I love love love this mattress!!!! Hubby and I were both having back pain in our plush $3000 kingsdown..... bought this bad boy and we are in love!!!! It's firm!!! Not like sleeping on a floor...but like if the floor was soft and just what your spine needed.  Lol I recommend it 100%. My friend came over and laid in it for 20 mins...went home and orderd one...after her Endy came and was too soft!
