The process is straightforward and designed to guide you through each step. In no time, you’ll be ready to place an order for your perfect rectangular cushion covers.


Accurate Measurements for the Best Fit

Next, it’s crucial to measure your cushions correctly. For back cushions, deduct the thickness of the seat cushions underneath. This will ensure that the back cushions fit snugly on top. Additionally, if your cushions are part of a corner setup, account for the thickness of both cushions meeting in the corner to ensure the best fit.


Customise Your Cushion Comfort

Once your measurements are confirmed, you can select your desired filling for the perfect level of comfort. Whether you prefer a firmer seat or a softer, more relaxed feel, you can choose the filling that best suits your needs. Alternatively, if you already have your cushion inserts, you can opt for the cover only option.


Enhance Your Cushions with Optional Extras

For a fuller appearance and added comfort, consider adding optional extras like Dacron or Stockinette. These materials add extra loft and help your cushions retain their shape over time. With these small additions, your rectangular motorhome cushion covers will look and feel even better, while extending their lifespan.


Select the Perfect Fabric for Your Style

Next, choose a fabric that matches your motorhome’s décor. From durable, weather-resistant fabrics perfect for outdoor use to soft, indoor-friendly materials, there’s a wide selection available.
