Worst mattress I have ever had, AVOID AT ALL COST, After having the mattress for 18 months I found that it started sagging and was very uncomfortable. Even after returning from work it still sags and dose not go back into shape. I have turned the mattress over many times over the time I have had it and rotated it like it says. Now the mattress is not fit for purpose, expensive mattress with very disappointing results. I'm waiting for a reply from Dreams. I will update my review when I get a response, until then this mattress is only fit for the rubbish dump. I will stick it in the spare room and buy a old fashion mattress for the time being. Not sure if I could trust buying another memory foam mattress ever again.
