An orthopaedic mattress is a type of mattress that is designed to provide support and alleviate pressure on the body's joints, particularly the spine, hips, and shoulders. The goal of an orthopaedic mattress is to promote good spinal alignment and help maintain the natural curvature of the spine during sleep.
(this is the goal of every mattress, the term orthopaedic has been added or implied to many mattresses in the thirty years I have been in the business. It is meant to be used as a sales tool. Some manufacturers even pay health organizations to endorse their mattresses)
Orthopaedic mattresses are typically made from high-density materials such as memory foam, latex, or pocket springs, which can offer a more firm (not true) and supportive feel than traditional coil mattresses. These materials can help distribute body weight evenly and reduce pressure points that can cause discomfort and pain. (True, with latex on balance performing the best)
Orthopaedic mattresses are often recommended for individuals who suffer from back pain, joint pain, or other musculoskeletal conditions. However, it's important to note that not all orthopaedic mattresses are created equal, and the level of support and firmness can vary depending on the materials used and the specific design of the mattress. It's always a good idea to test out different types of mattresses and consult with a healthcare professional before making a purchase. (I've never met a healthcare professional that has anything but a rudimentary knowledge of mattresses)
