I just got them yesterday and I had the best night's sleep!  Cortney L.Verified 5/21/2026 My favorite pillow! This one pillow solved all of my problems and it can last a long time thanks to coming with fill. Item type: Standard  Melady R.Verified 4/10/2026 they are amazing super soft great for my neck perfect high Item type: Standard Tina P.Verified 9/21/2026 like pillow Item type: King Gina G.Verified 8/23/2026 Such fabulous quality and comfort beyond measure! Item type: King John F.Verified 8/18/2026 At first it seemed a little hard to get used to had to take quite a bit of stuffing out of the pillow, but when I had it adjusted to my desired firm it’s absolutely wonderful to sleep on. I’m now only using one pillow instead of two for the first time ever. Item type: Standard Diane F.Verified 8/14/2026 Love the pillow the softness, the comfy is really good and thank you for the relaxing sleep on the neck part it helps a lot!!! Item type: Standard Joel F.Verified 8/13/2026 Nice pillows 😎 Item type: Standard Victoria M.Verified 8/3/2026 I am in love with these pillows. Expensive? Yes. Worth it? Also yes. I've been struggling for years to find a replacement for my favorite pillows. I like my pillows firm and bordering on being more of a boulder than a pillow. These showed up already pretty firm so I tried them without adding any extra stuffing first. I ended up adding a little bit to each one and now they are perfect. I have no complaints about them being too hot either. I can not sleep unless I am on the verge of hypothermia an... Item type: King Kristy V.Verified 7/24/2026 Insanely comfortable and adjustable. Best pillow!! Item type: Standard Carl F.Verified 7/15/2026 These pillows are way too big. They have way too much foam inside of them and cause severe neck problems when sleeping with them. Item type: Standard Sandra E.Verified 7/5/2026 OK, I think it’s ridiculous to include that little bag of extra fluff because it’s very hard to add to the pillow. You just have blue fluff falling all over the place and I don’t think it made it any bigger. It was an OK sleep Item type: King Christie G.Verified 7/3/2026 I love love love this pillow! I took some stuffing out to my preferred squishy and it is perfect. I am a very light sleeper and this pillow has really helped staying asleep. It is super comfortable. I bought this with the cooling pillowcase and IMO is the dream combo :) The search for the perfect pillow is over FINALLY! Item type: King Adriana J.Verified 6/28/2026 A bit too high, had to adjust it..now great! Item type: King Celines M.Verified 6/27/2026 . Item type: King Jessica K.Verified 6/26/2026 I like the fact I can add or remove. It's a nice solid pillow. Item type: King Alexi H.Verified 6/23/2026 Would be better in the standard size Item type: King Jason W.Verified 6/22/2026 Pillow is super comfortable. Paired with the cooling pillow case makes for a great sleep. Item type: King Jorge C.Verified 6/6/2026 Pillows are super comfortable Item type: Standard Kelly H.Verified 6/4/2026 Not at all as good as any of the other pillows but not bad Item type: Standard Show more reviews THIS IS AN ADVERTISEMENT AND NOT AN ACTUAL NEWS ARTICLE, BLOG, OR CONSUMER PROTECTION UPDATE THE STORY DEPICTED ON THIS SITE AND THE PERSON DEPICTED IN THE STORY ARE NOT ACTUAL NEWS.
