The Purple Ultimate Seat Cushion is a popular seating accessory designed to provide comfort and support for various sitting needs. It is manufactured by Purple, a company known for their innovative and unique cushioning materials. Here is a detailed analysis of the Purple Ultimate Seat Cushion:

Material and Construction:

The Purple Ultimate Seat Cushion is made from a combination of two primary materials: Hyper-Elastic Polymer and polyurethane foam. The top layer is composed of the company's proprietary Hyper-Elastic Polymer, which is a flexible and durable material designed to provide superior support and pressure relief. The base layer consists of high-quality polyurethane foam, which adds an extra layer of cushioning and support.

Ergonomic Design:

The seat cushion features an ergonomic design that aims to promote proper posture and alleviate pressure on the hips, tailbone, and lower back. The cushion has a contoured shape with a raised back edge, which helps to maintain the natural curvature of the spine and reduce strain on the lower back.

Pressure Relief:

One of the key features of the Purple Ultimate Seat Cushion is its ability to distribute weight evenly and relieve pressure points. The Hyper-Elastic Polymer material has a grid-like structure that allows it to flex and adapt to the contours of the body. This helps to alleviate pressure on sensitive areas, such as the tailbone and hips, by evenly distributing the weight across the cushion.

Temperature Regulation:

The Hyper-Elastic Polymer material used in the cushion has excellent temperature regulation properties. It features an open-cell structure that promotes airflow and prevents heat buildup. This helps to keep the seating surface cool and comfortable, making it ideal for extended periods of sitting.


The Purple Ultimate Seat Cushion is designed to be versatile and can be used in various seating situations. Whether you're sitting at a desk, driving a car, traveling on a plane, or attending a sporting event, the cushion can provide added comfort and support. It comes with a non-slip bottom to ensure that it stays securely in place on different surfaces.

Maintenance and Care:

The Purple Ultimate Seat Cushion is relatively easy to maintain. The cover is removable and machine-washable, allowing for convenient cleaning. The cushion itself can be spot-cleaned with a mild detergent and warm water. It is recommended to air-dry the cushion after cleaning.

Dimensions and Portability:

The cushion has a compact and portable design, making it easy to carry around. It measures approximately 18.5 inches in width, 14 inches in depth, and 3 inches in height. This size is suitable for most standard chairs and seats.

Customer Reviews:

Overall, the Purple Ultimate Seat Cushion has received positive reviews from customers. Many users praise its comfort, pressure-relieving properties, and ability to alleviate back pain. The cushion's durability and temperature regulation features are also well-regarded. However, some users with specific needs or preferences may find the cushion too firm or not supportive enough for their liking.


Many customer reviews will also note that this particular cushion is massive in size and this may not fit all chairs or seats comfortably. The dimensions are a staggering 21.75" x 18" x 2.5" and weighs 7.3 lbs. For me personally I use a chair with a very large flat surface (Herman Miller's Embody) and it works perfectly for me.

The second issue which was also noted by other users on their websites review, and i do find as a minor annoyance is the cushion often slowly slides forward causing you to have to stand and scoot the cushion back into place. I found over my time with the cushion that the adjustment was needed 3-4 times an hour, which isn't too bad considering you should be getting up about that often anyway.

The Final Verdict:

I would say I am overall very happy with the product, and the tailbone pain i have been battling with for years has actually got some much needed relief. I would give this product 8 thumbs up, only leaving the 2 thumbs down due to the sliding of the cushion.
