Quick answer: choose a pillow insert about 5 cm (2 in) larger than your cushion cover. For a 45 × 45 cm cover, use a 50 × 50 cm insert for a full, plump look, or a 45 × 45 cm insert for a flatter, tailored look.

| 45 × 45 cm (18 in) | 50 × 50 cm (20 in) | 45 × 45 cm |
| 50 × 50 cm (20 in) | 55 × 55 cm (22 in) | 50 × 50 cm |
| 30 × 50 cm lumbar | 35 × 55 cm | 30 × 50 cm |
Down vs polyester inserts
- Feather/down: soft, squishy, holds the classic "chop" shape, lasts longer.
- Polyester: firmer, lighter, cheaper, and suitable for allergy-sensitive homes.

FAQ
Why do my cushions look flat?
The insert is too small or the filling has compressed. Size up by 5 cm or replace the insert.
Can I wash cushion covers?
Most cotton covers can be machine washed. Remove the insert first and reshape while damp.
