This is a compilation of products that I have found useful for some patients
I have included advice related to their use
People with low back pain often find it more comfortable when sitting upright if the seat platform is tilted forward, so the front is approximately 2-3 inches lower than the rear.
If your seat cannot be adjusted then a large cushion or pillow can be placed across the back of the seat to achieve the same effect. Alternatively, a wedge cushion can be obtained from an orthopaedic supplier, the internet, or your therapist.
Below are links to good examples of this type of cushion from an established orthopaedic supplier
8 Degree wedge is suitable for a normal upright chair.Link
11 Degree wedge can be useful in a car seat which slopes backward significantly. Link
I have also included helpful advice related to their us
If you spend a lot of time at a desk, it is well worth considered acquiring a good, fully adjustable office chair. The most important qualities are that it has seat platform tilt and that you can adjust the seat and lumbar support height. Other factor can be the size, shape and firmness of the seat platform and lumbar support. Because of these variables, I advise my patients if they can to try a range of designs, before they buy.
I am lucky that quite near my practice I have a supplier called “Back Care Solutions” that stocks a good
range of chairs and other office ergonomic aids such as standing desks. Link
