Size guide
Most rooms look best with a simple mix of square and lumbar pillow covers.
Start with two 50 X 50 cm covers at the back, then layer one 45 X 45 cm or one 30 X 50 cm cover in front.
Use larger square covers behind smaller squares, then finish with a lumbar cover for a clean hotel-style layer.
For a fuller look, choose inserts that match the cover size or are 1 to 2 inches larger.
