried about it being flimsy.
