Old Crib Mattress
Put one of these in front of your couch and let the kids go nuts. Ours started as a safety net when the twins were babies. Now they jump off the couch on purpose. It's a trampoline, a nest, the roof of a fort. Our 6 yr old comes home from school and heads right to the mattress to jump out all his pent up energy.
We added an old ottoman/storage bench and this place is better than Gymboree. It's great for parents who find taking toddler twins to the playground both mentally draining and mortally dangerous.
Note: Target sells cheap crib sheets in colors like "cream" and "chocolate" to match your living room decor. "Chocolate", more commonly know as brown, doesn't show dirt.
