What are Seat Wedge Cushions Used For?

To answer that question, first, let's look at what wedge cushions are. Obviously, it’s a cushion in a wedge shape, usually about the size of a typical chair seat. Some are larger and more useful for car use. Others are a little smaller and adapt better to different types of seating.

Seat wedge cushions often have a cut-out in the back to prevent pressure on your tailbone. Some have a nonslip surface on the bottom, so the pillow won't slip around when you stand up.

Wedge cushions encourage good posture by tilting the pelvis forward and creating a healthy inward curve in the lower back. Good posture benefits the human body in many ways, from preventing spine and disc injuries to improving core muscle tone.

Car seat wedge cushions are terrific for shorter people who might have trouble seeing well when they drive. The cushion boosts their height, so they see better over the steering wheel and drive more comfortably and safely.

These gel and memory foam pillows can also be useful for anyone sitting in bed to work or read. Placing the wedge against the headboard and sitting on it prevents you from sliding onto your spine and creating a strain on your hips, back, and neck.

Wedge cushions can also be used while in bed to improve sleep quality during pregnancy, for people with sleep apnea, sinus infections, acid reflux, and certain eye diseases.

Do Wedge Seat Cushions Help with Back Pain?

Because they improve posture, wedge seat cushions can help with back pain due to bulging discs or muscle strain.

Slouching or failing to engage core muscles for back support can lead to discs bulging and pressing on nerves, resulting in sciatic pain.

Sitting on a wedge forces you to sit up straighter and creates a healthy curve in your lower back so that there’s less stress on discs. By sitting taller, you also engage abdominal muscles and prevent excessive strain on your back muscles.

If you sit too long while working or driving, using a wedge seat cushion will encourage you to take healthy breaks. You will stand and walk around to relieve muscle strain and straighten your spine because slouching becomes too difficult when using a wedge.

Will a Car Seat Wedge Work for Short Drivers?

Short drivers often struggle to drive comfortably and safely because cars aren't designed for their stature. The steering wheel may partially obstruct their view, and sun glare is a problem because the visor usually used to block it is too high to help.

A great answer to these problems is a wedged seat cushion for car use. The wedge raises a driver and still allows them to reach peddles and controls. Combining a wedge car seat cushion with a lumbar support can make driving easier, safer, and more comfortable for short drivers, especially for longer distances.

      5.  It helps you sleep more comfortably when you are pregnant, suffer from sinus infections, sleep apnea, or acid reflux.

     6.  Keeps you comfortable when sitting in bed to read or work.

FAQ Section

Do car wedge seat cushions work for bucket seats in a sports car?

Choose a smaller cushion size for bucket seats, but yes, they work just fine. Bucket seats can be especially hard on your back when you drive long distances, and adding a wedge can improve your posture. Better posture makes long drives easier.

 Are wedge seat cushions available in larger sizes for trucks and big sedans?

Pay attention to the overall size you choose if you drive a truck or have a larger car. There are wedge cushions that are oversize to fit better in these vehicles. They may not be as useful in your office chair but work great for driving more comfortably.

How much additional height can you get from a car wedge seat cushion?

Some cushions are 3 ½" at their widest part so that you will get about a 3-inch boost. If you don't need that much, look for a cushion that's 3 inches or even a little less. Your stature and car type should dictate how much cushion height you need.

Can I take a wedge seat cushion on a plane?

All airlines permit seat cushions to make your trip more comfortable. They generally don’t count it as a carryon piece. Some wedge seat cushions easily attach to your bag, so you don't have to carry them. Smaller pillows might be best for plane travel.
