Lumbar Pillow Sizes: How to Choose the Right One for Your Sofa, Bed or Chair

Lumbar Pillow Sizes: How to Choose the Right One for Your Sofa, Bed or Chair

A lumbar pillow is a long, narrow rectangle that sits in front of your square pillows, and the right size depends on the width of the piece it's finishing. At Indaba Home, our lumbar pillows come in three sizes: 14x31, 15x42 and 21x12. The longest suits a bed or bench, the middle size suits most sofas, and the smallest suits a lounge chair.

Indaba Home is a women-owned, multi-generational Canadian family business, and layering pillows well is something we think about every day. A lumbar is often the piece that makes a sofa or bed feel finished.

What a Lumbar Pillow Is (and What Makes One "Long")

A lumbar pillow is shorter than it is long, and that proportion is the whole point. Square pillows build the back row of a sofa or bed. The lumbar sits in front, breaks up all those right angles and gives the arrangement a softer finish. It's also the pillow your lower back ends up leaning on, which is where the name comes from.

A long lumbar pillow stretches that idea further. Long lumbars have become a favourite way to finish a bed or sofa. A longer pillow reads as a deliberate design choice rather than an afterthought, and it covers more of the furniture with one piece. Our 15x42 is the long one in the collection.

Lumbar Pillow Size Guide: The Three Indaba Sizes

Every piece of furniture has a different seat depth and back height, so treat this as a starting point. Hold a pillow against the back of your sofa or the headboard if you can, and trust your eye.

Choosing a Lumbar Pillow for Your Sofa

For most sofas, a 14x31 is the easiest place to start. It's long enough to look intentional against a three-seater and not so long that it swallows a loveseat. If you're shopping for a lumbar pillow for a sofa with deep seats, the extra length keeps the pillow from looking lost.

A 15x42 works best on a longer sofa, especially one with a straight, low back. Placed centred, it almost acts like a runner for the whole piece. We like it in a quiet, textural cloth such as our Pinstripe Linen in Natural or Grey, which gives you pattern without noise.

Tight on space? Use a 21x12 at one end of the sofa, tucked beside the arm. It adds a small tactile moment without crowding anyone's seat.

Lumbar Pillows for Beds, Benches and Lounge Chairs

On a bed

Place a long lumbar in front of your sleeping pillows and shams, centred. The 15x42 is the natural choice here because it spans a good share of the bed's width and gives the layers a clear front edge. A 14x31 also works on a smaller bed or when you want a lighter touch.

On a bench

Benches at the foot of a bed or under a window look best with one long pillow rather than several small ones. A 15x42 laid lengthwise across the seat tends to look calmer than a cluster of squares.

On a lounge chair

Lounge and accent chairs call for restraint. A 21x12 sits neatly in the curve of the back and supports your lower back without pushing you forward. If the chair is generous, a 14x31 can lean against the back instead.

How to Layer Lumbar Pillows With Square Pillows

Start from the back and work forward. Place your largest square pillows against the sofa back or headboard, add a smaller square or two in front, then finish with the lumbar at the centre or toward one end.

A few habits make the arrangement look collected rather than staged:

• Vary scale, so the lumbar is clearly smaller than the pillows behind it.
• Keep one colour family across the group, then bring in a single contrast through pattern or texture.
• Mix surfaces. A nubby woven lumbar looks lovely against smooth velvet, and a block print sits well beside plain linen.
• Odd numbers tend to feel more relaxed than pairs, so three or five pillows usually look easier than four.

If you're pairing a lumbar with a patterned pillow, let the lumbar be the quieter one, or the other way around. Two loud pillows compete.

Inserts, Fill and Lumbar Pillow Covers

Yes, you need an insert if you're buying a lumbar pillow cover on its own. A cover is only the outer layer, and without a good insert it will slump and wrinkle. Match the insert to the cover's size, or go slightly larger for a fuller, plumper look.

If you're buying a finished pillow, the filling is already inside, and the choice is mostly about how you want it to feel. Polyfill holds its shape well. Our long polyfilled lumbar styles, such as Daisy Play in Black and Green, are a good example. Feather down gives a softer, more sink-in drape that you can shape with your hand. Select Indaba styles are available with a premium RDS certified feather down filler made in Canada.

Fabric matters as much as fill. Our Lina Linen pillows are made from Belgian linen, handwoven in India, and the cloth softens beautifully with use. In the 14x31 size, you'll find Lina Linen in Terracotta, Chambray and Mink.

Frequently Asked Questions

What size is a lumbar pillow?

A lumbar pillow is a rectangle that's noticeably shorter than it is long, though exact measurements vary by maker. Indaba's lumbar pillows come in 14x31, 15x42 and 21x12. Pick the length by the width of your furniture.

What is a long lumbar pillow?

A long lumbar pillow is a narrow rectangle with extra length, designed to stretch across more of a sofa, bed or bench. Our 15x42 is the longest size we offer. It works especially well centred on a bed or a long sofa.

Do you need an insert for a lumbar pillow?

You need an insert if you're buying a cover on its own, since the cover has no filling. Choose an insert that matches the cover's size, or one slightly larger for a fuller look. Finished pillows come filled, so no separate insert is needed.

What size lumbar pillow is best for a sofa?

A 14x31 suits most sofas and loveseats. On a longer sofa, a 15x42 gives a more dramatic, centred finish. For a small chair or the end of a sofa, a 21x12 is the neater choice.

How many lumbar pillows should I use?

One lumbar per sofa, bed or chair is usually enough. Its job is to finish the arrangement, not to dominate it. On a very long sofa, you could use one at each end, but start with one and see how it looks.
