Unbent · Warm lumbar support

Fifteen minutes. Then the evening's yours.

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.

£109Free tracked UK delivery · 30-night home trial
  • Fifteen minutes before you get up, so you're not getting off the settee from a back that's been sinking all evening.
  • Your evening back: the film, the walk, the floor with the kids.
  • Holds the curve your back loses when you lie flat, so the muscles can stop holding it.
  • Warmth and a slow rhythm at once, right in the small of your back.

I've tried everything. Why would this be different?

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.

Is it safe for my back?

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.

What if it doesn't help me?

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.

Is it worth £109?

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.

How soon will I feel it?

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.

When will it arrive?

Free tracked delivery across the UK, usually 3 to 5 working days. You'll get a tracking link by email when it's dispatched.

It's not just a bad back. It's everything you stop doing.

Real words, real backs

What people with sore backs actually say.

Overheard on UK back pain forums. They aren't our customers. Next to each one, where Unbent comes in.

I hobble for a good ten steps after getting up off the settee.

— on getting up
Where Unbent comes in

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.

I've tried everything. Nothing works.

— on remedies
Where Unbent comes in

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
Where Unbent comes in

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.

Is this you?

Fine at 9am. Tight by 6pm.

Be honest. Nobody's watching.

The reason

Why lying down doesn't switch it off.

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."

How Unbent works

What a braced back needs to let go.

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.

Why it's different

The usual fixes give you one of the three.

That's why they help for ten minutes and then it's back. Unbent gives you all three, lying down, at the same time.

Questions before you buy? A real person replies, usually the same day. Get in touch

Questions people ask.

Will it fix my back?

No, and we won't pretend it will. Unbent is a comfort device for everyday tension and stiffness. If you have ongoing or worsening pain, numbness, or pain down your leg, please see your GP or a physio.

How long does a session last?

Fifteen minutes is plenty. It switches itself off after 30. Most people use it once in the evening.

Can I give it as a present?

Yes. That's what Two Unbent is for: one for you, one for the person who keeps saying "I'm fine". Both are covered by the 30-night trial.

Does it need to be plugged in?

No. It's rechargeable, so you can use it on the sofa or in bed without a cable. Charge it over USB-C between sessions, not while you're using it.

What's in the box?

Unbent, a USB-C charging cable and a user manual in English.

How big is it, and how warm does it get?

41 × 30 × 12 cm and 850 g. Two fixed heat settings, up to 55°C on the warmer one, so start on the lower setting. The polyester cover isn't removable or washable.

How does the Halloween offer work?

From 25 October to 1 November, Two Unbent costs £169 instead of £189. The price comes off automatically at checkout. Same delivery, same 30-night trial.

Where are the reviews?

Unbent is new, and we only show reviews from real orders. They'll appear here as customers write them. The quotes further up are from UK forums, not customers. Until there are reviews, the 30-night trial is how you find out for yourself.

Fifteen minutes tonight.

Unbent won't fix a bad back. It gives the muscles that held you up all day a reason to let go, every evening, on your own sofa.
