GoodBed Expert Review
Our Take on Beautyrest World Class Level 4 Medium

Founder of GoodBed, Leading Mattress Expert
- Want a medium-firm mattress (i.e., just a little firmer than average)
- Are mainly a back sleeper
- Often sit or sleep along the edge of your bed (edge support is very good)
- Prefer a slightly above average amount of 'memory feel'
- Like a little bounce in your mattress, but not much
- Enjoy a happy medium between sleeping 'on' your mattress versus 'in' it
- Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)
- Want a natural or organic mattress

Yes, the Beautyrest World Class Level 4 Medium mattress is adjustable base compatible. This means it is designed to be used on an adjustable base without incurring damage or voiding the warranty. In our review of this mattress, we tested it on an adjustable base to look for any adverse effects as the head and foot are elevated, and to see how well it conforms to the contours of the base both with and without the weight of a sleeper. Overall, we found the Level Four Medium to have good adjustable base compatibility.
