WOW is all I can say about this mattress!!!!! This mattress feels like a high end luxury mattress brand and it comes in a box what all can you ask for. I got this mattress because the one I had was super hard and I had to sleep on my back all the time. I am a stomach sleeper so I wasn’t getting any good sleep. The first night I slept on this FANSACE mattress I had the best sleep it is super comfortable and soft but has enough support for your back and neck. I slept through the night the first night I got this and it wasn’t even at its full potential. PLEASE DONT WALK RUN!!!!!!! Very great price and well worth it. If this isn’t the review yall wanted or needed to stop you from getting this mattress I am here to say please purchase it.

My old hybrid mattress was done. I got tired of falling into a valley. I did a lot of searching and found this one. I love the medium firm. Its firm enough to support without feeling like a board. Good edge support so you can sit on it without sliding off. I also like the black color! I got the 16 inch and have it on a box spring on the floor. Plenty high enough without a frame. The slat frames tend to separate and can cause your mattress to sag in between. It also has nice thick handles on the sides.

The mattress we received has about a 2 inch area of “memory foam at top. Nowhere close to the thickness in the picture. It says there is foam around bottom edge but we feel coils and nothing between the cloth and coils. Contacted Amazon cause we are not sure if we got correct mattress. They have zero clue. Seems very poor quality not as described at all.

I found this to be a great mattress. It is not too soft but firm enough. Great on the back & those who sleep on their side. The materials appear to be of good quality. Very pleased
