Beautyrest Black K-Class Firm Pillowtop Mattress Review
Updated June 11, 2024
If you're considering the top-of-the-line firm feeling mattress from Beautyrest Black, read this review for more insight into whether this bed is right for you. The K-Class Firm Pillowtop is a high quality firm model. In this review, we detail how it's made and we'll also publish our first-hand pressure tests in the near future.
Comfort Scale Rating
The K-Class Firm Pillowtop mattress has a firm feel; we rate it a 3 on our 10 point Comfort Scale (a 1 is hard, 10 is softest.) This is what we call cushion firm, where it does have a firm feel but with a good amount of pressure relief still. We also carry a plush option.

Pressure Test Results
We will pressure tested the K-Class Firm Pillowtop mattress and will publish our results soon. We test it 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.
We do our pressure tests to see how the mattress performs in those different sleeping positions with various body-sized people. We can see if there are painful pressure points or areas lacking proper support. Both of those things can ruin your sleep and we find the testing we do shows real insight into how a mattress will perform. This mattress is very tall with many layers of materials so we'd expect it to do pretty well when we publish our results.
Below is a sample of what a pressure test looks like. We'll update our review after we pressure test the mattress and let you know how it did.
The pressure test results for this mattress are not yet available but it will be available soon. Below is just an example.
