Your knees don’t hurt when you’re moving. They hurt when you finally stop — and then try to start again.
Osteoarthritis doesn’t come with a four‑week recovery plan. It comes with the rest of your life. SitnStand is the portable, inflatable lift cushion that gives back the first ten seconds of standing up — from any chair you already own.
Everyone with OA knows these three moments.
Talk to anyone in an osteoarthritis group long enough and the same three stories come back. They are not what outsiders think arthritis is. They are what it actually feels like, day after day, for years.
The gel.
Twenty minutes still on the couch and the joints lock up. You feel welded in place. The longer you sit, the worse the first step is — so you start rationing rest.
The chair you avoid.
The deep sofa at your daughter’s house. The low booth at the restaurant. The visitor chair at the doctor. You’ve mapped every seat in your life by how hard it is to get out of.
The first ten seconds.
Not the walking. The standing up. That moment of shifting weight onto the joints that hurt most — and the deep breath you take before you try.
Standing up isn't just a movement. It's a decision to keep living.
”— The SitnStand Principle
Three steps. One remote. Any chair you already sit in.
No wires. No assembly. Slip it on the chair you already sit in and let the cushion do the lifting.
Place
Drop the cushion onto your couch, recliner, or dining chair. It stays put on any flat seat.
Sit
Sit as you normally would — the deflated cushion is firm and comfortable for long stretches.
Rise
Press the remote. The cushion lifts vertically, bringing you up to standing. No pulling. No pushing off the armrests.
You don’t need a new chair. You need a way out of the ones you already have.
A power lift recliner costs $1,500 and stays in one room. SitnStand goes with you — to the kitchen, to the car, to the folding chair at the grandkid’s soccer game. It adapts to any seat in your life instead of asking your life to revolve around one seat.
The deep sofa
The one you’ve been avoiding
Kitchen & folding chairs
No arms, no leverage — until now
Restaurant booths
Stop picking restaurants by their chairs
The car seat
The hardest rise of the day, twice a day
You’re not alone in any of this.
Excerpts from SitnStand's customer testimonial library. Full video testimonials at sitnstand.com/stories.
The first few weeks after surgery I needed help every time I stood up. With the cushion I stopped calling my husband in from the next room. That is a small thing and also it is everything.
I can get up from any chair now. It has done wonders for my mental well-being, not just my body. Knowing I can stand without asking is something I forgot was a thing you could have.
My only regret is that I didn't buy one before the surgery. I spent two years looking for something like this and the thing I needed was a cushion that fits any chair.
If you're the one they're asking for help.
The people buying SitnStand often aren't the people using it. A spouse, a daughter, a caregiver sees what recovery actually looks like — the reach for the arm rest, the second try to get up, the apology afterward.
Arthritis is not something you fix for your parent. But the chair is. SitnStand is the gift that returns one small piece of their independence every time they stand up.
What SitnStand is not for.
We’ve read enough arthritis groups to know that trust is earned by what a brand admits, not what it claims. Before you buy, here is what SitnStand does not do:
- It doesn’t treat your arthritis. It will not reduce joint inflammation, rebuild cartilage, or replace what your doctor prescribes. That’s not its job.
- It doesn’t replace PT. If movement and strength work are helping you, keep doing them. SitnStand removes the rise from the equation — it doesn’t replace the work.
- It doesn’t help with stairs. SitnStand is for chairs. If stairs are your main concern, a stair lift is the right category.
What SitnStand does is simple and one thing: it takes the pain and the effort out of standing up from a seat. If that’s the moment that’s stealing your day, this is built for you.
The questions we hear most from people living with OA.
Yes — because SitnStand isn’t trying to fix the joint. It removes the load on the joint during the rise. The moment that hurts most for people with advanced OA is the weight transfer from seated to standing, and that’s exactly what the cushion takes over for you.
Yes. SitnStand was built for daily use over years, not weeks. Many customers use it every day for the rest of their chairs’ lives. There is no wear‑out schedule, no prescription required, and no reason you have to give it up as your OA progresses.
Most pre‑surgery patients tell us the opposite: they wish they’d had one before the wait got long. The cushion helps in the months leading up to surgery, through recovery, and after — especially for the other joint that isn’t being operated on yet. It does not replace surgery. It just keeps the chair from stealing the years before it.
Fair question. SitnStand is designed to assist the rise, not replace the strength work that keeps you mobile. It doesn’t lift you like an elevator — it lifts you up so your legs still do the walking. Most users report doing more activity, not less, because the cost of every rise goes down. Keep up your PT and your walking.
Yes. The advantage of lifting you up from the seat is that it doesn’t require you to push off with your knees, pull up with your arms, or hinge from your lower back. Whichever joint is your worst joint, SitnStand takes the load off it during the rise.
60-day returns. If SitnStand isn’t the right tool for your body, send it back — full refund. It even comes with Free Returns.
