I have one of these Flippin' Fun Futons and if I had more cage space I would buy another. My guinea pigs love their futon! When it is not being laundered, they take turns resting on it. It is the favorite spot in the cage. I use the potty pad in it until that gets smelly (I'll probably order an extra Potty Pad or two from this site sometimes soon) and then let them use the futon with just the cover until that needs washing, then throw all the fleece components in the wash with my Fleece Flipper covers and uhaul liners - so easy! It's easy to assemble and adjust and the fringe curtain and top provide plenty of security to make it a favorite napping place. I've assembled it with and without the arms for variety. The three exits (right, left, and front) allow for quick escapes so no one gets cornered in it. My piggies even run laps through it at times. It's a big hit with my piggies and I love taking photos of them lounging in it. Sometimes I'll see a little pair of feet sticking out from under the fringe, sometimes a cute piggy nose. Lots of fun for them and for me!
