Ordering from The Mattress Warehouse was a great experience. After placing my online order I received a follow up call from their office (unfortunately I cannot remember the lady's name but she was very professional and delightful) to confirm my order and double check my mattress choice. The delivery team, Mboh and Lwazi, were also very professional and efficient. Well done to everyone involved.

Beds with a firm comfort rating are great for certain sleepers. Firm mattresses give way a lot less under body weight, creating a firm and solid platform that allows perfect spinal alignment. People who like to sleep on their backs and stomachs will greatly benefit from sleeping on a firm mattress.
