That's awful. I hope you got anice one now. It's surprising people don't realise the importance of the right mattress. This time last year I got into the bad habit of sleeping on the sofa in front of the telly, then one morning I wake up with, I learned, sciatica. I never felt such crazy excruciating pain. It took weeks of various pain meds until it eased and I could get up...all from sleeping awkwardly on the sofa🤕🛌
