Buying Guide
Helping you choose the right mattress or divan
Experts recommend that you should replace your mattress or bed every 8 years.
Open spring
The most widely used spring unit. There are at least 288 hour-glass shaped springs in a 4ft 6in mattress and 325 in a 5ft. All offer different levels of support.
Hand-tufted
Tension tapes are passed by hand through the mattress and secured by felt or wool buttons, securing the spring and surround springs.
Micro-quilted
A smoother surface than tufted. The raised pattern is created by stitching varying levels of fillings to the cover.
Ortho
A firm or extra firm mattress that provides extra levels of support. However, if you suffer from a bad back, you may find a memory foam mattress kinder to sensitive joints.
Pocket sprung
Luxurious individual pocketed fabric-linked springs independently compress and expand - continually adjusting to your body shape and weight.
Natural Latex
A natural rubber product that moulds to body contours and quickly recovers its shape. Ideal if you suffer from allergies or asthma as latex is naturally hypo-allergenic.
- Greater air circulation
- Better moisture control
- Optimum level of support moulds to your body's contours
- Inhibits dust mites to benefit asthma sufferers
Memory foam
With a unique feel, slowly moulds to the shape of your body by responding to body temperature and weight, relieving pressure points, helping to prevent restlessness. It helps to inhibit dust mites.
