Question 1

How thick should a back cushion be?

Accepted Answer

Most lumbar cushions measure roughly three to five inches at the deepest point. Thicker foam pushes you further forward, which suits deep sofas, while a slimmer profile works better in an upright dining or desk chair.

Question 2

Where on my back should the cushion sit?

Accepted Answer

Aim the thickest part at the inward curve just above your belt line. If it lands between your shoulder blades it will arch you forward, so check the listed height against the distance from your seat to your waist.

Question 3

Is memory foam or fiber fill better?

Accepted Answer

Memory foam contours and springs back, so it keeps support through a full workday. Fiber fill feels plusher and cheaper but compresses faster, making it a reasonable choice for occasional evening use on a couch.

Question 4

Will a back cushion stay put on a leather sofa?

Accepted Answer

Look for a non-slip backing or an elastic strap in the product photos. Smooth leather offers little friction, so a cushion with only a plain fabric back tends to creep down as you shift position.

Question 5

Can the cover be washed?

Accepted Answer

Many covers unzip and go in the machine on a cold, gentle cycle. Read the care note in the listing first, because the foam core itself should be spot cleaned and air dried instead of soaked.
