Short Description

Modern mattresses are made in a variety of ways and from a variety of materials. They can be made using springs, latex, foam or water, and covered with layers of padding. A cover holds this padding in place and is fixed by tufting, deep stitching or microquilting, which gives a raised pattern individual to each manufacturer. The type and amount of filling or padding is reflected in the cost of the mattress. Mattress choice generally depends on personal preferences, physical needs and budget.

Models

FOAM
Cheap low grade foam mattresses are not resilient enough for everyday use.
High-grade foam gives good comfort (support and breathability) and durability. They are not very popular in Australia.

TEMPUR (slow recovery, memory or viscoelastic foam)
Viscoelastic foam is a pressure relieving material, originally developed by NASA to alleviate the incredible g-forces experienced by astronauts on takeoff. Viscoelastic foam mattresses "memorise" the exact shape and position of the body, giving the neck, back, shoulders and feet the comfort and support they need. The pressure of the user's body is evenly distributed across the mattress (therefore often used for prevention of pressure ulcers).
For general use you have to consider: the thicker the viscoelastic layer, the more you'll sink in - which makes it hard to move in your sleep and to sit up.

More Details

Manufacturers and chiropractors recommend replacing a mattress around every 10 to 13 years. A worn out mattress (obvious signs are e.g. dips or lumps, or if you wake up stiff) can also cause or exacerbate conditions such as back and joint pain, stiff ankles and knees as well as headaches. As a person ages, the amount of support required changes. A new mattress could prevent any future problems.

Factors To Consider

All pressure reduction products must be monitored to prevent 'bottoming out'. This occurs when the user's weight bears down so hard on the product material that it is flattened and the bony parts are pressed against the surface below the cushion or mattress. Where bottoming out occurs even with correct use (eg correct inflation levels), a different product may need to be considered.

Standards

Some assistive technology needs to meet Australian or other standards. Standards may relate to materials, manufacturing and installation. Products that meet Australian or international standards will have written certification. To find out if a product meets Australian Standards ask the supplier to show you the certificate.
