I'm lying in bed on a 3 year old £600 mattress and I just want to sleep on the floor, it's absolutely awful (I think it's an Emma or Simba) I've had back pain for a while and I'm positive it's due to this bloody mattress. As soon as I'm in bed I sink down and roll into my partner, boiling hot all night. I need a hard mattress but can't find one online.....
