Bed pillow
The best pillow for people who have a hard time choosing a pillow. Pricey but worth it. Love the way I can conform it to my liking.

Packaging for shipping = terrible. Pillow = 10 stars
The pillow is great; the shipping/packaging not so much. Normally Amazon warns me if an item is being shipped in manufactures packaging and gives me an option to choose to have it boxed in Amazon packaging; I was not given that warning or option for this item. I am honestly confused why anyone would think shipping a pillow in just its vinyl store packaging “dust” cover would be a good idea. The vinyl cover arrived fully damaged. Cuts from what look like a box cutter, the handle 1/2 torn off, the zipper was 1/2 unzipped… Thankfully the pillow was not damaged or this review would be much different; but honestly who ships a pillow of any price point in a 10mil vinyl dust cover? About the pillow. My young adult child has been using a Bedgear pillow for about 9 years…the same pillow actually. It has stayed in a waterproof pillow cover inside a pillowcase that gets washed weekly, and the pillow has held up great. Recently I noticed the pillow was being used without the 2 covers and had gotten something spilled on it. Since the pillow is spot clean only and the inner foam is not submersible in water I decided it was time for a new pillow. Their original model was the original Summit but since they toss and turn and then end up on their stomach we decided to try the Multi position this time. They have slept on the pillow for 3 nights now and seem extremely happy.

Best one so far
Still on the never ending quest for the perfect pillow. Must say that for the price this one can't be beat. Not willing to invest a small fortune on a pillow and this one is extremely reasonable
