  • So far, so good!
Size: Twin XL Pattern Name: Mattress
So far, I love it! The bottom of the mattress is a little grippy and the mattress doesn’t slide on my frame. Love the quality casing that comes off for cleaning. Feels supportive. Solid quality. Good choice. 2 days: Yes, very comfortable! Very happy with this investment!

  • 2 years in- still IN LOVE
Size: Queen Pattern Name: Mattress
We got this mattress after doing some research on supportive and affordable mattresses. It has been 2 years now and I am still in love!! It has stayed supportive and in peak condition the whole time. Typically, I like a soft mattress, however they always end up sinking and not being supportive. This mattress hits that sweet spot of support and comfort. It does a great job of isolating movement, when my husband rolls over in the night I am not getting shaken awake. I would highly suggest this mattress if you were considering it and have encouraged family to also purchase! ... show more

  • Expensive, but absolutely worth it
Size: California King Pattern Name: Mattress
All of my dads side of my family (including myself) suffer from chronic back pain, we're also mostly above 6' tall (I'm 6'6 lol) and have struggled with severe pain since I was a kid. Growing up, and until now I had typical hybrid mattresses with coils and whatnot. My neck, shoulders and back would all be stiff when I woke up. Not with Casper. It's an absolute game changer if you struggle with pain or sleep in general. The top layer is extra soft for your pointy bits, but is still extremely supportive. I've never experienced this much comfort in a bed before. It costs a pretty penny, but in my opinion, it's worth every cent. *It is on the softer side. So if you prefer a stiffer mattress I'd recommend going up a level. Thank you, Casper. ... show more

  • Good mattress, FIRM
Size: Queen Pattern Name: Mattress
There are many reviews that say this mattress is soft but it is definitely firm. I prefer medium and saw people said there’s a good flexible bounce atop a firm base so I thought I’d find that happy medium here. It is comfortable for side sleeping- my shoulder sinks in enough but I roll onto my back in the night and I woke up with a stiff lower back because the firmness around my hips didn’t allow them to sink in enough. I’m a lightweight sleeper so if you’re a heavier sleeper this might not be a problem for you, but it was so stiff for me that it caused pain. I’m not really someone who feels pain from a mattress easily either. I kept the mattress, however, because it is in fact so structurally sound, and added a 2 inch memory foam topper to reduce that stiffness. ... show more

  • Casper, Great price
Size: Queen Pattern Name: Mattress
Just received this mattress today. I chose the Casper by the reviews. I didn't want a cheap mattress by a brand I've never heard of. I don't mind the price point for a name brand one. As soon as I opened it, it expanded right away. I laid down for a few. Seems pretty comfortable to me. I have a bad back. Hopefully this helps. I don't notice any bad smell as others have stated. ... show more

  • Not bad
Size: Full Pattern Name: Mattress
It’s been almost 2 months so that adjustment period is over (thank God) and I actually stay asleep throughout the night now. I initially experienced terrible back and neck pains in the first month but I’m pain-free now with virtually no tossing and turning according to my Fitbit. I find I’m most comfortable sleeping on my back, this could be due to the cold weather stiffening up the foam material causing it to be firmer than what it will be in the summer. There wasn’t a weird smell or off-gassing when first unwrapped, but I wanted to let it expand for 24 hours as this is crucial with memory foam mattresses. No sagging, no indentations, no complaints! And the Black Friday sales price was amazing. Such a steal. ... show more

  • It Does What A Mattress Is Supposed To Do!
Size: Full Pattern Name: Mattress
My wife found this mattress on Amazon during "Prime Day". We needed a new king mattress, but we didn't want to spend a ton of money, so we did some research and found this one. We read the reviews and felt that this was a good mattress. One review spoke about fiberglass in the mattress, so we dug in on that. The fiberglass is for fire retardation, and it should never be exposed. (We discovered that many mattresses contain fiberglass for this exact reason. The one reviewer who ended up with fiberglass in their washer and dryer probably shouldn't have been eating in bed. They spilled someting in bed and they took the mattress cover off to wash it. I would not suggest doing this.) When the mattress arrived, we opened it and let it "fluff up" for 24 hours. We put it on our bed; put clean sheets on it, and went to sleep. It was comfortably soft AND firm! The next morning, we had no complaints. It's what you want in a mattress. Hopefully it will last many, many years. And, from complete strangers like us, we would recommend this mattress for your good night's sleep. ... show more
