great Customer Service

Five stars is not enough. My order for my window seat cushion went perfectly, even after I made a change! Quality, price, choice, timeliness, and great Customer Service. Thank you!

Super comfortable to sit on

Excellent quality product! I contacted them through chat to ensure the cushion measurements and materials would fit my need. Cushion was for my indoor window seat. My dog gets up there often, so they recommended outdoor fabric for durability. The fabric is really nice, not like plastic at all, more like a real material. Super comfortable to sit on and having a zipper allows my to remove and wash the cover. Super happy with my purchase!

perfect fit

Wanted some customer sized trapezoid cushions for my trailer and got them from ZIPCushions. Excellent product, fair pricing, great fabric options and ultimate comfort

No regret

I was looking for a trapezoid cushion for my window bay area. I am happy that ZIPCushions designed it strictly as per my measurements. The cushion is super comfy and makes our seating pleasurable. I will buy another one for my RV camper van soon.

Great customization options

I had been looking around for a replacement cushion for my RV. You guys let me customize my whole cushion which was great and I have received the cushion as is.
