Measure each cushion—not the whole sofa

Choose a part below. Measure all three dimensions, then compare them with the size diagram for your selected OHSIO cover.

Seat cushion

Seat cushion: L side to side, W front to back, H thickness.
  • L: Measure side to side across one seat cushion.
  • W: Measure front to back.
  • H: Measure the cushion thickness.

Back cushion

Back cushion: L side to side, W top to bottom, H thickness.
  • L: Measure side to side across one back cushion.
  • W: Measure from the top to the bottom of the back cushion.
  • H: Measure the cushion thickness—not the sofa height.

Chaise cushion

Chaise cushion: L front to back, W side to side, H thickness.
  • L: Measure the long side from front to back.
  • W: Measure side to side across the chaise cushion.
  • H: Measure the cushion thickness.

Use a soft tape measure. Measure the cushion itself without compressing it. Measure irregular shapes at their widest points. Check length, width and thickness against the matching product SKU image; do not choose a size by seating capacity alone.

For armrest covers, measure the armrest length, width and thickness separately and check the armrest SKU diagram.

Example sectional set: 4 back covers, 2 armrest covers, 1 chaise, 1 medium and 1 small seat cover. Each cover sold separately.

Example shown: 4 back covers, 2 armrest covers, 1 chaise cover, 1 medium seat cover and 1 small seat cover. Each piece is sold separately; this is not a fixed bundle. Your sofa may need different parts and quantities. Available parts, sizes and fit ranges vary by product. Check the selected product’s SKU size diagram before ordering. Watch the measurement guide.
