My family and I needed something to help support our backs as our mattresses just weren't cutting it. I ordered several of these in varying sizes for each of our mattresses. Unfortunately, what we received was the incorrect product (for all orders). We received the Viscoelastic memory foam (white) instead of the gel memory foam (blue). The gel memory foam is a little softer and cooler than the other which is what I needed. I contacted customer service and they responded promptly and rectified the problem. They contacted the warehouse to do a quality check before shipping the new products. We received the correct products and are happier than ever! They are so soft and feel like a dream! Not only is this a quality product, but Wayfair has a quality customer service team! I'm a happy customer!
