How to Make a Window Seat Cushion

Any room can benefit from the pleasant addition of a window seat, which provides a comfortable place to read, unwind, or take in the scenery. However, spending money on premium window seat cushions is crucial to maximising comfort. A well-made do-it-yourself window seat cushion can offer the ideal ratio of comfort and style, whether you're building a new seat or remodelling an old one. Selecting the appropriate window seat foam and making sure it is cut to size exactly are essential to getting the most comfort possible.

In addition to improving comfort, adding a soft cushion to your window seat enhances the room's appearance. If you have the correct supplies and equipment, you can make a personalised cushion that blends well with your decor.

Different Types of Window Seat Foam Cushions

Depending on your requirements and tastes, there are several things to take into account when choosing or creating bespoke window seat foam cushions:

  • Bench-style Cushions: These are straightforward, flat cushions that are intended to cover the whole seat and offer steady support.
  • Tufted Cushions: These cushions include sewn buttons or patterns for depth, giving them a more opulent and ornamental appearance.
  • Boxed Edge Cushions: These cushions have a neat, fitted appearance thanks to their structural design and piping around the edges.
  • Pillow-top cushions: These luxurious, overstuffed cushions offer an additional layer of softness for the utmost relaxation.
  • Custom Shapes: Window seat foam can be cut to size to provide a precise fit, regardless of whether you have a bay window or a specially shaped seating area.

What Type of Foam is Best for a Window Seat Cushion?

Choosing the appropriate foam cushion for your window seat is essential for comfort and longevity. Several common varieties of foam are as follows:

  • High-Density Foam: Perfect for frequently used window seats, this foam offers firm support and holds its shape over time.
  • Memory Foam: Provides a luxurious, body-molding texture that is ideal for optimal comfort.
  • Reticulated Foam: This water-resistant, breathable material is perfect for window seats in humid environments.

Selecting and using our foam cut-to-size service guarantees that it will fit your seating area precisely and offer the appropriate amount of support.

How Thick Should a Window Seat Foam Cushion Be?

Your comfort preferences and usage will determine how thick your window seat foam cushion is. Typical choices for thickness include:

  • 2 inches – Ideal for light-duty, ornamental sitting
  • 3-4 inches – A good mix of support and comfort for frequent usage
  • 5+ inches – Perfect for high-traffic areas for optimal comfort and longevity

A three to four-inch thick foam cushion is the most popular choice for comfort and durability.

Key Materials & Tools Required for a DIY Window Seat Cushion

To create your DIY window seat cushion, you will need the following materials:

  • Window seat foam cut to size (your choice of thickness and type)
  • Fabric of your choice (durable and easy to clean)
  • Batting aka Polyfibre/Dacron wrap (for added comfort and smoothness)

You will also need tools such as a measuring tape, sharp scissors or an electric knife (for cutting foam), fabric scissors, a sewing machine, a staple gun (if attaching fabric to a wooden base), pins, and chalk for marking.

Create Your Own Window Seat Cushion: A Step-by-Step DIY Tutorial

Follow these easy steps to create a custom window seat cushion that fits perfectly in your space:

  1. Step 1: Measure your space – To find the proportions for your window seat foam and fabric, measure the window seat's length, width, and depth.
  2. Step 2: Cut the Foam – Accurately measure and cut the window seat foam to size with an electric knife or sharp scissors.
  3. Step 3: Add Batting (Polyfibre/Dacron Wrap) – For a smoother and softer finish. Cut off any excess material.
  4. Step 4: Cut the Fabric – Cut your chosen fabric with a 2-inch margin on all sides to allow for seam allowance and wrapping.
  5. Step 5: Sew the Cover – Sew the fabric pieces together, leaving space for the foam to be inserted using a Velcro or zipper.
  6. Step 6: Insert the Foam – Make sure the foam fits snugly inside the cover by carefully inserting it.
  7. Step 7: Finishing Touches – Sew or tightly seal the cover before placing the cushion onto your window seat.
