Editor’s Note: The Tempur-Pedic Flex Supreme mattress is no longer available, but Tempur-Pedic has many more models to offer.

The name Tempurpedic is synonymous with the world of memory foam. The company has been churning out its popular line of cloudlike mattresses for over two decades now and shows no signs of stopping any time soon.

Enter the Tempur-Flex Supreme, one of the brand’s more recent innovations, which fuses the pressure relief of memory foam with the supportive oomph of innerspring for an all-encompassing hybrid sleeping experience.

Given the intriguing combo of materials used in this baby, I was eager to try it out for myself to see just how comfortable it truly is.

See how the Tempur-Flex Supreme ranks on my best hybrid mattress list!


The Tempur-Flex Supreme features a hybrid construction, which means it combines the best of both innerspring and memory foam technology. Here, an interior section of pocketed coils is surrounded by layers of foam, and the interplay between the two materials is what provides the mattress with its support and pressure relief.

Now let’s dive into each of these different layers.

Cover – The cover is made of a soft polyester spandex blend. It’s stretchy, but snaps back into place quickly, which means it won’t bunch up when you’re moving around at night. An added bonus is that it’s removable by zipper, so you’ll be able to throw it in the washer with the rest of your bedding.

Comfort Layer – Built with 2” of memory foam, the comfort layer is soft to the touch and slow to respond to pressure. True to the material, this layer will contour snugly to the body and provide the sleeper with some cozy pressure relief.

Compression Layer – Below the comfort layer we find the Tempur-Flex’s compression layer, which is comprised of an inch of memory foam. This section is a bit firmer than the top layer, but works in tandem with its upstairs neighbor to produce the classic sinking feeling associated with memory foam. This layer also acts as a transition to the wrapped coils below.

Support Layer – Speaking of springs, the core of this mattress is constructed with 6” of pocketed coils. They’re individually wrapped, so they move independently of one another—this flexibility allows the body contouring of the memory foam to extend throughout the bed. The bounce of the springs also counteracts some of the sinkage of the foam, so you’re not going to feel stuck in the mattress. I should note that these coils are surrounded by polyfoam edge support, which contains them and reinforces the frame at the sides.

Foundation Layer – The base is made of 2.5” of high-density polyfoam. This layer acts as the foundation of the bed, giving it its shape and cradling the bouncy coils.

After taking a look at the construction of the Tempur-Flex Supreme, let’s chat about its firmness and feel. I started off by applying some light hand pressure to the mattress and was immediately greeted by the memory foam, which gently hugged my hand. As I pressed in further, I could feel the bounce of the coils, a supportive feature that lifted me out of the bed.

At this point I’d like to note that people of different body types and shapes will feel firmness differently. Rather than giving just my opinion on the overall firmness level of the Tempur-Flex Supreme, I enlisted three other people to give their opinion as well. This will give you a better sense of the firmness range you can expect from the mattress.

As you can see in the graph, my testers reported ratings in the 6-7.5 range with an average firmness score of 6.6, a mere hair above the 6.5 industry standard for medium firmness. This ranking is consistent across most hybrid mattress models, which borrow from the cushiony goodness of memory foam and the buoyancy of steel coils.

I personally gave the Tempur-Flex Supreme a firmness ranking of 6, which I’d categorize as a medium firmness. You’re going to get the pressure relief benefits of memory foam without that “stuck in the mattress” feel that you sometimes get from the material, thanks to the sturdy coils in the core. These bad boys are going to support you and make you feel like you’re sleeping “on top” of the bed as opposed to in it. This works for a wide range of sleepers, especially those who snooze in multiple positions.


Rather than just describing the feel of the Tempur-Flex Supreme to you, I wanted to give a visual representation of where someone may feel pressure points form while lying on it. To do this, I placed a pressure map on top of the mattress and lied on my back, side and stomach. You can see the results on the image below where pressure is represented from blue (low pressure) to red (high pressure).

Back – As you can see in the graphic above, I felt relatively low pressure while lying on my back. The memory foam provided quality pressure relief to my lumbar region and the wrapped coils allowed me to roll around easily.

