On a mission to bring customers the ultimate in customizable comfort, new mattress company Morphiis has launched its flagship adjustable bed. Featuring an all-foam design that can reportedly be manipulated to have 64 different firmnesses (!), this mattress is meant to satisfy a wide range of sleepers.

But just how well does the Morphiis live up to this aim? I won’t know until I put it through my series of rigorous tests to assess its unique feel and figure out whether or not it could be the bed of your dreams! I should note that while you can orient this bed to really have whatever kind of feel you want, for the purpose of this review, I’m only looking at the medium firm iteration.

CONSTRUCTION

As I mentioned up top, the all-foam Morphiis claims to have a total of 64 different firmness options, which would make it one of the most customizable beds on the market. The way it works is this: the mattress arrives at your door with a hollowed out middle section filled with 12 “medium firm” foam blocks, which you can then swap out tetris-style with the other adjustable foam inserts you receive.

These inserts come in yellow (soft), blue (medium) and white (firm), allowing you to mix and match with different feels throughout the structure. And if this sounds intimidating, don’t worry—the Morphiis website does feature some standard patterns you can follow.

Curious to see how all this comes together? Me too! So let’s dive on into this bed.

Cover – The cover is made up of a soft cotton/polyester blend. It’s both breathable and stretchy, allowing for excellent airflow throughout the mattress without bunching up as you move around.

Comfort Layer – Built with the brand’s proprietary ULTRAFOAM, the comfort layer is super soft, providing the sleeper with some immediate comfort. While the material is certainly gentle to the touch, it also has a quick response to pressure, which should keep you positioned on top of the bed.

Customizable Layer – Directly below the comfort layer, you’ll find the customizable section we discussed up top. Featuring a ring of edge support and a hollow middle, you can fill up this layer to your heart’s content with 12 of the provided foam inserts. The bed is going to arrive with these inserts arranged in the medium firm orientation, but you can shift them around as need be.

Personally, I found it quite easy to interchange these inserts. They slip out without much effort and lock into place well once you’ve got everything settled.

Base Layer – The base layer is comprised of high-density poly foam, functioning mainly to support the adjustable section above and give the bed its shape. What’s unique about this section is the interesting diamond cut along its bottom, which was designed specifically to work with an adjustable base.

FIRMNESS

After taking a look at the construction of the Morphiis, let’s chat about the firmness and feel. I started off by applying light hand pressure to the mattress and found that I was mostly interacting with the soft ULTRAFOAM in the top layer. While this section did provide me with some pleasant comfort, I also noticed that it was pretty bouncy, which helped to lift me up and out of the structure.

Since people of different body types and shapes are going to feel firmness differently, I decided to bring in three other testers to help me figure out just how firm the Morphiis is. We all took a quick rest on the bed, decided on our personal firmness ratings and then tacked them onto the graph below.

While firmness is always going to be an individual thing, this will hopefully give you a better sense of the range you can expect from the mattress.

As you can see on the graph above, my testers were mostly in agreement about the firmness of the Morphiis, giving it an average rating of 6. When compared to the industry standard of 6.5 for medium firmness, this iteration of the bed appears to be just a touch softer than medium firm.

I personally gave the mattress a 6, finding it to be a good representation of a medium firm feel. While this rating would likely change if you were to configure the inserts in a different manner, I should note that you’re not going to be able to achieve the firm support of pocketed coils nor the deep contouring of memory foam with this bed simply by nature of its construction.

This isn’t necessarily a bad thing, though, as the subtle, responsive feel of the Morphiis’ poly foam could be quite satisfying for someone in the market for a more neutral vibe.

EDGE SUPPORT

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

Morphiis Back

As you can see in the photo above, once I scooted as close to the edge of the bed as I possibly could, I began to detect some compression through the soft top layer. However, I would say that the transition and base layers held up fairly well, leaving me feeling solid at the side. All in all, I found the Morphiis to have pretty average edge support consistent with other all-foam mattress I’ve tested.

PRESSURE MAP

When buying a new mattress, you’ll definitely want to keep an eye on pressure, specifically where pressure points are going to form while lying on top of it.

To help you visualize these pesky tension spots, 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 – Lying on my back, I felt as though my weight was pretty evenly distributed. The top comfort layer did an excellent job of filling in the space at my lumbar region for some nice pressure relief, which you can clearly see in the graphic above. I should add that I found it easy to change positions and never felt stuck in the bed.

Side – Rolling onto my side, I continued to feel quality relief from this bed. The ULTRAFOAM in the comfort layer contoured nicely to my shoulders and hips, typical problem areas for side sleepers. However, since those who doze strictly on their sides tend to prefer even softer mattresses, I’d suggest swapping out a few of these blue medium firm inserts for the softer yellow ones.

Stomach – With the Morphiis oriented in this medium firm feel, I definitely felt my hips sinking into the structure, which isn’t always a great thing for stomach sleepers as it means their spines have been bent out of a straight alignment. That being said, I’d recommend swapping out some of these blue inserts for the firmer white ones if you primarily sleep on your stomach.

MOTION TRANSFER

Another important factor for couples to consider when getting a new mattress is motion transfer, or the amount of disturbance you’re likely to feel from one side of the bed to the other.

To illustrate this motion transfer, I dropped a 10 lb. 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.

FYI: Each drop is meant to symbolize a different movement you’re likely to experience in bed, from tossing and turning (4”) to getting out of bed (8”) all the way to full on jumping (12”).

While I was impressed with the four inch drop, I’d say that the other motion transfer results are just about average, which makes sense considering the responsive foam used in the bed’s construction. What this means is that you’re likely to feel movement across the surface of the bed, though I’d reckon the disturbance won’t be too dramatic.

SINKAGE TEST

Next up, let’s chat sinkage! This test is meant to demonstrate whether or not you’ll feel like you’re sinking “into” the Morphiis or lying “on top” of it.

To visualize this sinkage, I placed four balls of varying sizes and densities (a 6 lb medicine ball, a 10 lb steel ball, a 50 lb medicine ball, and a 100 lb 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 lb medicine ball: 1.5 inches of sinkage.
  • 10 lb steel ball: 2 inches of sinkage.
  • 50 lb medicine ball: 4.5 inches of sinkage.
  • 100 lb medicine ball: 6.5 inches of sinkage.

Compared to other all-foam mattresses I’ve tested, these are pretty intense sinkage results! What this tells me is that you’re likely to feel yourself sinking pretty far into this bed, which could be a great thing for those of you in search of some deep pressure relief. However, I’d say that these results are a bit misleading, as they suggest that you’ll feel “stuck” in the mattress, which I personally never did.

I’ll remind you too that these are the results for the “medium firm” configuration, so you can expect a little less sinkage from the “firm” orientation and a little more from the “soft.”

IS THE MORPHIIS MATTRESS RIGHT FOR YOU?

Now that we’ve taken a closer look at the Morphiis mattress, I want to highlight some of its biggest pros and cons:

PROS

  • Given its adjustable nature, I think this mattress could make a solid pick for couples, especially for those made up of people with different sleep preferences.
  • Another fantastic selling point for this bed is its customizable zoned support. If you need specific, targeted relief at a certain part on your body, this could be a nice mattress for you.
  • And finally, this adjustable bed is also going to work well with the brand’s adjustable base thanks to its convoluted bottom design. That way, you can get fully customizable comfort all the way through.

CONS

  • If you’re looking for a bouncier supportive vibe (the kind you might get from an innerspring or hybrid model), the balanced foam feel you’ll get with the Morphiis may not work for you.
  • Another significant con is that you can detect a bit of space between the adjustable foam inserts, which won’t be an ideal feel for some of you.
