(This review was collected as part of a promotion.) My new Wave Hybrid Mattress was so easy to set up, and it is a dream (literally) to sleep on every night.  I am so happy that I made the decision to purchase my Casper mattress and foundation which are made of high quality materials, and look beautiful in my bedroom.  My lower back pain is gone, and I feel energized and ready for every new day that comes my way after a blissful night's sleep.  Thank you Casper!
