Wow. These people understand everything about making a slipcover. Not only does my new slipcover fit properly, it fits PRECISELY with no velcro or tabs to tie and no extra fabric to tuck in. The striped fabric I ordered has a big repeat (6") but in spite of this, the stripes match from back to cushions to skirt. And if I flip the cushions, the stripes still match!!! The way it works is this: you take a photo of your piece and provide a dimension or two. They tell you if they can make it and provide a base price and a measuring template. You fill in the dimensions and your customer service person walks you through the process, asking for additional photos and cross checking the dimensions. 2 of my dimensions did not add up, and through their questions, I discovered my sofa was not square, but slightly trapezoidal. And still my slipcover fits perfectly! The area under the seat is made from a non-slip material and right away the cushions on my loose cushion sofa stopped sliding down. This was a huge improvement over the original design. Also the piping is actually a soft, thickly braided cording and it feels nice to sit on and should be more durable than the fabric covered plastic piping my sofa had originally. The company encourages you to order fabric samples and their cost is refunded when you order. Fabrics are thoroughly explained--durability, weight and cleaning information is provided. Once dimensions are finalized and you have chosen your fabric, your order is worked on. I had my slipcover very quickly, I think it took less than 2 weeks for it to be fabricated and 3 days in shipment. And did I mention that it fit perfectly?
