Office chairs are flat, but your lower spine curves inward — so the moment you sit, your back has nothing behind it and slowly collapses. The ZeroSlouch Lumbar Cushion fills that gap with contoured memory foam, holding your spine in its natural curve so there's nowhere left to slouch to. Breathable cover, adjustable strap that won't slide, and it moves between your desk chair, car, and gaming setup.

  • Fills the gap your chair leaves
  • Nowhere left to slouch to
  • A strap that won't slide
  • Breathable through long sittings

How to use it

Set it once and the chair does the rest.

  • Set the height

    Sit back fully, then slide the cushion so its fullest part sits in the small of your back, just above your belt line. That is the gap the chair leaves open.

  • Strap it down

    Run the strap around the backrest and pull it snug so the cushion cannot creep downwards as you move. Loose enough to shift a little, tight enough to stay put.

  • Build up slowly

    An hour or two a day to begin with. Sitting properly supported uses muscles that have been off duty for a while, so give them a week to catch up before you use it all day.

My office chair is finally usable

Nine hour days in a cheap chair had my lower back aching by 2pm. Two weeks with this and that has basically stopped.

Best thing I bought for my car

Long drives were the worst part of my job. Straps onto the seat and stays exactly where I put it.

Does not flatten

I had a foam one before that was pancaked within a month. This one still has its shape after eight weeks.

Takes a couple of days

Felt strange at first because it pushes you more upright than you are used to. Fine by day three.

Gaming chair upgrade

The built-in pillow on my chair was useless. Swapped it for this and long sessions stopped wrecking my back.

Cover comes off to wash

Small thing but it matters when it lives on a chair you sit in every day.

Wish the strap was longer

Fits my desk chair fine but was a stretch on a wide armchair. Works, just barely.

Pregnancy sitting saver

Third trimester and sitting at a desk was miserable. This made the last two months bearable.

Bought one for each room

Office, car, and the sofa. Cheaper as a bundle and I stopped carrying one around.

Firmer than I expected

Not a soft pillow, it is proper support. That is the point, but worth knowing before you order.

Colour is nice

Got the grey and it looks like it belongs on the chair rather than a medical device.

Recommended by my physio

Showed it to her and she said the shape is right. My back agrees.

FAQs

Does it actually work?

It works by filling the gap between a flat chair back and the natural inward curve of your lower spine. Without that support your back slowly collapses into a C shape over the day, which is where the ache comes from.

Give it a week or two. If your back is no better, send it back within 30 days and we'll refund you.

Will it fit my chair?

It fits most office chairs, car seats and gaming chairs. The adjustable strap goes around the backrest and holds it in place so it does not slide down when you stand up.

It is a tighter fit on very wide armchairs and some sofas.

Where should I position it?

At the small of your back — roughly level with your belt line, in the inward curve above your hips. Too high and it pushes your shoulders forward instead of supporting your spine.

Is it too firm?

It is supportive rather than soft, which is deliberate. A cushion that squashes flat is not doing anything. Most people find it takes two or three days to feel normal.

Can I wash it?

The cover unzips and can be machine washed cold, then air dried. Do not put the foam insert in the washing machine.

Which colour should I pick?

They are identical apart from the cover. Pink, brown, blue, grey and black — grey and black are the ones that disappear against most office chairs.
