Frequently Asked Questions

To create your perfect trapezoid cushion, you'll need to provide us with three key measurements. Our system will automatically calculate the angled sides for you, ensuring a precise fit every time.

Required Measurements

Bottom Width: Measure the full width of the front edge of your seating area (the wider edge that faces forward). This measurement can range from 3 to 130 inches and is available in precise half-inch increments to ensure an exact fit.
Top Width: Measure the full width of the back edge of your seating area (the narrower edge). Like the bottom width, this measurement ranges from 3 to 130 inches with half-inch precision available.
Length: Measure the straight-line distance from the front edge directly back to the rear edge. Take this measurement perpendicular to both parallel edges, not along the angled sides. Available from 3 to 130 inches in half-inch increments.
Thickness Select your desired cushion thickness from our available range, from 2 to 12 inches. Consider your comfort preferences and the intended use of the cushion when making your selection.

Automatic Calculations

Once you provide these three dimensions, our system automatically calculates the angled side measurements to ensure your trapezoid cushion fits perfectly. This eliminates guesswork and guarantees precision in the final product.

For irregular trapezoids or furniture with non-standard shapes, ZIPCushions offers several solutions to ensure a perfect fit. You can create a template using tracing paper or chart paper large enough to cover the cushion area, carefully tracing along the edges and labeling each side with corresponding measurements. For more complex shapes, you can upload a template, image, or detailed diagram along with your order.

Our customer support team is available to assist you through the measurement process, and for uniquely shaped furniture or complex configurations, our team can guide you through the measuring process and help determine the best cushion style for your specific needs. This personalized approach ensures that even the most challenging trapezoid shapes receive accurate, custom-fitted cushions.

For outdoor seating applications, reticulated foam, also known as Dry Fast Foam, stands out as an excellent option. This specialized foam features an open-cell structure that allows moisture to drain rapidly, significantly quicker than conventional cushion foams. Additionally, it comes pre-treated with antimicrobial compounds that actively resist bacteria, mildew, and fungal development, making it ideal for exposure to humidity and outdoor elements.

Yes, Sunbrella is a good choice for your trapezoid seat cushions, as it is a gold standard fabric that is made to last outdoors. It is fade, UV, and weather-resistant, withstands harsh elements to save your investment for years.

Cushions fit perfectly, well-made, fast shipping!

Exactly the size I requested — the custom dimensions were spot on and it fits perfectly. The quality is excellent: firm, well-shaped, and the material feels durable and well-made. Everything matched my order exactly. Very satisfied with this purchase

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.

Perfect fit and fabric. Exactly what I was looking for.

Great cushion for my bench seat. Just as advertised.

Absolutely perfect 😁

Great!

We got the Agora fabrics for our indoor bench cushions. The delivery was swift and the customer support was on point. They reached out to me about a questionable choice I made and I'm really glad they did. I appreciate the care they took into this order. I don't have anything bad to say about my order, but I wish I knew that for very snug fits, it'd be a good idea to order a smaller cushion than you think (probably an inch or two smaller if I were to do this again). The cover adds a fair bit to the dimensions of the cushion. I ordered the exact size of my bench, and it ends up looking too tight in my case. Not the business's fault, just that I didn't know better.

Breakfast Bench Cushions

I ordered these cushions last week and was told it would be a 3-4 week wait. What a surprise when they came today, about 8-9 days after I ordered them. They look amazing and look very professionally stitched. Thank you Zip Cushions, I never knew it would be this easy to order these on line. Would definitely recommend!

The cushion is pretty and very well made.

Cushions for Banquette

My cushions arrived in just under 3-weeks and fit my custom benches perfectly. Oscar and Isaac provised excellent customer service. They were patient and very accommodating as I had to adjust the dimensions a few times. I'm happy I chose Zip Cushions!
