I hobble for a good ten steps after getting up off the settee.
— on getting up
Fifteen minutes on it before you get up. The curve is held and warmed, so you're not getting up from a back that's been sinking all evening.

For the back that's fine at 9am and tight by 6pm. Lie on it on the settee: it holds the curve, warms it and moves it gently, and switches itself off after 30 minutes.
30-night home trial. Use it every evening for a month. Not for you? Send it back and get your money back.
Most things give you one of three: warmth (a hot water bottle), support (a rolled-up towel) or movement (a massage gun). Unbent gives you all three at once, lying down, which is when a back that's been held all day gets the chance to let go.
It's gentle: a curved support, steady warmth and soft vibration, for fifteen minutes. It switches itself off after 30. It's a comfort device, not a medical device.
Please don't use it if you're pregnant, have a pacemaker or other implanted device, have had recent back surgery, or have a diagnosed spinal condition, unless your doctor has said it's fine. Don't use the heat on numb skin, and don't fall asleep with it on. If you have ongoing or worsening pain, numbness, or pain down your leg, see your GP or a physio.
Then send it back. You have 30 nights to try it at home, and if it isn't for you, you get your money back. You pay the return postage to our returns address in Spain. This is on top of your legal right to cancel within 14 days.
Used every evening for a year, it's under 30p a day. You pay once: no subscription, no appointments, no travelling. Seeing a physio? Keep going. Unbent is for the other six evenings.
You'll feel the warmth and the curve being held from the first session. Whether it earns its place in your evenings, you've got 30 nights to find out.

I've tried everything. Nothing works.
— on remedies
Most fixes give you one thing: heat, or support, or movement. Unbent gives you all three at once. And you've got 30 nights to decide.
You'd be forgiven for thinking I was 100 if you watched me get out of bed.
— on mornings
An evening routine instead of a last resort: same spot, same fifteen minutes, every night, before the stiffness has had all night to set in.
Tap the ones that sound like you.
Be honest. Nobody's watching.
The muscles that keep you upright don't have an off button. After a day of holding, they stay on guard.
Lie flat on a sofa or a soft mattress and your lower back sinks. The curve it's meant to have disappears, so those muscles keep doing the job they've done since the morning. That's the dull, tight feeling that's still there at bedtime, and the "two goes" it takes to get up off the sofa.
"It feels like a steel rod across my lower back."
Three things, at the same time, while you're lying down. One on its own helps a little. All three together is when it lets go. Switch them on.
Switch each one on and watch what happens.
That's why they help for ten minutes and then it's back. Unbent gives you all three, lying down, at the same time.
