Got my mattress last month. Its amazing the sleep you get when you have a good mattress. The salesman recommended this mattress as I was looking for firm. I did not buy it and I went with another mattress. Well after that one didnt work out I used the sleep trail trade and upgraded to this Katrina mattress (as suggested by the salesman) and after a few nights I realized how well I was sleeping and the renewed feeling I had. Its amazing. Looking for a firm mattress? get this one!!! Love mine and thank you

Had to leave a review on this mattress. For years Ive had issues sleeping and sleeping well. The first few nights were a little weird as I thought is to be too firm. A few nights went by and then I slept all the way through the night and woke up feeling great. Ive had it for about 3 weeks and I have never slept better. I can think more clear even. its great! If you need or like firm mattresses this one has done it for me so far.
