Came with its own pillowcase, but regular ones fit just fine too. It has a soft side and a firm side, both clearly labeled. No complaints, solid purchase.

Good

Tried another pillow someone recommended for side sleeping, worked ok. Then my chiropractor told me about pillowblox (he uses it himself), so I gave it a shot… and I love it. Finally sleeping better and deepert.

Really good support for your shoulder, neck, and head if you’re a side sleeper. Keeps everything in place. If you end up rolling onto your back, your neck’s gonna be at a weird angle though, so yeah… try not to do that.
It feels kinda stiff at first but softens up once you chill on it for a bit. No pressure point issues, and it doesn’t get hot either.
Also, regular pillowcase fits fine, no need to buy from them.

Been using this pillow for about two months now, and seriously, no more neck or upper back pain when I wake up (thank God). I sleep on my side, and at first the cube felt kinda weird, but after a few days, I got used to it and the pain just went away. Honestly, best pillow I’ve ever bought. And I’ve burned through a ton of pillows before this one.
