The Pillow Guide
For Furniture
Chairs: Choose a small lumbar pillow (12” x 21”) or a small square pillow (20” x 20”).

Use a lumbar pillow on slipper and occasional chairs, and a square pillow on larger chairs like wingbacks or club chairs for comfortable support.

Loveseat or Small Sofa: two 20” x 20” pillows with two 12” x 21” lumbars in front
Standard Sofa: pick use two 22” x 22” square pillows with two 20” x 20” pillows in front
Sectional: Use the standard sofa configuration above but add 2 pillows in the corner turn
