Ortho Support Mattresses: The Facts

What Is An Orthopaedic Mattress

An orthopaedic mattress is designed to support the spine, skeleton, and muscles while you sleep. The term "orthopaedic" generally indicates extra-firm construction, though the exact meaning varies between manufacturers.

These mattresses are built to prevent the body from sinking unevenly, which can create pressure on the hips, shoulders, and lower back. The goal is to keep the spine in its natural alignment throughout the night.

Construction

Orthopaedic mattresses come in two broad categories:

• Spring-based: these use either independent pocket springs or multi-pocket springs to provide firm, targeted support. Pocket spring versions are preferred because each spring responds to pressure independently.
• Latex-based: considered the best option for orthopaedic support. Natural latex is resilient, moulds to the body under pressure, and returns to its original shape when the pressure is removed. Mattresses with natural fillings like coconut fibre, wool, and horsehair tend to be more durable.

Spring orthopaedic mattresses without pocket springs are now considered less effective. While they are cheaper, they do not provide the same level of targeted support.

Who Benefits Most

Orthopaedic mattresses are best suited to:

• People who prefer a firm sleeping surface
• Back sleepers, as the firm construction keeps the spine straight
• Anyone with lower-back pain who has been advised to try a firmer mattress

If you sleep on your side, an orthopaedic mattress may feel too firm, as it does not allow the shoulders and hips to sink enough for proper spinal alignment. A medium-firm mattress is generally a better choice for side sleepers. See our firmness guide for more detail on matching firmness to sleeping position.

Benefits

• Long lifespan: orthopaedic mattresses typically last 10 to 12 years, compared with 5 to 7 years for standard sprung mattresses.
• Spinal alignment: the firm construction supports the natural curve of the spine and prevents sagging.
• Allergy options: latex orthopaedic mattresses are hypoallergenic and resist dust mites.

Care And Maintenance

• Place the mattress on a flat, firm surface or a purpose-built orthopaedic slatted base.
• The mattress should extend at least 15 cm beyond your height.
• Rotate head to foot every six months to promote even wear.
• Check regularly for sagging, as a sagging orthopaedic mattress no longer provides the support it was designed to deliver.
