Pillowriffic
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
These pillows are exactly as described, I would say they are softer than I expected but still very good. They come compressed so it will take an hour or so for them to fill up so you will want to open these before bedtime. All in All if you are looking for a reasonably priced pillow that will last a couple of months I would recommend these.

Great buy
Color: White, Size: Queen (Pack of 2)
I was very skeptical about buying pillows online. I am pleasantly thrilled with these pillows. They are great quality. They maintain their shape by simply shaking occasionally if needed. The fabric is really soft to the touch. They don't go flat after a few uses. I've had them for almost 6 months. I waited to review to make sure they didn't disappoint.

LOVE THEM!!! SAVED MY NECK!!!
Color: White, Size: Queen (Pack of 2)
Hallelujah!!! After spending so much money on pillows that didn't work for my aching neck and shoulders, I finally found pillows that works for me and I am SOOOOOO excited. I had my 1st night of comfortable sleeping after years of restless, painful nights. These pillows are the BOMB! I kid you not. I have spent hundreds of dollars on pillow to no avail. I mean, the expensive hotel pillows that were suppose to make you feel as if you're sleeping on clouds made my neck stiff and painful. Let's not talk about that "infamous pillow: advertised on the infomercial that was suppose to be the #1 pillow to fight against neck and back pain. Shhhh, we won't say the name but uh....TRASH. Ok, I'm back. Lost it there for a moment thinking of all the money I wasted on all those pillows that claimed to be "THE PILLOW." LOL..what a joke. So, anyway back to what I was saying about this pillow beauty. The very 1st night I slept on it, I'll admit I was skeptical when I laid down. Scared I was going to wake up with a sore neck and headache to go along with it. I tore the package open, let the pillow inflate, fluffed them with my hands and allowed them to sit for a few hours. I didn't wait the allotted time suggested because I was too anxious to try them and it was almost my bed time. So, excitedly I jumped in bed, laid my head down on the pillow and immediately thought, "oh no, these are too soft. This will not work." I just knew I would wake up to a sore neck. Cautiously, I laid down and waited to drift off, dreading waking up the next morning with a stiffer. (LOL) To my surprise I actually slept all night too. I usually would wake up like a thousand times fighting with repositioning the pillow to find my comfort zone. WOW, not that night. I slept like a baby and wait for it.....I woke up the next morning with NO PAIN! Hallelujah! I couldn't believe it. I was literally pain free in my neck and did not have a headache from the strain on my neck, shoulders and back. Man, is this really happening, I asked myself. This just can't be real. Wake, wake girl. You are dreaming. But nope. I was fully awake and with a pain free neck and shoulders. I jumped up and started getting ready for my day. I finally found the pillow that I wish I had found years ago. Could have saved so much $ from going down the drain. I am SO thankful to all the reviews that I read that shared their positive experience and encouraged me to purchase for myself. I am SOOOO GLAD I took a chance and brought these little beauties. They saved my neck and my sanity. Thank you EIUE Hotel Collection for inventing the pillow that is reasonably priced and that does the job it's intended to do. Allow people to have a good nights rest WITHOUT neck, shoulder and back pain. Your Rock! This is a real review and I am a real person.

They are long pillows but definitely flat, I tried and tried to fluff them up and they are about like the $3 Walmart pillows. I will be returning these
