I never noticed quite how bad my old mattress had gotten. It’s quite a difference when compared to a old sprung mattress and takes at least a couple of nights to get used to but then its so much better. Also using laptops in bed is much easier as they are held perfectly flat even when your lying next to them. One concern I had was the smell, but after a few days with the window open I can no longer smell it. Anyone who tries it mentions how different it is and how it makes you feel almost weightless as it holds you evenly due to the lack of springs. Definitely a better way to spend a 1/3 of my life!
