Seating support: mats, footrests, lumbar and cushions

These are where a seating decision gets finished. Each one changes a number you already set, so buy them knowing which.

An anti-fatigue mat, a footrest, a lumbar cushion and a seat cushion around a desk

Four products, and each one changes a measurement you have already set. That is the thread running through this whole section and the thing to understand before buying any of them.

What each add-on changes, and what it therefore requires you to re-check.
Product	What it changes	What to re-check
[Footrest](/support/footrests)	Raises the floor under your feet by 3-7 in	Nothing. It is the one that fixes rather than disturbs
[Anti-fatigue mat](/support/anti-fatigue-mats)	Lowers your effective desk height by 0.75-2.7 in	Your standing desk height
[Seat cushion](/support/seat-cushions)	Raises your seat height by 1.5-4.7 in	Whether your feet still reach the floor
[Lumbar cushion](/support/lumbar-support)	Pushes you forward on the seat by its apex thickness	Whether the seat is now effectively too shallow

The footrest is the one to buy first

Of everything on this site, an adjustable footrest is the highest-leverage cheap purchase, and the reason is structural rather than a matter of taste.

A standard desk is 29 to 30 inches, set for roughly a 5 ft 10 in user. If you are shorter and your desk is fixed, you are choosing between correct elbow height and feet on the floor. Most people resolve it by lowering the chair, which fixes the visible problem and creates an invisible one: raised shoulders and a reach up to the keyboard held all day.

A footrest removes the choice, and it does three things at once. It restores the knee angle OSHA describes. It takes load off the front edge of the seat. And it stops your pelvis rotating backwards - which is what flattens the lumbar curve your chair's support is trying to hold. So a footrest acts upstream of your lumbar support, and fixing your feet sometimes resolves a back complaint that a lumbar cushion did not. The one-minute test that decides whether you need one.

The seat-cushion trap

Worth its own paragraph because it catches people. A seat cushion adds its full thickness to your seat height. Published thicknesses across this site run from 1.5 inches to 4.7.

If your seat height was already correct, a 4.7-inch cushion has just put your feet off the floor - and the fix is then a footrest, to correct what the cushion broke. If your chair was too low for you, the thickness is a feature rather than a side effect.

Either way: work out your correct seat height first, then choose the thickness deliberately. Under 2 inches barely moves you; over 4 inches is a decision.

What decides price here

Adjustment on footrests, warranty on mats, and almost nothing on cushions.

A footrest that adjusts continuously costs a little more than a fixed wedge and is worth considerably more, because a wedge either matches your gap or sits in a cupboard. On mats, the jump from flat to contoured roughly doubles the price and buys a mechanism rather than more foam - and the one mat with a published warranty carries seven years, which is the longest term of any product on this site.

On cushions, price tracks size and not much else. Not one cushion in this category publishes foam density, which is the figure that predicts how long it keeps its shape. Every listing says "high-density memory foam", which is a phrase rather than a specification. We score that gap rather than estimating around it.

The mistake buyers make

Buying the add-on instead of fixing the cause. A lumbar cushion cannot help if your seat is too deep - you are sitting forward off the backrest and the cushion is not touching you. A seat cushion cannot fix a chair that is too high. A mat cannot make four unbroken hours of standing a good idea.

The honest order is: get the seat height and depth right, then add. These products are excellent at the problems they address and useless at the ones they do not.
