Best rest in a long time.

I actually sleep deep enough to dream and wake up with no neck pain. It’s been a blessing. Learned about the cube from my son while visiting. He let me lay on it, and I was in awe of how comfortable it was.

Only gripe is price.

If it were $75, I’d buy 4.

Thanks for taking the time to leave a review! I suppose if you compare it to a regular pillow that will only last about 12 months or less, this may seem expensive. However, if you take into account the 3+ years that this pillow should last, that's less than 10 cents a night for more than 1,095 nights of sleep that feels like a million bucks!
