Frequently Asked Questions

Thickness recommendations:

  • Living areas: 4" or thicker for all-day comfort
  • Dining benches: 2-3" provides adequate support
  • Decorative seating: 2" minimum

Beyond rectangles and squares, we create:

  • L-shaped cushions for corner seating
  • Trapezoid cushions for angled benches
  • T-shaped cushions for built-ins
  • Curved cuts for bay windows
  • Any shape your space requires

Depth guidelines:

  • Standard comfort: 21-24 inches deep.
  • Petite users: 18-20 inches.
  • Tall users: 24+ inches may be preferred.

The factor determining the difference here is material composition. A square/rectangle seat pad is usually thinner and made from hard materials like vinyl or woven, where the main focus is to protect the seat instead of comfort. Whereas rectangle/square window seat cushions are usually thicker and crafted from soft, pliable materials such as foam that focuses on delivering comfort and shape retention.

These seat pad cushions are great for compact benches, your entryway seating, or the spots where there is less space but comfort still matters.

All our rectangle window seat cushion covers have YKK zippers, facilitating easy removal. Most of our cover fabrics can be spot cleaned or gently washed. Please refer to care labels for specific care instructions.

Absolutely. Just choose a durable fabric and high-density foam to ensure the cushion stands up to your daily wear and tear.

Yes, you can. We recommend requesting swatches so you can feel and see the fabric in your space before finalizing your order.

Very Satisfied Customer

My custom made trapezoid cushion was a perfect fit. It was delivered ahead of schedule. They called to verify cushion thickness, and requested I send a photo of the sketch with measurements to recheck. I am very pleased with its appearance and comfort. Great product, carefully constructed and great customer service. I will use again if needed. Thank you. MKHolland Shawnee OK

Awesome! So happy with cushion!

Zip Cushions was absolutely amazing to work with. Their team was incredibly thorough and took the time to double check all of my measurements to make sure everything was perfect. I really appreciated the attention to detail and care they put into the process. My new cushion turned out beautifully and fits exactly as I hoped. The quality is excellent and you can tell it was made with precision. Shipping was also very quick which made the whole experience even better. I would highly recommend Zip Cushions to anyone looking for a custom piece done right.
