Query: Childs sleeping cot

Loved it till my son laid on it and the huge bar in the middle was very uncomfortable. None of the reviews I read before purchasing mentioned it. It's a very nifty cot, but if my son can't sleep on it without back pain the next morning then what's the point. I guess for only $29.99 I figured something had to be off since most cots started around $70.00.
