The holes did not line up on the mesh base, it was a nightmare trying to get them to but it hasn't been made correctly so they would just not line up. I was about to call Wayfair and ask for them to come and collect the bed immediately but we'd spent time taking the old bed down and putting this one up so there's no way we were spending even more time taking this down and putting the old one back up!! In the end we just had to put the mattress on and hope that the base doesn't move about or make a noise. Very disappointing :(
