Review: It's a difficult choice to make when ordering a mattress online without being able to test it. I had a very soft mattress previously that was uncomfortable for overnight sleeping. I knew I needed something much more firm, but the idea of ordering a "hard" mattress plays a trick on your mind, especially when all the ads and features talk about being soft and like a cloud. This mattress is firm as in the weight of my body doesn't sink into it but it remains soft to the finger touch and comfortable. I'd buy it again. It comes rolled and condensed in a box that is pretty heavy so you'll need some help to maneuver it, but once you remove it from the box and the plastic bag, it unfolds on its own and it was ready to lay on it within an hour.
Review: Not too soft (which was a concern) and it soaks up all the pressure points. And, not hot or warm (another concern) seems to be just right in that area. The XL Twin fit this new frame in width, but the mattress was 2 " too long in the length. I checked the measurements. It was the frame too short... So watch the frame. .. they don't have accurate measurements. This mattress is sure to measurement.

*by S***R on 15 January 2020*

I’ve recently been suffering from continuous neck, back and hip pain and have pinpointed the source as this mattress. I went back in my Amazon orders to see when I purchased this mattress and am shocked to see that it was in September of 2018 and today’s date is January 14, 2020 so not even 2 years have passed with this mattress that supposedly has a 10 year warranty(3 year limited) I purchased my Casper mattress right after giving birth to my now 2 year old daughter. I needed a firmer mattress and was between buying a Casper or Purple brand mattress. I eventually chose Casper after seeing it on Amazons daily deals and believing they had superior customer service. Which couldn’t be further from the fact... To be honest I really didn’t care for the mattress from the get go. When we received the mattress we were dissapointes by the size/thickness.The Casper mattress it’s self is abut 3/4 as thick as what one would call a regular basic size mattress. Life at that time was chaotic with a new baby, We chose not to return it despite our unsatisfaction and make the best of the situation because we would of been responsible for shipping costs to return a king size mattress and be sleeping on the floor waiting for the refund to process. To compensate for the difference in thickness we bought a thick mattress topper and a mattress protector/pad. After that we didnt have any complaints or problems for the first year. THen slowly I started to get minor aches/pains and tossed and turned at night but I initially thought it was work or I slept wrong etc. When my pain got to the point where I couldn’t ignore it anymore. My husband and I tried the most obvious solutions like rotating the mattress, new pillows, another pillow topper, multiple massages none of these interventions helped and it became absolutely clear the pain im suffering from is a direct result of this mattress losing support. When I wake up I feel like I’ve been beaten, I’m stiff and sore with nagging aches in posterior hips (which I’ve never had pain here before) Just for reference sake. I am a very slender female and only weigh 130 pounds. I do yoga several times a week to keep my muscles from getting tight. My husband is also not a “big guy” 5’10” 160 so there is no reason for this mattress to decompensate so quickly. Casper refers to what we described as “normal softening” over time so they can get a way not honoring their warranty/guarantee. so now Im in pain, in need of a new mattress and have wasted a couple thousand dollars.. I almost never leave reviews for products but I felt that I MUST WARN anyone considering purchasing this brand!! Don’t just take my word, look them up!!, the Casper company has gotten a lot of negative publicity in the news lately. The company Itself is not making any profits and is inundated with returns. I can completely see why... My only hope is for the company to read this review and do the right thing and return or replace this mattress. If anyone has any suggestions, I’m all ears. I hope this helps someone.
