My son has just started watching Ben 10 and when we needed a new blow up bed I thought this would be fantastic.
We used to have a my first ready bed which is shaped to stop your child rolling out of the bed but this is a more grown up version and doesn't have that feature, consequently my 3 year old ends up half in and half out of the bed kept in only by the zip. However we wedge the zip side up of the bed against a wall and then he can't fall out!
I am pleased that this is a longer bed as at 3 he was too long for the my first ready bed when we used it with a pillow. However this bed does not have this problem.
I agree with the other review that the chair feature doesn't stay like that unless you have it up against a wall and are sitting on it.
Despite this, my son loves his new blow up bed and seems to find it comfortable enough.
