This mattress is simply way too soft. If you enjoy laying on a very soft mattress with no lumbar support then this is the mattress for you. It is also very difficult to move around as it is very heavy. I tried everything including buying an extra firm mattress topper but the problem persisted. It feels comfortable for the first couple of minutes until you begin to notice that your hips sink down into a hole (major lack of support) which causes a pulling feeling on your lower back. Very uncomfortable. Also no returns are accepted. Do not buy this mattress unless you like a mattress with very little back support.
