This has likely been done to death but I can’t find a topic that might cover it 
I’m on the hunt for a mattress upgrade. I have longstanding sciatica, joint hypermobility syndrome and am pregnant so fully expecting to come out the other side of pregnancy in worse physical condition than I started. Currently sleeping on an Ikea Hövag and it is just not good for my back anymore, to the point where I feel like I’ve been bulldozed overnight.
Willing to invest in something wonderful that will last me a long time!
