Lumbar support buying guide: fit, depth and materials

A lumbar support only helps if it fits your chair and your back. This guide covers the order that works: adjust the chair first, then choose a support with the right height, depth and material.

Adjust the chair first

• Feet flat, knees near hip height, small gap behind the knees.
• Screen about arm's length away, top near eye level.
• Elbows near a right angle, shoulders relaxed.

Then choose the support

Consideration	What to check
Height	Adjustable or fixed; sits in the lower-back curve above the hips
Thickness	Support without pushing the pelvis forward
Material	Memory foam (steady) vs gel/ventilated (cooler)
Cover	Removable and washable
Straps	Keeps it in place on your chair

Movement matters most

No cushion replaces changing position. Stand and move regularly; support works best alongside activity.

When to seek advice

Ongoing back pain, or pain with numbness or weakness, needs medical assessment. A cushion is a comfort aid, not a treatment.
