Tailbone Cushion or Lumbar Cushion: What Is the Difference?

By Олег МельничукPublished: 06/10/20262 min read

In short: a tailbone cushion lies on the seat and reduces pressure on the tailbone and sit bones (often with a cut-out). A lumbar cushion is a roll between your back and the backrest that supports the natural curve of the lower back. They are different items for different zones and can be combined. The choice depends on where exactly you feel discomfort.

Seat cushion (tailbone)

What it does. Spreads pressure over the buttocks and thighs and may have a tailbone cut-out so the tailbone does not touch the seat.

Who it may suit. People who feel pressure or discomfort at the tailbone when sitting, and those with a hard seat. The NHS recommends a specially designed cushion in its self-care for tailbone pain. NHS. More: tailbone pain from sitting work.

What to look at. Size, thickness, the cut-out, a non-slip base, see orthopaedic chair cushion.

Lumbar cushion (lower-back roll)

What it does. Supports the natural curve of the lower back (lordosis) while you sit and reduces the tendency to slouch.

Who it may suit. People who feel lower-back tiredness or discomfort by the end of the day, where the chair back does not support the lumbar area.

What to look at. Placement height (at the lower back), shape and firmness, and the fixing method (straps) so it does not shift.

Do you need both

Not always. If discomfort is only at the tailbone, a seat cushion may be enough; if only in the lower back, a roll; if in both zones, you can try both. But first check chair settings and posture, see typical posture mistakes, monitor height and posture.
