20" x 20" Size Cushions & Covers

No products found

Our 20" x 20" cushion covers collection brings together every design we stock in this larger square size — particularly suited to bigger three and four-seater sofas where a standard 18 inch cover can look a little undersized.

A 20 inch square is a larger size that looks proportional on bigger sofas and floor cushion arrangements. In a mixed arrangement, 20 inch covers work well as the back or middle layer with smaller covers in front. Use a pad of the same size or one to two inches larger for a properly filled result.

20" x 20" Cushion Covers

A 20 inch square cushion cover is a generous size that suits larger sofas, statement arrangements, and settings where a bigger, more substantial cushion is called for. We have brought every design we stock in this size together in one collection, covering the full range of styles, colours, and fabric types available in a 20 inch square. Whether you are looking for a bold patterned cover, a luxurious velvet design, or a simple plain option to balance a more complex arrangement, you will find it here without needing to search through other sizes.

The 20 inch size works particularly well as the back or middle layer in a mixed-size sofa arrangement, with smaller covers in front for a layered, professional look. Our velvet cushion covers range has popular velvet options in this size that look particularly striking on a larger sofa. Our plain and solid cushion covers collection has neutral options that work well as a base for a more complex arrangement, and our full cushion covers range covers every other size if you need a different dimension.
