The mattress is fine.My issue was the delivery.The box it was wrapped in was
damaged a bit.A hole or gap was there.The fact that it had good plastic covering inside was important.So no rain got in.It was delivered by dpd out side against the front window,further away
from the sliding door.So if it rained enough water could have got in side the box.The dpd driver should have put the mattress inside the sliding door.The mattress is no where has heavy as the old one it replaces,easy to move around and change the sheets.The mattress
feels supportive,no noise from springs.My old mattress would tilt u too one side,this one feels level and balanced.The price is great too.This mattress solved my problems.
