Many of us spend hours seated at a desk, in the car or at home. A seat cushion cannot change that, but it can make the seat more comfortable, and a cushion with a cut-out can take pressure off the tailbone.
This guide covers what the NHS says about tailbone and back pain, what to look for in an orthopedic seat cushion, and six cushions to compare.
General information, not medical advice; see a doctor if tailbone or back pain does not improve after a few weeks.
Orthopedic seat cushion basics
- For tailbone pain, the NHS suggests using a specially designed coccyx cushion when sitting, sitting with your lower back supported, and lying on your side to reduce pressure on the coccyx.[1]
- The NHS says not to sit for a long time if you have tailbone pain, and to see a GP if it has not improved after a few weeks of home treatment.[1]
- For back pain, the NHS says to stay active and not stay in bed for long periods.[2]
- CCOHS says a good chair seat should be comfortable and made of breathable materials, with no pressure on the back of the knees.[3]
- A cushion with a cut-out or U shape leaves space for the tailbone. A flat cushion adds comfort only.

What an Orthopedic Seat Cushion Can Do
An orthopedic seat cushion changes the surface you sit on. A cushion with a cut-out or U shape leaves space for the tailbone, and one made of foam or gel spreads your weight.
The NHS says tailbone pain is pain in the bone at the base of the spine, and that it may be worse while you are sitting, when you sit down or stand up, and when you bend forward.[1] Among the things that may ease it, the NHS suggests using a specially designed coccyx cushion when sitting, keeping good posture with your lower back supported, and not sitting for a long time.[1]
For back pain, the NHS says it usually improves within a few weeks, and suggests staying active, using ice or heat packs wrapped in a tea towel, and trying exercises and stretches.[2] A cushion adds comfort, and it does not replace those steps.
What Does an Orthopedic Cushion Look Like?
The video below shows what a few orthopedic seat cushions look like. Most are made of memory foam with a cut-out or U shape for the tailbone, and several of them are in our review section.
Features of a Good Orthopedic Seat Cushion
- Fill – Most orthopedic seat cushions are memory foam or a similar foam that conforms to the shape of your body. Some add gel layers or gel infusions for a cooler surface.
- Shape – A contoured, U-shaped or cut-out shape leaves space for the tailbone.
- Cover – A removable cover that you can wash, often with a zipper, is easy to keep clean, and a breathable fabric such as mesh or cotton is cooler.
- Non-Slip Base – It keeps the cushion from sliding on the chair or car seat.
- Seat Surface – CCOHS says a chair seat should be comfortable and usually made of breathable materials that limit heat and moisture buildup.[3]
