Very attractive, soft, well sewn, but it would not strike me as extra thick, but medium thick. It easily fits our rather deep mattress, but it actually overhangs all four sides, making it hard to keep in place, because it has considerably less structure than the last one I got from Wayfair. I thought the cooling aspect would be good, what with the heat waves coming but we are in the middle of a weird cold snap so no way to tell:). We will fidn out this weekend as it heats up. All in all, a decent topper but not super great.
