Why Nothing Has Worked
It's Not That You Haven't Tried. It's That Every Cushion Still Touches the Spot That Hurts.
More padding covers the pressure. A softer cushion softens the pressure. But as long as something is still pressing on your tailbone, the pain keeps coming back.
How the SitWell Works
More Padding Softens the Pressure. The SitWell Removes It.
Most cushions add softness between you and the chair. That helps at first — until the foam compresses and your tailbone is right back on the hard surface underneath. The problem was never that you needed more padding. The problem was contact.
Your tailbone is a small, bony structure that helps bear your weight when you sit. When a chair keeps pressing directly against a painful tailbone, no amount of material on top solves the problem. It just presses softer.
The SitWell's open coccyx cutout removes contact entirely. Your tailbone sits over open air — nothing touching it at all. Your weight is redistributed onto your thighs, sit bones, and the surrounding tissue that can actually handle it. The contoured lumbar back supports your lower spine so you're not slumping forward to escape the pressure.
It doesn't mask the problem. It changes the mechanics of how you sit.

What the SitWell Does
Built-In Features
- Open Coccyx Cutout
- Contoured Lumbar Back
- High-Density Memory Foam
- Waterfall Front Edge
Why This Is Different
Donut cushions still press on the tailbone with their rear ring. Generic foam cushions flatten within days. Gel cushions don't redistribute weight. The SitWell removes contact with your tailbone completely and holds its shape through months of daily use.
Merck Manual — Wedge/U-shaped cushions allow weight to be borne by the ischial bones while the coccyx sits over the empty area
What Changes
What It Looks Like When Sitting Stops Being the Problem
You'll notice it at dinner, in the car, at church, and in your recliner.
Benefit #1
Zero Tailbone Contact. Immediate Relief.
The open coccyx cutout means nothing is pressing on your tailbone. Not foam. Not gel. Not a ring. Your weight shifts to the areas that can handle it while the tailbone sits over open air. Most customers notice the difference the first time they sit down.
Benefit #2
It Won't Flatten Out After a Week.
The number one complaint about seat cushions is that they go flat. The foam compresses and suddenly your tailbone is right back on the hard seat underneath. The SitWell uses high-density memory foam that holds its shape through months of daily use — not the cheap stuff that gives out after a few days.
Benefit #3
Take It From Room to Room. Chair to Chair.
Recliner, dining chair, car seat, church pew, doctor's office, wheelchair. The SitWell fits standard chairs and travels with you. Keep one at home and one in the car, or carry it wherever the day takes you. 17" × 16" fits where you need it to.
Benefit #4
Lumbar Support Built Right In.
Most coccyx cushions are just a seat pad. No back support. So you relieve the tailbone but your lower back is left unsupported and you end up slumping forward. The SitWell includes a contoured lumbar back that supports the natural curve of your spine. One cushion. Two problems solved.
Inside the Cushion
What's Actually Doing the Work
Every feature solves a specific problem that other cushions don't.
◉
Open Coccyx Cutout
Zero Tailbone Contact
The back of the cushion is deliberately open so your tailbone sits over air — nothing touching it. This is the same off-loading principle recommended by clinical sources for coccyx pain: don't cushion the pressure, remove it.
◐
High-Density Memory Foam
Holds Shape for Months
This is not the foam that goes flat after a week. High-density memory foam maintains its shape and firmness through hours of daily use. Your tailbone stays suspended over the cutout — not sinking through compressed foam back onto the chair.
✦
Contoured Lumbar Back + Side Bolsters
Full Seated Support
The lumbar back supports the natural curve of your lower spine so you sit upright without straining. Wraparound side bolsters cradle your hips and reduce pressure on the sit bones — so relieving your tailbone doesn't just move the pain somewhere else.
🜄
Waterfall Front Edge + Ventilation Channel
Comfort for Long Sits
The waterfall front edge eliminates pressure behind your thighs — no numbness or tingling during long sits. The ventilation channel keeps airflow through the cutout so you stay cool and dry whether you're in the recliner for two hours or in the car for three.

