    • Comfort first!!!
Size: King Style: 3 Inch
Love the addition. It helps balance everything out as expected. Thank you Casper. However, I rather have the entire king size casper mattress.

    • Comfort
Size: Queen Style: 3 Inch
It was perfect! Not to firm not to soft and my dog loves it too! For having back issues it's done wonders compared to a regular memory foam mattress

    • Better than most memory foam mattress pads
Size: King Style: 2 Inch
It’s super soft and just what we needed to extend the life of our old Casper mattress. No smell. The unfortunate part is you get to zip it into its case yourself. It’s frustrating, it’s awkward, I’m still not sure if I have it on right. Also this sucker moves! It’s hanging 3 inches or so off the bottom of the bed and has shifted two inches over to my husband’s side as well. You can’t just grab it and shift it back either, you have to strip the bed to move it back and a day or two she’s shifted again. It’s fine, it does offend my perfectionism sometimes, but I just close my eyes and make the bed without looking. Also, my husband generally gets too hot sleeping and this mattress pad does not make him too hot so that is a big plus. Plenty of thickness to make a difference and we’ve been sleeping on it for months. It’s definitely better than the off brand memory foam pads I’ve purchased in the past. ... show more

    • This mattress is not memory foam
Size: Queen Style: 3 Inch
Memory foam is heavy and dense. This is made to feel like memory foam but I could tell by the weight as soon as I picked it up that it is not memory foam. It is ok comfortable but not worth the memory foam price tag it has.

    • Very Comfy
Size: King Style: 3 Inch
This topper is awesome. I didn’t want one that was cooling so this is perfect for me, but I also don’t find that it makes me hot, which is nice. It honestly feels like my bed is not only taller but wider since putting it on. I just love it. The only downside was how hard it was to get it to fit inside the removable cover. That will be a disincentive to washing the cover, tbh. ... show more
