This is a comfortable mattress to sleep on.However it is suppose to be FIRM.When I sit on it it sinks about half way down. It is nice for now but how long will it last? You can also feel the springs when you set your hand on the mattress.Truthfully it feels like a refurbished one. My son bought a mattress yesterday from a local store and his is FIRM!! No sinking no springs.If this Nightland mattress really was firm I'd give it a five star.
