Absolutely fabulous - but ....
This mattress was everything it promised: I didn't over-heat and remained cool all night. Neither was it a 'trench' - where you sink in and can't turn over without a struggle. Sadly though, I have to return it as, due to my disintegrating joints, I found it too firm. Don't let this put you off. I'm what the medical profession call an 'interesting case', which is not a good thing to be! So I'm not a typical customer as far as mattresses go. I rate Leesa customer service 5 Star - helpful and very efficient.
