What it’s like to use

This is a camping-brand design: a foam core that draws in air through a one-handed valve, so you can adjust firmness while seated. Die-cut foam is meant to reduce pressure on the spine while giving some side support.

It weighs next to nothing and rolls up small, which makes it a good fit for flights, long drives and hiking or camping seats. For a permanent office chair it is expensive compared with standard memory foam cushions, so it makes most sense for portability.

Pros

Ultralight at around 100 g and packs very small
Firmness adjustable with a one-hand valve
4.4★ rating from about 2,600 ratings
Well suited to flights, car trips and camping

Cons

Expensive at $65.24 compared with memory foam options
Inflatable design needs adjusting rather than a fixed contour
Not the cushiest option for all-day office use

Who it’s best for

Travellers and campers who want a compact, adjustable lumbar support.
