Extra beds ordered for my daughter, 3 years and a half. Tried during the holidays, it is first proved too tedious to inflate the mattress provided with the inflator; I had to inflate it by mouth. In the middle of the night, the mattress was completely deflated as he had been properly plugged. In the second use, the mattress is again deflated. This is unfortunate because the cover is very pretty and highly appealing to my daughter. I'm really disappointed.
