A memory foam seat cushion with a center cutout that keeps the base of the spine free from direct contact with the seat. Weight distributes around the ring instead of through one central point. It fits most chairs, including office chairs, dining chairs, car seats, and wheelchairs, and the removable cover zips off for easy washing.

Everything You Need to Know
Every detail of the TENAX Donut Seat Cushion is worth knowing. Here's a closer look...
The Donut Shape Explained
+
- Standard flat cushions still create pressure at the base of the spine because the sitting surface covers the entire seat
- The ring shape removes that problem entirely by keeping the center of the cushion open
- All the support comes from the surrounding foam, not from the center
Memory Foam Support
+
- The foam compresses under weight and molds to the exact shape of the sitter
- Returns to its original shape when not in use
- Does not flatten out over time the way standard foam or fiber cushions do
Where It Works
+
- Office chairs for long workdays
- Dining chairs during meals or long table sessions
- Car seats on road trips or long commutes
- Wheelchairs for all-day use
The Removable Cover
+
- Zips off in seconds
- Machine wash cold and air dry
- Available in Gray, Blue, and Pink
Care and Maintenance
+
- Remove cover and machine wash cold on a gentle cycle, air dry
- Spot clean the foam base with a damp cloth if needed
- Do not machine wash the foam

Frequently Asked Questions
How does the center cutout actually help?
+
By removing the foam from the center, the base of the spine sits over the opening rather than pressing directly into the cushion. All the support comes from the surrounding ring, which distributes weight more evenly across the seated area.
Will it fit my office chair?
+
Yes. The cushion is sized to fit standard office chairs, dining chairs, car seats, and wheelchairs. It sits on top of the existing seat surface and does not need to be attached.
Does the cushion stay in place or slide around?
+
The base of the cover grips most seat surfaces reasonably well. For extra stability on smooth or leather chairs, placing it against the seat back helps keep it positioned.
How firm is the memory foam?
+
The foam is medium-firm. It compresses under weight and molds to the shape of the sitter, providing a balance of support and comfort. It is not overly soft or overly stiff.
Can it be used in a car?
+
Yes. It fits most standard car seats and works well on longer drives where sitting comfort is a concern.
Is the cover removable?
+
Yes. The cover zips off easily and can be machine washed cold and air dried. The foam base should be spot cleaned only.
Does the foam lose its shape over time?
+
Memory foam is more resilient than standard foam or fiber fill. It returns to its original shape after each use and holds up well with regular daily use.
How long does shipping typically take?
+
Orders are processed within 1–2 business days, and delivery typically arrives in 7–10 business days. Tracking information is provided once your order ships so you can follow its progress every step of the way.
Please read our Shipping Policy for more information.
What if this isn't right for me? What's the return policy?
+
Every TENAX product is backed by a 30-day return policy, giving the opportunity to try it and ensure it meets expectations. If it doesn’t feel like the right fit, returns are available within 30 days of delivery in accordance with the return guidelines.
