Bought a mattress on Black Friday. Whatever about the hype, we needed one, and it was 40% off. Was about 19 years since we got the last one, so we couldn't turn it anymore that made a difference.
Didn't spend enough time checking in advance and bought a memory foam mattress, was about twice as thick as the old one, a serious piece of machinery. Couldn't be turned, apart from end to end. Came two weeks later. The missus slept like a baby from day1. But I got a 'chemical' stink of it that she didn't get, and couldn't sleep on it. Had painted the room the previous week, so am not super sensitive, this just seemed to click with me in a bad way. Tried for few nights, but slept downstairs on the sofa cushions for best part of 2 weeks since.
Eventually though the actually store agreed to swap the mattress for another in store, didn't think they would tbh. Got a standard latex one. Sooo f**king glad to be rid of that other stinkpile, sleeping in the bedroom again (though was getting dangerous fond of the piece and quiet downstairs
) had already tried to get it sold online.
Anyway, moral of the story, think before buying a mattress, and seriously think about memory foam. They're damn warm too.
