May as well forgo the mattress and sleep on the slats!! Got this for a child and it’s shocking my child will sleep anywhere when tired but yet he was so uncomfortable he come to complain (very unusual for him) had to bunk with us and first thing we got a memory foam topper from dunelm which now makes it comfortable to lay on and he’s happy but you can still hear all the springs popping as you turn!! Not worth the hassle of returning.
