The first area is separated a bit from the rest of the basement by partial walls with a large opening. This is what we use as a barrier between a play area and the jump around rowdy area. The play area houses a loveseat, bowl chair, arm chair, TV, Wii, 2 Ikea Trofast shelving units, a train table, bookshelf of children's books, cardboard blocks, and some toys. Okay, a lot of toys. Too many toys.
We use the train table to contain messes - train tracks, of course, marble runs, play-doh, coloring, etc.
So we went with this inflatable pool instead that my friend scored on clearance and it fit the area soooo much better. Since it still didn't have enough balls we put 2 Ikea mattresses in the pool. Most of the pool has twin mattresses in it with the balls filling the remaining space to the brim! Even the oldest kids in the house can jump and slide on the mattresses into the ball pit!
The crash pad is a really big deal in our house! All 6 of the kids here have special needs - and the sensory output the crash pad provides is a great calming tool. I found this enormous and really nice bean bag chair on Craigslist for $30 - it fits 2 adults and comes with an ottoman!
The kiddos jump from the trampolines onto the bean bag chair - we have tumbling mats set up behind it to protect the kids (and the walls). For a couple of the kids simply sitting in the bean bag chair and having it snug around them is calming - the pressure helps.
The OT room is frequently a mess but at least that mess is downstairs, out of sight, not in my living room! With so much cold weather in Minnesota I love that there is still a place the kids can go to burn off energy and be active.
We rotate the equipment/toys often to keep the area open enough for playing (and keep items in the storage room when not in use). We can put items away to make room for the bouncy ball that you sit on and use to bounce across the room. A couple of the kids are a big fan of the mini punching bag and basketball hoop.
A couple of the mini tramps can be put away to make room for an indoor tent and tunnels - which is Bruce's favorite! The Candy Land Rug Game can be played here or an elaborate train track can be set up. The girls house their scrapbooking stuff down here - which is awesome because it makes so much mess in their little bedroom.
The girls have little clubhouses/hideouts in their playroom closet and the storage closet, complete with reading lights and bean bag chairs. Great for when they need some quiet alone chill time in a house always full of people and noise.
