Don't you just hate how much stuff accumulates under your couch? Especially when you have small children. Well, we had a couple of loose legs on our love seat and Jim decided to fix all the legs by making a box frame around the whole base of the love seat. In doing so we realized that this keeps things from ending up under it, and makes for a strong base that can withstand children playing on it. So now we are considering this for our couch even though it still has strong legs.
A box base, great for support and great for keeping the clutter out from under the furniture. I only wonder why we didn't think of it earlier.

Make sure if you do this that the flap covers the base.
