WOW...  The is one divine mattress!  As someone who has Arthritis and has never been happy with store-bought mattresses, I was holding my breath until the showed up one day before the scheduled arrival...  This mattress is a complete dream: firm on the bottom part but the softest and most comfortable top layer ever!  Will order another for the trundle part of the daybed before long...  Great buy and super price!  Thanks to Wayfair for carrying such great products!
