LOVE this pillow!!!! I have 2!!!!
Size: Queen (Mid Loft), Number of Items: 1
Well…..I have a love affair with these latex pillows. I purchased 2 of them. I have been allergic to feathers since birth and could only use latex pillows growing up. But, they became very hard to find for many years. I tried all the other kinds of pillows on the market and hated them all!!! “Won’t go flat!”….. whatever! They would go flat almost immediately. Or “Good for side sleepers!”….. NOPE!! I had a stiff neck for a week!! DONE with all of them. So,I finally got on Amazon and found this pillow. Ahhhhhh!! Loved it. Slept like a log! All night! Didn’t go flat!! No stiff neck!!! A winner!!!! Frankly,I don’t care about the cost… yeah…I know….we call have to count our change……including me. I saved to buy this pillow…..both times. AND, I would do it AGAIN!!!! And…proud to do it! So, if you have had it with all of those new prefangled so-called pillows…try this one. I would only avoid it like the plague if you are allergic to latex. Otherwise,I would definitely recommend this pillow! Wherever I go….my pillow goes. Camping, on a trip, to visit relatives…..my pillow will travel!!!!

The Perfect Pillow
Size: Queen (Low Loft)
Finally found the right pillow for me. I have purchased quite a few latex pillows attempting to find the right one. I was apprehensive due to the support description being "extra soft". Yes, it's super soft when you pick it up and squeeze it, but it provides the perfect amount of support for side and back sleeping.

Absolutely awesome pillow! My sister and I used to have pillows like these as kids and always look to replace them. These are wonderful. Cool and comfortable and the perfect amount of firm and support . Spouses fight us for them!!

Nice foam latex pillow. A little thicker than I wanted, but has improved my sleep quality

Just what we were looking for.
Been buying these latex foam pillows for years. Definitely less firm due to it being “extra soft”. Soft and still somewhat supportive. Is not hot either. So glad I can still buy these pillows.
