Lumbar Pillow Sizes and Where to Use Them
Lumbar pillows come in three standard sizes. The 13x21-inch is the most versatile — it fits armchairs, accent chairs, and smaller sofas. The 16x26-inch works on full-size sofas, sectionals, and king beds. The 14x40-inch (extra-long lumbar) spans wider furniture like daybeds, benches, and king headboards. For a sofa, place one lumbar pillow at each end alongside your square throw pillows. On a bed, center a single lumbar pillow in front of your shams for a layered look.
Fill Types: Down, Poly, and Cover Only
Down-feather inserts feel softest and hold their shape with a casual, relaxed look. They compress more over time and need occasional fluffing. Poly inserts are firmer, hypoallergenic, and hold their shape longer — a better choice for pillows that get daily use. Cover-only options let you reuse inserts you already have or choose your own fill density. Most of our Loloi and Chris Loves Julia pillows offer all three options at different price points.
Materials and Construction
Our Filling Spaces pillows are handmade using traditional block printing on linen, with select styles in cotton-linen blends. Loloi and designer collaboration pillows (Amber Lewis, Chris Loves Julia, Magnolia Home by Joanna Gaines) feature woven construction in cotton, cotton-viscose, and cotton-linen blends with printed or textured patterns. Pom Pom at Home offers down alternative inserts in woven cotton casings. Ethnicraft Nomad outdoor pillows use weather-resistant woven canvas for patio and outdoor seating. Each material ages differently — linen softens over time, while woven cotton holds its original texture longer.
Frequently Asked Questions
What size lumbar pillow do I need for my sofa?
For a standard 84-inch sofa, use 16x26-inch lumbar pillows. For loveseats and smaller sofas under 72 inches, 13x21-inch works better proportionally. Place lumbar pillows at each end of the sofa, angled against the arms, layered in front of larger 22x22 or 24x24 square pillows.
What is the difference between a lumbar pillow and a regular throw pillow?
Lumbar pillows are rectangular (wider than tall), designed to support the lower back curve. Standard throw pillows are square (18x18, 20x20, 22x22). The rectangular shape of a lumbar pillow fills the gap between your lower back and the seat, providing ergonomic support that square pillows cannot. They also add visual variety when mixed with square pillows on a sofa or bed.
Should I buy a cover only or a pillow with insert?
Buy cover-only if you already have inserts at home or want to control the fill firmness yourself. Buy with an insert if this is your first lumbar pillow or you want a ready-to-use option. Down inserts cost more but give a relaxed, designer look. Poly inserts cost less and stay firm for high-traffic seating like a living room sofa.
How do I clean a lumbar pillow cover?
Remove the insert first. Most linen and cotton covers can be machine washed cold on a gentle cycle and tumble dried low. Handmade block print covers from Filling Spaces should be dry cleaned or hand washed to preserve the print. Check the care label on each pillow — washing instructions vary by brand and material. Spot clean non-removable covers with mild soap and water. Ethnicraft outdoor pillow covers can be wiped down with a damp cloth.
