I ordered 5 of these for my kids bunk beds.  I ended up having to sleep on one for a few weeks until my queen mattress came in.  It was definitely not the most comfortable mattress - you could feel the springs at times, but for kids I think it is okay for the price.  One of the mattresses arrived with rust stains on it, but I called Wayfair and they immediately sent a new one - no questions asked.  I didn't even have to return the rusted one.
