If you are looking for a robust, durable & medium support 4ft Contract bed for a commercial business or organisation, the Dorset Crib 5 divan set from Kozee Sleep certainly fits the bill. Source 5 or Crib 5 contract divan sets & are designed specifically for commercial use in B & B's, hotels, hostels, holiday camps, boarding schools, care homes & student accommodation. Any mattress or divan set used in the above establishments must comply with strict BS7177 ignition fire regularity standards that go further than those required for domestic home use. The Dorset small double mattress has a micro quilted finish that secures the outer damask cover to the surface layers in a quilted pattern, reducing the chance of upholstery movement. Below the fillings is its interior, a robust open coil spring system that consists of hourglass shaped springs connected at the top & bottom by a spiral wire, known as a helical wire. To add strength to the mattress border, a thick 8 gauge rod-edge wire is attached around the perimeter of the spring unit & prevents border breakdown. This additional edge support allows you the use of the full width of the mattress without the sensation of rolling off. As the Dorset mattress is dual-sided, it is required to be rotated from head to toe & flipped over on a regular basis. This procedure will even out the wear & tear & extend the life of the mattress. Supporting the mattress is a solid top, platform style base that comes in depth's of 5" or 8" shallow bases with a choice of 7" plastic legs on castors or 8" wooden legs. Manufactured & tested to Crib 5 specifications, The Dorset small double Contract divan set is extremely durable & offers a medium support sleeping surface. Please note: Headboard is not included.
