    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
