Slept on it about 10 days. Very plush, soft surface great for arthritic shoulders and hip. 

However it should have reinforced edges because it sinks down a lot when sitting on the edge. Result hard to get in and out of bed. I am looking to see if there is a mattress pad that makes it a little stiffer, realizing i may lose some of the plush factor and may have to buy larger fitted sheets.

Great mattress just too soft for us...

Someone at Alwyn have a suggestion for us
