Every hour sitting down costs you something.
It starts as an ache. By the afternoon you're shifting every few minutes, leaning on one hip, counting down until you can stand. Then standing up hurts too. Long drives, family dinners, a movie — you've started planning your day around how long you can sit.

Why this works when nothing else did
Foam flattens. Gel overheats. Air does neither — here's how they really compare.

THE END OF FLAT, PAINFUL CUSHIONS
Don't settle for foam that flattens — RESTTR adapts to how you sit and re-inflates in seconds, so it never needs replacing.
Breathable & Non-Slip
Airflow between the cells keeps you cool through long sittings, and the gripped underside stays put on any chair.
Adjustable Firmness
Inflate to your exact comfort in seconds — softer for long desk days, firmer when you want more support.
Folds Flat, Travels Anywhere
Just 300g and folds into your palm, so the same relief comes with you to the office, the car, or the flight.
Relief for every kind of sitting pain
01 / 6
Tailbone Pain
When you sit, almost all your weight lands on your tailbone. RESTTR's air cells spread that load across the whole seat, so nothing digs in — and no more stabbing pain when you stand up.
02 / 6
Sciatica
Hard seats compress the nerve running down your leg. The air lifts that pressure off the nerve path, so the shooting, burning pain eases — even on long sits.
03 / 6
Lower Back
Your lumbar aches because your pelvis tilts to escape tailbone pressure. Take the pressure off underneath and your pelvis sits neutral, so your lower back stops straining.
04 / 6
Hip & SI Joint
Sitting lopsided to dodge pain throws your hips off balance. Even support settles them level, so you stop shifting cheek to cheek — less ache.
05 / 6
Leg Numbness
Numbness comes from a hard edge cutting off circulation. The air cells cradle instead of press, keeping blood flowing so your legs don't go numb after hours.
06 / 6
Sensitive Sitting
For a bruised tailbone or postpartum recovery, direct pressure is agony. The air suspends you instead of pressing back, so you can finally sit without bracing.
Set up in seconds. Sit better all day.
Step 1. Open the valve
Flip open the cap to get started — no pump, no tools needed.
Step 2. Press to inflate
Press the built-in pump 30–40 times until it reaches your firmness — firmer for hard chairs, softer for long sits.
Step 3. Release to adjust
Too firm? Tap the valve to let a little air out and dial it in.
Step 4. Fold it and go
Deflate, roll it up, and slip it in the travel bag. Comfort anywhere.

FAQ
Foam compresses under your weight and never recovers — that's why it felt fine for a week, then flattened and the pain came back. RESTTR uses 36 interconnected air cells that redistribute your weight instead of collapsing under it. Air can't be crushed the way foam can, so it works at hour ten exactly like it did in minute one.
Even a $1,000 chair has a flat seat pan that drops your full weight onto your tailbone and sit bones. A great chair supports your back — it does nothing for the two points carrying you when you sit. RESTTR sits on top and takes the pressure off exactly where it builds.
That's the foam and gel problem — they hold heat against you. RESTTR is the opposite: air flows between every cell, venting heat continuously so you stay cool even through a full day of sitting.
No. RESTTR is just 4.5cm thick — it lifts you barely more than an inch. Almost everyone uses it with no change to their desk or chair. You'll feel the support, not the height.
No. RESTTR isn't a thin air pillow — it's made of medical-grade TPU built to hold your full body weight, sit after sit, for years. And because the cells are interconnected, your weight spreads across all of them instead of straining any single one.
No. The underside is a textured non-slip base that grips office chairs, car seats, wheelchairs and couches. Set it once and it stays — no sliding, no readjusting through the day.
Then you pay nothing. Try RESTTR for 100 days — if it doesn't change how your days feel, email us for a full refund, no restocking fee and no questions asked. The only way to lose is to keep sitting in pain.
