Description
The problem isn't you. It's the seat.
Car seats and office chairs are flat and hard exactly where your tailbone lands. An hour in, you start shifting. By the end of the day, you feel it every time you stand up.
It adds up fast. A daily commute plus a desk job is 8 to 10 hours a day on a surface that was never shaped for you. A folded towel isn't a fix.
The Ovva Seat Cushion gives your seat the shape it's missing.
- Tailbone cutout: a U-shaped gap at the back, so your weight spreads across your hips and thighs instead of your tailbone.
- Contoured memory foam: raised back and sides, shaped front for your thighs. Slow-rebound foam, not fluffy filler.
- Stays put: anti-slip bottom that grips car seats and office chairs.
- Breathable: soft velvet top and mesh sides.
Size: about 16.1 × 14.6 in (41 × 37 cm) and 2 to 3 in (5–7.5 cm) thick. A compact cushion for standard seats. Memory foam is measured by hand, so allow ±0.8 in (1-2 cm).

Product details
Made for: drivers, desk workers and anyone who sits for hours.
How it feels: medium-firm memory foam. You sink in a little, then it holds you.
How it works: the cutout keeps weight off your tailbone; the raised edges keep you from sliding forward.
Use it on: car seats, office and gaming chairs, kitchen chairs.
Size: about 16.1 × 14.6 in (41 × 37 cm).
How to use
Place it: put it on the seat with the U-shaped cutout at the back.
Sit into it: push your hips all the way back so your tailbone sits over the cutout. Keep both feet flat.
Use it everywhere: car, office chair, dining chair or gaming chair.
Give it a few days: memory foam feels firmer at first and softens to your shape with use.

The problems a flat seat creates
-
Pressure on the tailbone
The U-shaped cutout leaves space under your tailbone, so your weight rests on your hips and thighs.
-
Sliding into a slouch
A raised back edge and contoured sides keep your hips in place instead of drifting forward.
-
Hard, flat seats
Slow-rebound memory foam softens hard car and office seats and keeps its shape.
-
Shifting on long drives
Even support under your hips and thighs, so you are not constantly repositioning.
-
Same seat, every day
Take it from the car to the desk to the kitchen table. No new chair needed.
-
Stays where you put it
Anti-slip bottom that grips car seats and office chairs.
Up to 23× less than an ergonomic chair
Better sitting doesn't have to mean new furniture. One cushion goes on the seat you already have.

Questions, answered
Will it flatten out after a few weeks?
It's made of slow-rebound memory foam, which is designed to return to its shape after you get up. Watch the video above: press it down and it comes back to shape. And if it isn't for you, the 30-day comfort guarantee covers you.
Will it fit my seat?
It's about 16.1 × 14.6 in (41 × 37 cm) and 2 to 3 in thick (5–7.5 cm). That fits standard car seats and office chairs. It's a compact cushion: if your seat or your hips are wider than about 16 in, it may feel small.
Does it work on an office or gaming chair?
Yes. It sits on any flat seat: car seats, office and gaming chairs, kitchen chairs.
How long does shipping take?
Orders ship in 1–3 business days and arrive 6–11 days after you order, with free tracking. We ship to the 48 contiguous US states.
What if it's not for me?
If it's not for you within 30 days of delivery, email us at info@tryovva.com with your order number and a photo. We'll refund the product price. No need to send it back. Once per customer.
Isn't this just another seat cushion?
Most cushions are flat pads. This one is shaped: a tailbone cutout at the back, raised edges, and a thigh contour at the front, in slow-rebound memory foam.
Can I use it every day?
Yes. It is made for daily use: in the car, at your desk, or at the kitchen table.
Why not just get up and stretch?
Do that too. But if you drive or work at a desk, you can't stand up every 20 minutes. The cushion helps with the hours you do sit.
Is this a medical device?
No. Ovva cushions are comfort and posture accessories. They are not intended to diagnose, treat or cure any condition. If you have pain or a medical condition, talk to a healthcare professional.
One for the car. One for the desk.
