Excellent quality, and to me it's a plus because it comes with a white cover that is already on Gel Memory Form Mattress out of the box.  The topper started expanding immediately and within 2 hours it was at the promised 3" in height.  It only had a slight smell that dissipated very quickly (within 2 days).  I have only  slept on for 2 nights and it is so far very comfortable. For the price, I highly recommend the Lucid Comfort Collection.
