This innerspring mattress is made with a heat tempered Bonnell innerspring built to withstand a tough cab environment. The innerspring is surrounded by resonated fiber pads to protect the comfort materials from abrading against the innerspring. The Damask top cover is quilted to two generous layers of foam. The bottom layer is a denser layer providing additional support and this is complimented with a much softer layer on top. The bottom fabric uses a non-skid material that prevents the mattress from shifting in the cab. This creates a very comfortable sleep surface, so you don’t have to sacrifice a good night’s sleep when you are away from home.
