Outstanding customer service, so helpful and responsive. Gave clear and useful guidance. The product is exactly as described and was made and dispatched quickly. My daughter has been using it with her aerial aframe for a few weeks and is really happy with it.
We purchased new outdoor seating cushions for our rattan daybed/sofa, two of which were odd shapes, we were over the moon with the good quality and the speedy service that we received. The cushions arrived quickly and they fit the frame perfectly. Would definitely highly recommend using Kosi.
