The 2 Temps Mattress available at the Original Mattress Factory offers a firm version and medium version which makes it very versatile.
Sleep & Co ‘Hybrid’ Mattress (Discontinued)
The Sleep & Co ‘Hybrid’ Mattress is comfortable with a nice ‘light’ feel. It absorbs body weight well. The spring system also provides very good spinal support.
The Comfyaz Mattress (Discontinued)
The Comfyaz Mattress has excellent spinal support and although it is quite firm, it still has a nice comfort layer on top.
