Your back spends the day leaning forward.

-
Laptop open. Coffee still hot.
-
Deadline. Shoulders up by your ears.
-
Third call. Same chair.
-
Forty minutes behind the wheel.
-
Five minutes on the floor.Level 1, arms overhead, phone in the other room.
Uncurl won't change your job. It gives your back a few minutes bending the other way.
Made for desk days, long drives, gaming nights and anyone who carries a toddler on one hip.
Lie down. Let the curve do the stretching.
Set it on the floor, sit in front of it and lean back until your back rests on the arch. No straps, no batteries, no app.
It bends you the other way
After hours of leaning toward a screen, your back rests over a curve instead. You decide how deep it goes by how much weight you let go.
Three heights in one board
Click the arch into a different slot: 2.76, 3.55 or 4.34 inches tall. Level 1 is for your first week. Level 3 is for later.
You'll feel the nodes
96 small bumps press in as you settle. A silicone strip runs down the middle, right under your spine.
It hides under the couch
It comes apart and ships in a package 2 inches thick. Put it together, use it, slide it away.
Every part, and what it's for
Plastic and silicone. Nothing to charge, nothing to plug in.
Silicone strip
Runs along the top of the arch, under your spine. Softer than the frame around it.
96 nodes
Small rounded bumps on both sides of the strip. You feel them press in as you settle.
Frame and base rail
ABS plastic, rated for up to 220 lb. The flat rail underneath keeps the arch standing.
Height slots
Three slots on the base. Move the end of the arch to a different one to change the height.

Pick your starting height
Short answer: level 1. Everyone starts there, then moves up when it feels easy.
Where everyone starts. The gentlest curve, and the one to stay on if you're on the shorter side.
Your first session, step by step
The maker's instructions, plus one step we'd add.
Set it to level 1
Put it on a yoga mat or carpet, not on a slippery floor.
Sit in front of it
Sit on the floor with the wider end of the board behind you.
Lean back slowly
Take your weight on your elbows and lower your back onto the arch.
Arms up, breathe
Rest your arms over your head. 30 seconds is plenty the first time.
Roll off to the side
Don't sit straight up. Roll onto your side, then push up with your hands.
Stop if it hurts.
Feeling a stretch is the point. Sharp or shooting pain is not. Wait about 20 minutes after a meal before using it.
Not a medical device. If you have a back condition or a recent injury, had spine surgery or are pregnant, ask your doctor first.

Board, foam roller or just the floor?
All three can stretch your back. They ask different things of you.
| Feature | Uncurl board | Foam roller | Floor stretches |
|---|---|---|---|
| How it works | You lie still on a fixed curve | You roll your back over a cylinder | You hold each pose yourself |
| Effort while using it | Low. Lie down and breathe | Medium. You push and roll | Medium. You hold the position |
| Adjust the intensity | 3 heights | Buy a different diameter | Change the pose |
| Stays put under you | Yes, it sits on a flat base | No, it rolls | Nothing to move |
| Price | $39.99 | Varies | Free |
| Storage | Comes apart, 2 in flat | Long tube | Nothing to store |
If floor stretches already work for you, you don't need this. If you never get around to them, a board you only have to lie on is easier to keep using.
Questions before you order
Still unsure? Message us.
It's a stretching board, not a medical device, and we don't make medical claims. If you have a back condition or a recent injury, had spine surgery or are pregnant, ask your doctor before using it. Stop if anything hurts.
Level 1, for about 30 seconds. Move up a level when a full minute on the current one feels easy. Use the height picker if you've used one before.
That's the most common first reaction. Stay on level 1, keep it short and lower yourself more slowly, with your elbows taking some of your weight. A stretch is fine. If it hurts, stop.
Start with 30 seconds. Build up to a few minutes as it gets comfortable.
Some people hear a pop or two when they lie back. Some never do. Either way, don't chase it. The stretch is the point.
220 lb (100 kg). If you weigh more, please don't buy this one. We'd rather lose the sale than have it give way under you.
The maker says it can sit against a chair back or a car seat. We haven't tested that yet, so for now we sell it as a floor stretcher.
Click the end of the arch into one of the three slots on the base. A user manual comes in the box.