The Science Behind It
From Rehabilitation Research to Your Living Room
The principle behind the SitWell didn't start in a cushion factory. It started in a rehab center.
Why Adding More Padding Never Worked — and What Rehabilitation Centers Have Known for Decades
Most people think tailbone pain means they need a softer seat. More foam. More gel. More padding between them and the chair.
Rehabilitation centers figured out a long time ago that this doesn't work. A study from Rancho Los Amigos National Rehabilitation Center — one of the most respected rehab facilities in the country — documented a different approach: instead of cushioning the pressure, remove it entirely.
They used foam cutout cushions that recessed vulnerable bony areas so there was zero direct contact. Pressure mapping confirmed it — the tissue over bony prominences was completely off-loaded.
That's the same principle behind the SitWell. The open coccyx cutout eliminates contact with your tailbone. The high-density foam around it redistributes your weight to the areas that can handle it. One cushion. One principle. The one that actually works.

The Principle
Clinical Support
- Rancho Los Amigos Rehab Center Study
- Merck Manual Recommendation
- Pressure Mapping Evidence
- Systematic Review of Coccydynia Treatment
What This Means for You
Donut cushions can actually make tailbone pain worse — clinical sources note the rear ring can press directly on the coccyx. Generic foam cushions compress until the tailbone contacts the chair again. The SitWell was designed around the one approach that rehabilitation research supports: remove contact completely.

They Tried One More Cushion. It Was the Right One.
Stories from customers who know what it's like to dread sitting down.
I sat through Christmas dinner for the first time in two years
★★★★★"I've been through three different cushions in the last year. All of them went flat or moved the pain to my hips. This is the first one where my tailbone actually doesn't touch anything. I made it through the whole meal — dessert and all. My daughter couldn't believe it."
Patricia S. Verified Customer
Finally comfortable in my own recliner again
★★★★★"My recliner was my favorite spot for 15 years and the last year and a half it's been miserable. I was lying on my side just to watch TV. This cushion gave me my chair back. I use it every single evening and the foam hasn't gone flat."
Robert H. Verified Customer
Church on Sunday is comfortable again
★★★★★"Those pews are hard as a rock and I was getting to where I couldn't sit through a full service. I bring the SitWell every Sunday now. It fits right on the pew and nobody even notices it. I sit through the whole thing without shifting around."
Carol D. Verified Customer
Bought it for my mom — she uses it everywhere
★★★★★"My mom kept standing up at family dinners and I finally asked her why. She said her tailbone was killing her but she didn't want to complain. I ordered this for her and now she takes it from the kitchen to the car to the living room. She says it's the first cushion that didn't go flat on her."

