One of the most common questions we get is: how many pillows do I actually need for my couch, and what sizes should I use? The answer depends on the type of sofa you have, but once you understand a few simple formulas, styling your couch becomes effortless.
The goal is to create a space that feels balanced, comfortable, and intentionally styled — without overcrowding your sofa.
L-Shaped Sectional
L-shaped sectionals have the most surface area, which makes them ideal for layering pillows and creating depth.
A tried-and-true formula is:
-
Back layer: 3 22” pillows
-
Front layer: 20” pillows layered in front of each 22”
-
Finishing touch: 1 lumbar pillow or an additional 20” pillow placed in the center
This arrangement provides structure, comfort, and a relaxed, lived-in look that works beautifully for everyday lounging.

3-Seat Sofa
For a standard three-seat sofa, the key is balance — enough pillows for comfort without making the sofa feel crowded.
Recommended setup:
-
Back layer: 2 22” pillows
-
Front layer: 2 20” pillows
-
Finishing touch: 1 lumbar pillow
The lumbar can be easily moved around when you need extra support, making this setup both functional and versatile.

2-Seat Sectional with Chaise
A sectional with a chaise can be styled similarly to a sofa, with pillows that add both visual balance and everyday comfort to the chaise.
Recommended setup:
-
Back layer: 2 22” pillows
-
Front layer: 2 20” pillows
-
Chaise side: 1 lumbar pillow or an additional 20” pillow
This keeps the chaise comfortable and styled without interfering with its function.

Loveseat
Loveseats are smaller in scale, so fewer pillows work best — but varying sizes still makes a big difference.
Recommended setup:
-
Total pillows: 2–3 pillows
-
Suggested mix:
- 1 22” pillow
- 1 20” pillow
- Optional lumbar pillow
This keeps the look cozy and balanced without overwhelming the space.

Why Varying Pillow Sizes Matters
One of the most common styling mistakes is using pillows that are all the same size. When everything is identical, a sofa can feel flat and unfinished.
Mixing pillow sizes helps:
-
Create depth and visual interest
-
Provide better back and arm support
-
Achieve a relaxed, designer-style finish
That layered, curated look you see in professionally styled spaces almost always comes from varying pillow sizes.
At Apartment No.3, our pillows are designed to mix and match effortlessly, so you can follow these formulas or adjust them to fit your space. Whether you’re styling a large sectional or a cozy loveseat, the right pillow sizes make all the difference.
