    Wow. Zip Cushions is awesome. We ordered backs from another supllier because they were big time on sale. They didnt have enough remaining to also get the bottpm cushion. I ordered a bunch of fabric swatvhed from Zii Cushions to see what would look best. Zip Cushions has the best selection of fabrics ive seen hands down. Then webirdered custom bottom cushions and they are perfect. They teached out before making them to be sure the ties and details we entered online were correct. And the cushikns got here so fast its hard to helieve they were madenjust for us. Excellent everything!
