Best Mattress I've Ever Had
I have never had to purchase a mattress. We have always had one passed down to us. So going through the shopping process was very stressful. I was ready to settle on a certain mattress from a local company when a friend told us about Casper. I purchased a Cal King mattress and 2 King pillows based on the recommendation of the friend. This was one of the best decisions I've ever made! I didn't know how important it was to have a good mattress. Word of mouth goes a long way!

Body changing mattress.
[This review was collected as part of a promotion.] My husband and I ventured across country, bought an Agency, between our home and business have moved 7 times. our backs, neck, shoulders, heck every inch of us was in pain for a good 2 years. Since our Casper arrived and our bodies adjusted we have improved sleep, improved physically which in turn means better moods for the household. We are so so thankful for our Casper. Next, we're hoping to get Casper pillows for us and our two girls.

Thrilled beyond belief
I was a little uncertain about the unboxing, it seemed like it should have been more challenging. I managed the 85 lbs box on my own (I'm 5'4"). The hardest part for me was getting the mattress out of the box. Once out, the mattress was super easy to set up. I am loving my Casper. It supports me in all the right spots. The only thing I am not adjusting to is how cool I am at night. My old mattress was like an oven. But, I know I will adjust and come summer, this mattress will be amazing! I am so happy I finally treated myself to a Casper.
