Real cushion. Real seats.
Short clips of the actual cushion.
Your chair is pressing on the wrong spots.
Hard seats push your weight straight onto your tailbone and lower back. After an hour, it aches. After a long drive, the pain can shoot down your leg.
OrthoNest lifts your tailbone off the seat, supports your lower back and spreads your weight evenly - so you can sit through the workday, the drive or the movie without shifting every five minutes.

Made for the seats you can't avoid
Sit down without bracing for it
The coccyx cutout leaves an open space right where your tailbone meets the seat, so it carries none of your weight.
✓ Open cutout - no pressure point
Hours behind the wheel, less leg pain
Thigh channels and an even foam base keep pressure off the hips and the back of the legs - the areas that ache and go numb on long drives.
✓ Non-slip base for car seats
Better posture without thinking about it
The built-in backrest fills the gap behind your lower back, so you stop slumping forward by mid-afternoon.
✓ 12.6 in / 32 cm backrest
Foam that doesn't go flat
Memory foam shapes to your body, then slowly recovers when you stand up - day after day.
✓ Memory foam coreReady in three steps
It ships vacuum-rolled. Open it and let it rise - it reaches full shape in 24-48 hours.
Set it on your seat with the backrest against the chair back and the cutout to the rear.
Let your lower back rest on the backrest. That's it.

Your first month
Unroll and let it rise. The first sit feels noticeably softer under the tailbone.
Your body gets used to sitting back against the support instead of perching forward.
It's simply part of your chair, car and routine - and you notice when it's not there.

Good to know
Will it fit my chair or car seat?
It measures 17.3 x 16.5 in at the seat with a 12.6 in backrest, which fits most office chairs, dining chairs, car and truck seats and standard wheelchairs. Check your seat is at least 17 in wide.
It arrived flat. Is that normal?
Yes. It ships vacuum-rolled to protect the foam. Unroll it and give it 24-48 hours to reach full shape.
Does it help with tailbone or sciatica pain?
It's designed to take pressure off the tailbone, hips and lower back while you sit, which is what many people with these problems look for. It's a comfort product, not a medical treatment - if you have ongoing pain, talk to your doctor.
Will it slide around?
The base is non-slip, so it stays put on most car seats, office chairs and dining chairs.
Will it get hot?
The velvet-soft cover is breathable, so air moves through instead of trapping heat against your back.
Is it too firm or too soft?
Memory foam softens slightly with body warmth, so it feels supportive at first and molds to you after a few minutes of sitting.
How do I keep it clean?
Spot-clean the cover with a damp cloth and mild soap, then let it air-dry. Don't machine-wash the foam.
How long does shipping take?
Orders are processed within 1 business day and usually arrive in 7-15 business days anywhere in the US. Shipping is free to all 48 contiguous states. You'll get a tracking link by email.
What if it's not right for me?
You're covered by our 30-day money-back guarantee. Contact us within 30 days of delivery for a refund.
My favorite chair is still in good shape, but the seat padding has seen better days lol. I like that I can add a supportive cushion instead of replacing the whole thing. The dark gray fabric also looks pretty nice with the rest of the room.
I catch myself slouching when I'm at the computer for too long. Having a little support behind my lower back reminds me to sit back in the chair instead of leaning forward all afternoon. I still get up and stretch, but I like the extra support.
What I like is being able to use the same cushion around the house. I can move it from my desk chair to the kitchen without having to rearrange anything. Pretty convenient for everyday use.
I don't really like cushions that feel like you're sinking all the way through them. I prefer foam with a little structure to it. The contoured shape is especially nice because it doesn't feel like an ordinary flat seat pad.
I love sitting in my favorite chair with a book, but the seat isn't as soft as it used to be. I like the gentle support and the way the cushion follows the shape of the chair. Nothing fancy, just a more comfortable place to sit.
I've tried using a small pillow behind my back, but it always seems to slide around. Having the seat and backrest together is much more convenient. One piece is just easier to set up.
I never realized how much pressure a hard chair puts on my tailbone until I started paying attention to it. The open space at the back of this cushion is what caught my attention. I like that the design gives that area some room instead of just adding another flat layer of foam.
Long drives usually leave me shifting around in my seat trying to get comfortable. I like the contoured shape and how it supports more than just the seat bottom. It's a practical thing to have in the car.
I work from home and didn't really want to spend money on a whole new office chair. This style of cushion is a nice way to make my existing setup more comfortable. I especially like having the back support built right into the seat.
I spend a lot of time sitting at the kitchen table, and that wooden chair gets uncomfortable pretty quickly. I like having some cushioning under me and support behind my lower back at the same time. It makes sitting down with my coffee a lot more pleasant.
