Comfort that travels with you
This cushion isn’t just for cars; I use it in my aircraft too. The wedge design gives perfect support, improving posture and reducing fatigue on long drives or flights. The memory foam molds comfortably to your body, keeping pressure off your lower back and hips. It’s durable, portable, and fits easily in trucks, cars, or cockpits. Whether I’m behind the wheel or at the controls, it delivers the same comfort and stability. Bottom line: a multi‑purpose cushion that’s tough enough for the road and smooth enough for the skies.

Auto Seating
Purchased this cushion to use in my 2017 F-150 Ford truck (manual seat). The drivers seat springs seam to have become slightly weaker at the rear causing me to sit a little lower than I would like. Tried another full size seat cushion, but it raised me too high for driving comfort. This smaller wedge shaped cushion is absolutely perfect, and puts me at exactly the elevation I find works best. It stays in place, is comfortable, and resolves the issue I purchased it for. Great quality, great vendor, great purchase experience from Amazon. [Review submitted by Marianne's husband]

Works well for purpose intended
I bought this because I’m pretty short at 5’5” and my car seats are leather so I slide down constantly and have a hard time seeing everything around me. This helps so much and I feel like I can see everything now. It doesn’t slide down my seat at all and because it’s a wedge, it meets with my seat pretty well so my legs aren’t killing me. I like it!

Cushion for driving comfort
I started using this seat cushion in my truck because my lower back would ache after long drives. The wedge shape lifts me just enough to see better over the hood, and it feels more supportive under my legs. The memory foam is firm when I first sit down, but it softens up a little as it warms, which makes it more comfortable on longer trips. On my commute, I’ve noticed less stiffness when I get out, and the pressure on my tailbone feels reduced. The cover has a mesh texture that keeps it from getting too warm, even in the afternoon sun. I also like that it doesn’t slide around when I’m getting in or out of the seat. I tried moving it to my office chair one day, and it worked just as well there. The height boost takes a little getting used to, but now it feels odd driving without it.

Needs more height and support.
Not as firm as needed.

THAAANK YOU
It's been 12 minutes... and I already know I've made the right purchase. I have been suffering severe low back, hip, and neck pain for months. This wedge seat finally helps me achieve the posture I've needed all this time... and instead of creating more pain, I'm starting to feel the release! THAAANK YOU

Compense bien le creux du siège de voiture, petite anse pour le porter et assez dense.

I am sort. The seat on my car, has a deep like v on the bottom back. I start to have pain and discomfort, and I put a pillow I had at home. Things were great. But after 1 month, same discomfort again. So I decide, to order something like a pillow from Amazon. I did not believe, that what I choose, is going to work. But YES works. I great. No pain. NO discomfort, and I drive every day. So far has kept his shape. I love it. I recommend this pillow , to every one that needs a boost, on their car seat . Thank you. Great product. Worth the price I paid. Thank you.

Still holding its form after months, love it, the wedge keeps you higher while not putting pressure on the bottom of your thighs, especially for short people. Will buy again.
