I debated whether to buy this or not as my son is 8 years old, but he loves Moshi figures so much and all his friends are into them too, that I decided to try it. Fabulous. He loves it and he has it in the living room and when his friends come over they sit in it together and play on the wii, etc.
He wouldn't be able to sleep on it as it wouldn't be long enough, but even if we play with it for six months it was well worth it as we got it on a bargain price. Great fun and lots of pleasure to be had with it.
