Wonderful. This topper made me think I was sleeping in a 5 star hotel. It turned my unpleasantly firm mattress into a comfortable sleep.  It fluffed up quickly when the instructions told me to shake vigorously for 5 minutes. It's quite luxurious, in my opinion.  When I watch t.v. in bed, it's comfortable. I sit up, using my Wayfair pillows, and lean against my Wayfair headboard. I love this Mattress pad. It stays fluffy....so far so good.