Your Questions, Answered Honestly
Everything You Want to Know Before You Try It
Will this fit my chair?
The SitWell measures 17" × 16" × 14.5" and fits standard dining chairs, recliners, gliders, car seats, wheelchair seats, church pews, and office chairs. If your chair has a flat or gently contoured seat, it will fit. Deep bucket seats (like some sports cars) may not be ideal, but standard car seats and SUV seats work well.
Will the foam flatten out?
This is the most common complaint about seat cushions — and the reason we use high-density memory foam instead of standard foam. Standard cushions compress within days and your tailbone ends up right back on the hard seat underneath. The SitWell is designed to hold its shape through months of daily use. That's the whole point — if the foam goes flat, the cutout doesn't matter anymore.
How is this different from a donut cushion?
Donut cushions have a hole in the center but a ring all the way around — including behind the tailbone. Clinical sources note that the rear ring of a donut cushion can actually press on the coccyx or lower sacrum and make tailbone pain worse. The SitWell has an open cutout at the back — nothing behind the tailbone at all. Your coccyx sits over air, not over a foam ring.
Will it slide around on my chair?
The bottom has a non-slip base designed to grip smooth, leather, and fabric chair surfaces. It stays where you put it. Repositioning your cushion every five minutes defeats the entire purpose — so we made sure it doesn't move.
Is it too thick? Will it raise me up too high?
Some cushions add 3–4 inches of height and change your posture, your knee position, and your reach in the car. The SitWell is designed to provide full support without dramatically raising your seated position. It sits comfortably in standard chairs and car seats without making you feel like you're perched on top of something.
Can I use it in the car?
Yes. Many customers keep one in the car full-time — especially for drives to appointments, grocery runs, family visits, and road trips. It fits standard car seats and SUV seats. If driving has become something you dread because of tailbone pressure, this is one of the most common places customers use it first.
Why does sitting hurt more than it used to?
Several things can change over time — the natural padding around the tailbone can thin, previous falls or injuries can make the area more sensitive, degenerative changes can occur in the joint, and spending more time sitting can increase sustained pressure. Clinical sources note that coccydynia has varied causes. The common thread is mechanical: something is pressing on a spot that can't handle the load anymore. The SitWell removes that contact.
Does it help if I hurt my tailbone years ago?
Many customers have old tailbone injuries — falls, childbirth, accidents — that resurface later in life. The SitWell doesn't heal old injuries, but it removes the pressure that makes them painful when you sit. If your tailbone hurts because something is pressing on it, and the cutout removes that contact, the relief can be significant regardless of what originally caused the sensitivity.
What about sciatica or back pain?
The contoured lumbar back supports your lower spine and the waterfall front edge reduces pressure behind the thighs — both of which can help with lower back tension and sciatic discomfort. Many customers report improvement in both tailbone and lower back pain. However, sciatica has many causes — if yours is severe or worsening, see your doctor.
Will it make getting up from a chair easier?
Some customers notice that standing up is less painful because the tailbone hasn't been loaded the whole time they were sitting. The cushion doesn't physically assist you in rising, but if your worst pain happens when you stand after sitting for a while, reducing the pressure during the sit can make the transition less painful.
It smells when I open it. Is that normal?
Yes. Memory foam can have a slight odor when it's first unboxed — this is standard foam off-gassing and completely normal. Let it air out for a day or two and it disappears. It's not a defect and it won't last.
Can I wash the cover?
Yes. The cover is removable and washable. For a product you use every day — at meals, in the car, at church — being able to keep it clean matters. Remove the cover, wash it, and put it back on.
What if it doesn't help?
Send it back within 90 days. Full refund. No questions asked. You've already been burned by cushions that didn't work — we're not going to make you fight for your money back if this one doesn't either.

Specifications & Instructions
Your tailbone shouldn't decide how long you get to sit. The SitWell's open coccyx cutout removes all contact with your tailbone so nothing is pressing on the spot that hurts. The contoured lumbar back supports your lower spine while the high-density foam holds its shape day after day — not just the first week.
- Open coccyx cutout — zero contact with the tailbone. Your weight is redistributed to the areas that can handle it while the tailbone sits over open air.
- Ventilated channel — airflow through the cutout keeps you cool and dry during long sits in the car, at church, or in your recliner.
- Contoured lumbar back — supports the natural curve of your lower spine so you're not slumping forward or straining to sit upright.
- Wraparound side bolsters — cradle the hips and reduce pressure on the sit bones so relieving your tailbone doesn't just move the pain somewhere else.
- High-density memory foam — holds its shape through hours of daily use. This is not the foam that goes flat after a week and puts you right back on the hard seat underneath.
- Waterfall front edge — no pressure behind the thighs, better circulation during long sits. No numbness, no tingling.
- 17" × 16" × 14.5" (44 × 40 × 37 cm) — fits standard dining chairs, recliners, gliders, car seats, and wheelchair seats.
- Removable cover — cover is removable and machine washable. Foam itself is not safe for washing.
Sit through the whole meal. Stay for the entire service. Make the drive without dreading it. Take it from room to room, chair to chair, or keep one in the car and one at home. A note on unboxing: memory foam has a slight odor when new — let it air out for a day or two and it disappears.
