Measure the seat length (left to right) and seat depth (front to back) of your window ledge in centimetres using a rigid tape, following the exact surface where the cushion will sit.

For straight bay windows, one set of measurements is enough. For angled or multi-panel bays, measure each section separately to capture the full shape. Always measure twice for accuracy, especially if your walls are slightly uneven.

Simply adjust the slider based on your seat length and seat depth, and the price will automatically update according to your selected size.

The larger the cushion, the more materials and craftsmanship required, which is reflected in the price. Once you’ve set your measurements, the displayed price is your final cost—no hidden fees.

All our custom bay window seat cushions are made-to-order, based on the exact measurements you provide. Because of this, it’s very important to ensure your measurements are accurate before placing an order.

We highly recommend double-checking your seat length and seat depth, as we produce each made-to-measure cushion specifically to those dimensions.

Please note that since each cushion is custom-made, we’re unable to offer returns or refunds for incorrect measurements.

Each of our custom bay window seat cushions is made to order, so we take a little time to ensure everything is crafted perfectly. Production typically takes 2-4 weeks, depending on the design and size of your cushion.

Once ready, delivery usually takes 5–7 days, depending on your location.
