Pressure Test Results

The L-Class Medium Pillowtop mattress has been pressure tested with petite, average, and large body size models laying on their side and back sleeping positions to see what kind of support and comfort you can expect. (Learn how we test.) 

Our test results show that this mattress performed very well in relieving pressure on the joints while also providing great back support.  The bed earned 5 out of 6 'recommended' scores based on the data learned from the images below.  To understand what we're looking for you'll need to decipher the colors you see.  Green and light blue areas show you where the mattress is providing good back support and peak pressure point relief.  Yellow areas indicate an increase in pressure while red areas, of which there are none in the images below, show where there's far too much pressure on that joint.

This bed is really good at providing proper back support for correct spinal alignment.  This is especially important because an out of alignment spine will cause discomfort, pain, stiffness, and weariness.  Pressure point relief is pretty crucial to quality sleep as well because too much pressure will cause you to toss and turn at night thereby disturbing your sleep and making you grumpy the next day.  This bed provides excellent pressure relief for all body types and sleep positions, as well.  Feel free to use our test results when considering this model mattress as your next bed purchase:

The Black L-Class Medium Pillowtop mattress is an important model in the Black Collection because it's the lowest-priced pillow top mattress they offer.  It provides pressure-relieving capabilities and back support for all body sizes and sleeping positions.

The mattress is a relatively expensive mattress so you'll want to know if it's worth the premium price.  It does have BlackICE with Plant-Based Cooling Technology on top of multiple layers of Medium Comfort Foam.  In total it has 4 3/4" of Medium and Plush Comfort Foams making it a bed that's taller than average.  Beautyrest uses premium foams in this construction which is a plus.  The foam layers rest on its Zoned T3 Pocketed Coil.  A sophisticated coil design helps you feel the softness and still get firm support under the heaviest parts of your body.

The top layer of the mattress has the BlackICE with plant-based cooling technology material as noted above.  This material is important because it helps remove excess body heat away to create a cooler environment so you can sleep better.  

These are all premium materials that you get for the price.  It's a good value at this price based on what you get.  The mattress is medium in feel, so it'll appeal to most people, and with the cooling and supporting features we've noted you can make a good choice with this mattress.
