I bought this mattress about seven years ago in a king size and absolutely loved it. Then having to downsize, I was looking to replace my king with a queen, decided to try a nectar and had to return it, even try the superior cool mattress with an extra topper However, it just was not the same. Returned to that to then go back to this mattress, hands-down, the most comfortable mattress I have ever had. I get so many compliments on it from people that like a firm or like a medium it really does fit the needs for both. I tried this with a basic box springs, but could feel something was off so I did purchase the Lisa boxspring and it changed everything! It’s a must have with this mattress you will not regret it.
