Best Sleep Of My Life With This Pillow!

Honestly I'm very picky with pillows, all my family members have loved really soft pillows but I always went for firm ones because otherwise my neck hurt every morning. But then in early 2021 I saw an add on Instagram and bought a pillow cube soon after. Now I've had it for over 2 years, much longer than I've been satisfied with any other pillow. Now I'm considering buying another one for when I stay over night at my boyfriend's place cause he likes soft pillows just like everyone else in my life 🤣

Supportive Pillow - Good For Side Sleeper

As a side sleeper, I was constantly plagued by neck and back pain upon waking. I wanted to hold off on sharing my thoughts until I'd thoroughly tested out this Pillow Cube. Having used this product for several weeks, I can confidently say that it has resolved all of my discomfort issues. My first order was for the standard size, but it was too tall for my preference. However, the return process was not only seamless but also environmentally friendly, which I truly appreciated. For reference, I'm 5'3 and weigh approximately 110lbs. I found that the 4-inch version of the Pillow Cube suits me far better.

Does Exactly What I Hoped It Would Do

I’ve suffered from neck problems for many years, and frequently wake up with muscle spasms which, in turn, often triggers migraines. I knew that my old pillow wasn’t working for me, but had no idea what to try as a replacement. After my wife and son both bought Pillow Cubes and raved about them, they convinced me to give one a try. Although it took a night or two to get accustomed to the extra support, I have not had any neck pain whatsoever since I started using it, and I find that I’m sleeping more soundly than before. The Pillow Cube is definitely worth every penny spent - I just wish I had it years ago.

    I was worried it would be too thin

    I’m 5’1 and followed the instructions to buy the thin pillow. When it arrived, it seemed really thin! But it has been absolutely perfect to sleep on! I am very happy with how comfortable this pillow size is for me and I encourage everyone to follow the instructions and get the size that is truly right for you.
