Can anyone recommend a good mattress? As cheap as possible TBH. I can’t really afford to replace but current one is killing my back so needs must. I’m single so don’t need to worry about rolling into a partner or different firmness needs. I don’t actually know what firmness I need. I’ve tried lying on beds in bed shops but can’t really tell from that what is going to be right for spending 8 hours a night on. Current mattress was a groupon memory foam and was great for about 4 years but the craters my body creates have stopped disappearing when I turn the mattress and it’s uncomfortable as soon as I get in.
Also is now a good time to buy or are there likely to be sales after Xmas?
