We are so happy

We love our bed so much. It's worth every penny. We were tired of buying a new bed every 2-3 years. King Size beds cap in the middle. This bed does NOT. We are so happy with our purchase.

Better sleep quality

My wife and I were sold on a leading foam mattress until we looked and laid down on an INTELLIbed. We both thought we preferred a super soft and foamy bed. That all changed as we laid down on the INTELLIbed because we noticed almost immediately that although a bit more firm than we were accustomed to we both had no desire to reposition due to pressure points. Both of us have noticed better sleep quality and more energy throughout the day! We are 3 weeks into our ownership of an INTELLIbed and our only regret is not getting this about 15 years ago!

A cooling treatment is applied to the fabric of the outer cover and to an inner liner to provide a surface that will dissipate heat for a cool night's sleep.


A special foam comfort layer provides enhanced relaxation and comfort.
