    You Want to Hear about My Dreams?

    Well, it started off when I was a young girl...

    I'm joking. :)

    The pillow cube is amazing! I recently participated in the contest and won this new pillow. I am SUPER excited that I actually won something and it wasn't a scam/spam e-mail saying I would have to pay in gift cards. I had already bought two pillows (both side cubes), for my husband and myself. So getting this one was great. I offered, to my husband, that we could give it, as a birthday gift, to a relative (their birthday is coming up) and he said this pillow is TOO GOOD to give away and we must get more, to hoard, and eventually make a pillow fort with PillowCube's pillows. I thought his response was hilarious and wanted to share it with you. Also, we now have the three pillows all across the top of our PillowCube's Mattress Deluxe, king sized, mattress. I will definitely be back to order more and maybe win more? :D (Hopefully!) To eventually have that PillowCube pillow fort. (We are in early 30's, but yes, we are still children, lol)

    Thank you so much PillowCube!!

    Standard 5" Pillow Cube

    We slept on this pillow when we visited our son. We both slept well for the two nights we were there. He has normal shoulders for a man, but I have wide shoulders for a woman. After those good results we purchased them for home and have been very pleased with them. While they were more expensive that our other pillows, they have proven worth it.

    Outstanding sleep!

    I’ve been sleeping on my Pillow Cube for over two weeks now and I have been able to track my better sleep on my fitness watch. I’m no longer waking up in the middle of the night, multiple times, to adjust my “normal” pillow, my stiff neck has gone away and I’m sleeping through the night not tossing and turning. I highly recommend this to any side sleeper who wants a better night’s sleep.
