Window Seat Cushions: Comfort + Design Tips

A well-styled window seat can turn any overlooked nook into a cozy, functional retreat. Whether it’s a place to sip coffee, read, or add extra seating, the right window seat cushions are what make the space feel intentional and inviting.

A well-styled window seat combines comfort and design - layer custom cushions with soft pillows and personal accents for an inviting space.

In this guide, we’ll cover everything you need to know - from choosing the right foam to fabric selection, sizing, and designer finishing details.

Window Seat Cushions - What to Consider Before You Order

Creating the perfect window seat cushion takes more than just picking a fabric. Here are the core elements to get both comfort and design spot on.

1 - Get the Right Measurements

Always measure the width, depth, and thickness of your seat space — and measure twice. If your window seat is built-in or has curved corners, creating a template is often the safest route.

Tips:

• Standard thickness is 2”–4”

• Don’t forget to account for pillows or bolsters

• For deep seats, add extra depth for back support

2 - Choose the Best Foam Fill

Foam density affects comfort and longevity. For window seats, where sitting is upright, medium-to-firm foam works best.

Popular Cushion Fill Options:

• High-density foam – supportive and durable

• Foam with batting wrap – for a soft finish and rounded edges

• Memory foam or down-wrapped foam – for a plush, premium feel

3 - Select Durable, Stylish Fabrics

Window seats get a lot of use and sunlight. Choose fabrics that offer both beauty and durability.

Recommended Fabrics:

• Performance fabrics (fade and stain-resistant)

• Cotton-linen blends for a relaxed look

• Velvets for a luxurious finish in low-traffic areas

• Patterns or textured solids to hide wear

4 - Consider Custom Details

Small details can elevate your window seat cushion from standard to showpiece.

Custom Options Include:

• Piping or contrast welt

• Tufting or button details

• Removable covers with zippers

• Ties or Velcro to hold the cushion in place

• Custom edge styles (knife edge, boxed, etc.)

5 - Add Accent Pillows and Bolsters

Layering a few custom throw pillows or bolsters instantly makes the window seat more inviting and comfortable.

Style Tip:

Coordinate pillow fabric with your cushion or drapery for a cohesive look.
