The Beautyrest Black C-Class Plush mattress is a "mid-range" bed in the Black Collection. It's more expensive than typical beds as it is at the high-end of Beautyrest. We've reviewed it ourselves, along with testing it, and you can read our take on the mattress below:

Comfort Scale Rating

The C-Class Plush mattress is soft, but not too soft; we rate it a 6 on our 10 point Comfort Scale (a 1 is hard, 10 is softest.)  It is a soft mattress, so it will appeal to you if you like this kind of bed.  However, if you like medium or firm beds then you should consider another choice.

Pressure Test Results

We tested the C-Class Plush mattress with petite, average, and large body size people on their side and back sleeping positions to see what kind of support and comfort you can expect. (Learn how we test.) 

Given this mattress has a softer feel, and it's a luxury mattress with many layers of cushioning the testing results showed that this bed is a great choice for most people.  There are minimal pressure points that showed during testing which is good because discomfort in your joints causes you to toss and turn throughout the night.

Below are the visual results of our testing for your consideration, please examine them if you're considering the C-Class Plush mattress as your next bed:
