What Is the Best Wedge Seat Cushion?

Investing in a high-quality, ergonomically designed office chair can help with discomfort and pain but desk chairs are not one-size-fits-all. Your body is unique and you may have orthopedic issues that require a little bit of extra support. That’s where finding the best wedge seat cushion comes in. 

In this guide, we’ll teach you what a wedge cushion is and why you might consider buying one. We’ll also provide tips for choosing a wedge seat cushion and show you our top four picks. 

What is a Wedge Seat Cushion? 

Also known as a sitting wedge, a wedge seat cushion is simply a wedge-shaped pillow you place on top of your normal seat cushion. They’re typically made from supportive but pressure-relieving materials that contour to the shape of your body. In doing so, they may help relieve pain and stiffness while adjusting the position in which you sit. 

A firm wedge seat cushion helps distribute your body weight more evenly which takes some of the load off your spine. It’s a simple way to customize your office chair without having to shell out for an expensive model. 

What Are the Benefits of a Wedge Seat Cushion? 

With more people working from home than ever, the demand for home office comfort solutions has risen dramatically. When outfitting a home office you need to not only think about color schemes and decor, but high-quality furniture that gets the job done AND keeps you comfortable and supported throughout the workday. 

An ergonomically designed office chair with adjustable height, armrests, and lumbar support is essential but they’re not designed to meet the specific needs of every body. If you struggle with back pain or stiff muscles, adding a pelvic tilt wedge cushion might help.

Some of the potential benefits of wedge seat cushions include: 

• Relieving lower back pain
• Support for the pelvis
• Reduced joint pain and stiffness
• Improved posture 
• Reduced pressure on the internal organs
• Support for scoliosis sufferers
• Pressure relief for osteoporosis pain

If you suffer from any of the conditions above, the right wedge cushion could help. Keep in mind that they come in many shapes and materials, however, so it’s important to know what you’re looking for when you start shopping. 

Tips for Choosing a Wedge Cushion for Chairs

When shopping for a sitting wedge, there are three primary factors to consider: materials, size, and angle. Let’s take a quick look at each of these factors. 

Materials 

If you spend most of your day sitting, you’ll need to make sure your wedge seat cushion is made from materials that can stand up to extended use. Supportive materials like memory foam and latex are ideal because they conform to the shape of your body, delivering pressure-relieving support exactly where you need it. Consider the materials for the seat cushion cover as well – it’s ideal to find a cushion with a cover that’s removable and washable. 

Size

When choosing a wedge seat cushion, it’s important to find one that is appropriate for your size as well as the size of the chair. As long as you find your current chair comfortable in terms of size, you should be able to simply select a sitting wedge of the same width. If you’re not sure what size is best, measure the width of your hips and add an inch or two for comfort. 

Angle

A sitting wedge isn’t intended to solve all of your posture problems, but it can help you sit up a little straighter in your chair. Wedge seat cushions come in different heights which affects the angle of the wedge. They generally come in slimline angles up to 11 degrees. Choosing the right angle for your wedge cushion is usually a matter of preference.