Side – Turning to my side, I felt some pressure at my shoulders and hips, but not in an uncomfortable way. While a traditional innerspring mattress isn’t always ideal for a side sleeper, the added bonus of memory foam in this hybrid helps to alleviate any discomfort.

Stomach – Switching to my stomach, I felt nicely supported and didn’t experience any awkward pressure. The springs helped to raise my hips out of the mattress and kept my back from collapsing into an unhealthy shape.

If you plan on sharing your bed with a partner, you’ll want to know what it’ll feel like when the other person crawls out of bed in the morning or tosses around at night. This next test is intended to demonstrate the intensity of motion that is detectable from one side of the mattress to the other.

To illustrate this motion transfer, I dropped a 10-pound steel ball from heights of 4 inches, 8 inches and 12 inches and measured the disturbance it caused: the bigger the lines, the bigger the disturbance.

The Tempur-Flex Supreme shows a small amount of disturbance for the 4 inch drop, which simulates someone rolling around and adjusting their position on the other side of the bed. While the 8 and 12 inch drops show slightly larger spikes, I’d say these are some of the least dramatic motion transfer readings I’ve ever seen. Though innerspring mattresses aren’t normally the best at containing motion, the foam outer layers help to dissipate and control any movement, making this a fantastic bed for couples.


When buying a new bed, most people want to know whether they’ll feel like they’re sinking “into” the mattress or laying “on top” of it. To visualize this sinkage, I placed four balls of varying sizes and densities (a 6-pound medicine ball, a 10-pound steel ball, a 50-pound medicine ball, and a 100-pound medicine ball) on the mattress and measured how much they compressed the surface.

The variations in size, weight and density are meant to simulate different body parts and different sized sleepers.

  • 6-pound medicine ball: 1.5 inches of sinkage.
  • 10-pound steel ball: 2.5 inches of sinkage.
  • 50-pound medicine ball: 4.5 inches of sinkage.
  • 100-pound medicine ball: 6 inches of sinkage.

While you’ll definitely experience some slight sinkage from the memory foam comfort and compression layers, the interior coil structure offers enough support to leave you feeling like you’re sleeping “on top” of the mattress as opposed to in it. This is great for most sleepers, especially if you sleep primarily on your back or stomach.


If you’re going to share your bed with a partner and need to use the entire surface area of the mattress, it’s going to be crucial for you to consider the amount of edge support it’ll provide.

Lying on my back, I felt super supported by the Tempur-Flex Supreme. The high-density polyfoam does a great job standing up to pressure, so you’re going to feel as solid in the center of the mattress as you do nearer the edge.

I found that it was easy to roll around and change positions, most likely because of the supportive coils in the core. As I rolled onto my side, the mattress experienced some light compression, but nothing major.

In this position, I wanted to simulate what it would feel like to be sitting on the bed in the morning when you’re lacing up your shoes and getting ready for the day. The Tempur-Flex Supreme performed well on this test as I didn’t feel like I was sinking into the bed at all.

Now that we’ve taken a closer look at the Tempur-Flex Supreme mattress, it’s time to discuss who it’d be a good fit for.

  • Looking for a hybrid mattress – As I’ve outlined above, there are a lot of things to enjoy in a hybrid mattress, namely that you get both the pressure relief of memory foam and the support of innerspring. If you’re eager to try out that feel, this mattress would be great for you.
  • Sleep in multiple positions – Given the combo of materials used, this bed is great for sleepers who like to sleep in multiple positions. You’ll feel comfortable on your side because of the memory foam top layers and supported on your back because of the individually wrapped coil interior structure.
  • More comfortable with big name company – Tempurpedic has a strong reputation in the mattress world, so if you’re more comfortable going with a name you’ve heard of, the Tempur-Flex Supreme could be the perfect pick.

Layers of memory foam and coils come together to create a responsive feel with balanced levels of support and comfort.

That said, the Flex Supreme Breeze still offers high levels of pressure relief and great cooling. If you’re looking for an ultra-luxury hybrid mattress and have no budget, the Tempurpedic Flex Supreme could be a fine choice.
