Is the Everlasting Comfort Seat Cushion worth it?
A top pick in Office Furniture & Lighting on Amazon (#6 when we checked, Oct 6, 2026)
Worth it if It is worth considering if tailbone pressure is your specific problem and you want one memory foam cushion for an office chair, car seat, or travel. The U-shaped cutout, non-slip base, and washable cover make it suited to long sitting sessions.
Good to know: If you need a very soft cushion or exact fit for a particular seat, look for a model with a softer firmness or more clearly matched dimensions.
A memory foam seat cushion built for focused sitting support
By 4pm, a chair can feel less like a place to work and more like a pressure point. The Everlasting Comfort Seat Cushion addresses that with a 100 percent memory foam core and a U-shaped coccyx cutout. The foam conforms to your body, while the opening leaves space around the tailbone area rather than placing the full load directly beneath it.
That design gives the cushion a clear job: add support where a flat chair may feel unforgiving during long sitting. The listed medium firmness aims for structure without being described as hard, though buyer feedback shows that firmness is personal. For the right sitter, the result is a more supported position at a desk, in a car, or on another compatible seat.
Daily practicality matters too. The breathable cover comes off for machine washing on a gentle, cold cycle, and the non-slip bottom helps keep the cushion in place. The 17.3-by-14-inch, 3.15-inch-large cushion is also portable enough to move between an office chair and car seat. That means one support surface can follow the workday instead of staying attached to one room.
You get one portable memory foam cushion that can serve an office chair, car seat, airplane seat, stadium bench, or recliner. The removable washable cover also makes it easier to keep that one cushion in regular rotation.
Great for
- People who feel tailbone pressure during long desk sessions
- Drivers and commuters wanting portable seat support
- Travelers using office, airplane, stadium, or recliner seating
- Buyers who value a removable, machine-washable cover
Maybe not for you if
- You prefer an especially soft, sink-in cushion
- You need a precise fit for a seat with unusual dimensions
- You want a cushion with a different firmness feel
The Everlasting Comfort Seat Cushion is a sensible buy when tailbone pressure is the main reason you are changing seats. Its memory foam core, U-shaped cutout, anti-slip base, and washable cover give it a useful mix of support and everyday practicality. The large size is suited to many office and travel settings, though you should check the dimensions and consider the medium firmness before buying. For long desk sessions, commuting, or portable support, it earns its place by making one cushion useful across the day.
Amazon shoppers rate it 4.4 out of 5 across 105,448 ratings. That is their number, not ours.
