WHAT A MISTAKE THIS WAS! EXTREMELY SOFT, OFFERING NO SUPPORT AT ALL!
Size: Camping(Pack of 1), Color: Original White, Size: Camping(Pack of 1), Color: Original White
INITIAL Impression: WHAT A MISTAKE THIS WAS! The foam is taking forever to expand, it is a gross color, it is way too soft where it has started to expand. The warranty says it ONLY applies to the original purchaser, which means you cannot give this to anyone as a gift, it would instantly lose its warranty. DO NOT USE ANY EXTERNAL HEAT SOURCE (some memory foam actually suggests putting it in a slightly warm dryer, but to do that would void the warranty.) I got this because I have severe back pain, but it doesn't look like it will ever be firm enough to offer support. It says it will take 24-48 hours to fully expand! I bought it because I need relief NOW, not in 2 days! It has a very limited warranty of only 3 years. The memory foam travel size pillows I bought on Amazon, made by MALOUF, in 2017 came with a 5 year warranty and are still useful, but do need replacing, 9 years later! Unfortunately those pillows are no longer available on Amazon. I chose this small Vaverto memory foam pillow "for camping", because it was available with next morning delivery with some other purchases I made yesterday. (Hoping to be able to use it TODAY.) And because most of the reviews were positive. It says on the crumpled paper warranty and directions, that ONE side of the pillow is for cooling, but WHICH SIDE? They don't tell you. The order "Shipped at 12:31 AM" the box was cold when it was "Delivered at 9:41 AM". The outdoor temperature had climbed to 51 degrees by then from a low last night of 47 degrees. My room is heated to a comfortable 78 degrees. But we still have a long way to go before this hunk of greenish blue, extremely squishy (I can pinch it at the most expanded area and my fingers nearly touch each other with maybe ¼” of foam separating them. NOT an encouraging sign. There are bits of foam starting to come out of the "punched holes" which appear to be slightly smaller on one side than the other, but WHICH is supposed to be the "cooling side that dissipates heat? Probably the larger holes, but they also weaken the firmness. On closer examination of the crumpled paper that came with it, it says '"TWO-SIDED COVER FOR VERSALITY" Then in a tiny diagram next to that, it says "COOLING SIDE DISSPATES BODY HEAT" with Dissipates spelled wrong! Where is this thing made? Ah.. "CHINA" on a severely crumpled tag inside the cover. It also says the cover is “70% Polyester 30% Viscose Made from Bamboo”. But the Photo shows "Bamboo" in large green letters on the cover along with "VaVerto" in much LARGER grey letters above that. The only letters on my case are the bottom part of a "b" with two "oo" next to it, in a grey-green color, extending from the side seam. NO actual WORDS at all. And the cover looks identical on both sides. Okay, it's been well over 4 hours in a very warm room, now 80 degrees with the sun pouring in, and it has mostly expanded, but I can still almost touch my fingers together when pinching the thickest part of the pillow, there is still only about ¼” of foam between my fingers. I would describe that as EXTREMELY SOFT. In the actual description of the product, on the Amazon page, if you open the "Features & Specs" it shows "Item Firmness Description - Medium" NOT what the headline says for the product: "Vaverto Small Memory Foam Bed Pillow for Camping - Compressible Medium Firm, Breathable Cover, Machine Washable, Ideal Backpacking". If I weren’t bedridden in a nursing home this would go back immediately, but it is very hard to get the staff here to help me return ANYTHING that needs to be taken to a store or kiosk. So I may just be out $22.07. FINAL Impression: WHAT A MISTAKE THIS WAS! EXTREMELY SOFT, OFFERING NO SUPPORT AT ALL! (PHOTOS ARE NOT ACCURATE to the product!!)

Comfy, but not Cooling
Comfy for a stomach sleeper, but doesn’t stay cool as promised by other reviews.

Meh. Not impressed but not the worst.
Size: King (Pack of 1), Style: Single Pack, Size: King (Pack of 1), Style: Single Pack
TL;DR: Not worth the money I’ve had quite a few cooling pillows and, while not the worst, this is also not the best in my experience. First, I had to take the cover off. It was ridiculously thick, thereby negating any cooling effect that I could feel. With the cover removed, the cooling sensation is noticeable when laying your head on it and it lasts for a minute or so. On the bright side, when the cooling feeling completely dissipates, the pillow doesn’t feel hot like some others. Having to lay on it without the cover makes it less comfortable because of the encasing material. Other than that, I’d rate the support and comfort as mediocre as well. Not worth the money in my opinion, maybe if it was about 33%-50% less.

Firm yet comfortable
We have purchased several of these pillows over the past few years. They have held up well and held their shape and firmness, even with washing. They are the right height for neck comfort and we do not need to double up pillows anymore to get a good night's sleep. They are also a good firmness to rest against while sitting up in bed.
