About a year ago i had bought a bed from the one on marks and the bed didn't fit me so my back started to hurt. I started looking for new bed and i went to the one on Serene and I am so glad they have Chris working there he is amazing! He took his time to find me the bed that would best work for me and since i have had the bed i have no issues! Also the delivery guys were really nice fast and efficient. I would recommend this mattress firm and Chris of course!
