There are four main types: foam, gel, floatation and futons.
Most foam mattresses are made from layers of different densities of foam. By varying their density and depth, it’s possible to achieve different levels of comfort and support. They are particularly suitable for use with slatted bases and adjustable beds.
There are three main types of foam in use:
– A premium quality material, the natural type is derived from the sap of the rubber tree.
– Has a distinctive, resilient feel, is very durable and has anti-microbial properties that offer benefits to many allergy sufferers.
– Its natural elasticity means it recovers its shape immediately when pressure is removed.
– It also has very good point elasticity resulting in even distribution of pressure for independent support.
Visco elastic/Memory foam
– Responds to individual shape and pressure.
– Has good pressure relieving properties.
– Available in a variety of qualities and densities.
Polyurethane (PU) foam
– A synthetic, petroleum based foam with performance and price varying according to density and quality.
– It is widely used and very versatile.
– A new filling that is taking the bed market by storm.
– Can be combined with other materials e.g. foam.
– Ground-breaking technology known for its cooling thermo‑regulating properties.
– Delivers benefits such as breathability, pressure relief and body support.
– Support is determined by the amount of water used and the level of motion can also be varied.
– Known for their pressure free support and also good for allergy sufferers.
– Variable temperature heaters keep the bed warm and cozy.
– Made from layers of cotton or fibre wadding, which molds itself to the shape of the body.
– In Japan they are used on the floor with a mat underneath and rolled away during the day.
– In the UK, they are more often sold as budget priced sofa beds with slatted convertible frames.
