Product reviews are very subjective. Based on the reviews of this boot I hoped for a great boot at a fair price. Instead I found the boot to be subpar in terms of comfort. They shoes were stiff and far too 'roomy'. My feet where floating inside them. I returned them immediately. I've had far more comfortable boots right out of the box.
Negative

Rated for 3+ but my 2 and 3 yr. olds both play with this. While the kids like playing with this, I like that it can grow with them. It has basic tools for younger children: rolling pin, presser with three tips, pizza cutter, safety scissors, play-doh knife. But it also has tools/items for older ones: bead making, art molds for pictures and "sand".The only con is the mat. It's cheap plastic. Sounded great on the box in the store, but ends up crinkled underneath them and not protecting the floor. Stick with using and old sheet or vinyl table cloth from the $1 store.
Positive

I bought the bed with the idea of using it during one week while my father was visiting. It fulfilled its purpose perfectly. It's comfortable, it inflates and deflates very quickly and it's pretty high. There are two reasons why I am not giving it a 5-star score: a) I used sheets and still, when I woke up, my back was sweating. I guess that it is a problem with all these beds that are made of plastic, but... that is a drawback. b) I haven't been able to fold it and fit it in the bag again, it's almost impossible.Anyway, overall, it's a great deal for its price. I would absolutely recommend it and the problems I pointed out are probably a problem in all air beds.

Positive
