Window Seat Cushions & Covers Made to Measure

Create a comfortable, made to measure window seat with custom cushions and covers designed to fit your space properly. Our window seat cushions and covers are ideal for bay windows, alcoves, built-in seating, reading corners and fitted bench areas around the home.

A window seat should look neat, feel comfortable and make proper use of the space. Standard cushions rarely fit well, especially in bay windows or alcoves where the shape, depth and angles can vary. By ordering a made to measure window seat cushion, you can choose the size, shape, filling and cover finish that best suits your seating area.

Whether you need a complete new cushion, replacement cushion covers, a foam interior, fibre filling, feather filling or a shaped cover, this category brings together the main options for creating a well-fitted window seat.

Made to Measure Window Seat Cushions

Every window seat is slightly different. Some are simple rectangular benches, while others sit inside bay windows, angled alcoves or awkward fitted spaces. A made to measure cushion helps create a cleaner finish because it is produced around your measurements rather than forced into a standard size.

Our window seat cushion options are suitable for:

Bay window cushions
Alcove seat cushions
Built-in window seats
Reading nook cushions
Bedroom window seats
Kitchen window seating
Hallway bench seats
Fitted home seating
Replacement window seat cushion covers

For wider home seating options, customers can also browse made to measure cushions and covers for the home.

Choose the Right Window Seat Cushion Shape

This category includes a range of cushion shapes so customers can choose the option that best matches their seating area.

Popular window seat cushion shapes include:

Square and rectangle seat cushion covers
T shape seat cushion covers
L shape seat cushion covers
Equal sided taper seat cushion covers
Bolster cushion covers
Square and rectangle back cushion covers
T shape back cushion covers
Equal sided taper back cushion covers
L shape back cushion covers

A simple rectangular cushion is often suitable for straight window seats. For bay windows, angled seating or fitted alcoves, a tapered, L shape or T shape cushion may give a better fit.

The shape pages should carry the specific product SEO. This category page should carry the broader search terms around window seat cushions, window seat cushion covers and made to measure window seat cushions UK.

Window Seat Cushion Covers Made to Measure

If your existing cushion interior is still in good condition, new window seat cushion covers can refresh the whole seating area without replacing the foam or filling.

Made to measure covers are useful when:

The old covers are worn or faded
You want to change fabric colour or texture
You are updating a room scheme
The cushion size is non-standard
You need a cover for a bay window or alcove cushion
You want a neater fitted finish than ready-made covers

Customers can choose from available cover options such as fabric, zip position, piping, stitching, pattern matching and fixtures, depending on the product selected.

Foam, Fibre and Feather Window Seat Cushions

The right filling depends on how the window seat will be used.

Foam Window Seat Cushions

Foam is usually the best option for regular sitting because it gives better support and shape retention. A foam window seat cushion is ideal for reading nooks, kitchen seating, bay windows and built-in bench seating used every day.

Fibre Window Seat Cushions

Fibre gives a softer, more relaxed feel. It can work well for back cushions or softer decorative seating, but it may not keep the same structured shape as foam when used as a main seat cushion.

Feather Window Seat Cushions

Feather gives a soft, plump and traditional finish. It is best for back cushions or decorative comfort rather than firm everyday seat support. Feather cushions need regular plumping to keep their shape.

In plain English: if people are sitting on it regularly, foam usually does the heavy lifting. Fibre and feather are better where softness and appearance matter more than firm support.

Browse Fabrics for Window Seat Covers

Fabric choice makes a big difference to the final look of your window seat. A plain fabric can create a clean, simple finish, while textured or patterned fabrics can add warmth, colour and character.

Before ordering, customers can browse our upholstery fabrics to compare colours, textures and styles. This is especially useful when matching window seat cushions to curtains, blinds, sofas, headboards, carpets or existing upholstery.

For busy family areas, choose a practical upholstery fabric suited to regular use. For occasional seating or decorative window seats, you may have more freedom with softer textures and statement fabrics.

How to Measure for a Window Seat Cushion

Measure the seating area carefully before ordering. If you already have a cushion that fits well, you can measure the cushion itself. If you are fitting a new window seat, measure the space where the cushion will sit.

You will usually need:

Width
Depth
Thickness
Shape details
Any taper, cut-out or angled measurements

For bay windows and alcoves, check the measurements at more than one point. Walls and fitted spaces are not always perfectly square, especially in older homes. No great surprise there — old houses were built with character, not laser levels.

If your cushion shape is more complex, choose the closest matching product shape or contact us before ordering.

Seat Cushions and Matching Back Cushions

Many window seats use both a seat cushion and matching back cushions. Seat cushions normally need firmer support, while back cushions can be softer and more relaxed.

Useful product routes include:

Square and rectangle seat cushion covers
L shape seat cushion covers
T shape seat cushion covers
Equal sided taper seat cushion covers
Square and rectangle back cushion covers
L shape back cushion covers
T shape back cushion covers
Equal sided taper back cushion covers
Bolster cushion covers

Ordering matching seat and back cushion covers together helps keep fabric, colour and finish consistent.
