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!!!!

Side sleeping pillow

Style: Standard - Medium

Great pillow for specific people. If you want a firm yet soft pillow for side sleeping then it works great. Not as good for back sleepers but it's very comforting and cooling.
