Is the GhostBed 3D Matrix a Good Mattress for You?

Before we get into the nitty-gritty, I want to give you a brief overview of who this GhostBed might and might not work for. Take a look at the lists below to see if this GhostBed 3D Matrix could be right for you.

Who I recommend the 3D Matrix mattress for

  • First and foremost, I’d say this bed is great for hot sleepers. It uses a special gel polymer to draw heat away from the body and adjust to your shape. That means it should sleep super cool.
  • The 3D Matrix could be great for back and side combination sleepers. It has a soft feel and is nice and responsive, so you’ll feel more “on top of” than “in” this bed.
  • Couples could also really like this mattress. You shouldn’t feel overly disturbed by a restless partner or pet on the 3D Matrix.

Who I don’t recommend the 3D Matrix mattress for

  • Stomach sleepers might not get the support they need on this bed. These folks tend to do best with firm support that helps keep their hips in alignment with their shoulders. I’d point them towards our best mattress for stomach sleepers instead.
  • Heavier sleepers (over 250 lbs) will most likely fare better on a mattress that offers firmer support. I’d recommend they check out our best mattresses for heavy people to find a better fit.
  • Folks who prefer a firm feel may not like this GhostBed, which feels soft.

What Does the GhostBed 3D Matrix Mattress Feel Like?

Now that we’ve gone over the basics, let’s figure out how this mattress feels.

Firmness is a highly subjective measure, and can change a lot depending on one’s body weight, type, and preferred sleeping position. For reference, I’m 5’9” and about 125 lbs. This particular mattress might feel softer to a lighter sleeper or a little firmer to a heavier sleeper who sinks further into its comfort layers.

After rolling around on the mattress, I gave it a 6 out of 10 on the mattress firmness scale. For reference, the industry standard for medium-firm is a 6.5 out of 10. So this is a soft to medium-soft mattress.

This mattress had a nice balanced feel that felt great on my back. Back sleepers should feel this bed filling in their lumbar region, which might be nice if gentle pressure relief helps with your back pain. Similarly, I felt a lot of cushioning around my pressure points, so side sleepers should be comfortable on this bed too.

I definitely felt more “on top of” than “stuck in” this mattress, so combination sleepers who need to move around and change positions easily at night should really like the 3D matrix. On the other hand, strict stomach sleepers could find this bed a bit too soft for their needs. I’d recommend they choose a firm mattress.

Testing the GhostBed 3D Matrix Mattress

Though firmness is important, it’s far from the only factor to consider when buying a new mattress. So, l tested the GhostBed 3D Matrix for pressure relief, edge support, and motion transfer.

Pressure Relief

When I talk about pressure relief, I’m referring to how well a bed is able to alleviate tension in the shoulders, hips, and lower back. To test for this, I like to use a pressure map.

Though it sounds complicated, it’s actually quite simple: I roll it out, hop aboard, and let the map do the rest! As I move around the bed, the map records the force my body’s exerting on it. Blue indicates areas of low pressure and red indicates areas of high pressure.

The 3D Matrix’s pressure map results.

Back — This bed felt really comfortable on my back. As I turned onto this position, I could feel the top layers of foam filling in the space at my lumbar region for some nice pressure relief. I’d also note that the bounce of the coils made it easy to move around and change positions.

Back sleeping on the 3D matrix

Side — Sleeping on my side felt good as well. The pressure-relieving foams in this mattress did a great job cushioning my joints. This mattress is still responsive, so if you’re looking for an even plusher feel I’d recommend opting for a traditional memory foam mattress.

Stomach — I could feel my hips sinking into this mattress when I turned onto my stomach. This could lead to pain over time, so I’d recommend stomach sleepers opt for a firmer innerspring mattress instead. This bed is a bit too soft for them.

Motion Transfer

Next I tested the 3D Matrix’s motion transfer, or the amount of movement detectable from one side of the mattress to the other. An important factor for all sleepers, but perhaps especially so for those who share a bed with a partner (or a rowdy pet).

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.

Considering how bouncy the mattress is, these are pretty great motion transfer results! What they tell me is that in spite of the pocketed coil system’s lift, the top layer of memory foam does a lot to dampen and dissipate motion throughout the structure. Long story short — you won’t be too disturbed by your partner’s movements in the night.

Edge Support

Finally, I tested the edge support on this GhostBed. Edge support is a measure of how supported you’ll feel if you sleep all the way on the side of your mattress.

I wished this GhostBed’s edges offered just a little more support. I felt okay when laying on the edge of the bed, but I felt like I was going to slide off when I sat on the edge of the mattress.

What is the GhostBed 3D Matrix Made of?

Next up, let’s take a look at how this bed is made. I’ll really dig into this bed’s cooling features in this section, so you’ll want to keep reading if you overheat at night.

Cover —The 3D Matrix kicks things off with a cooling cover made of Ghost Ice fabric. This soft cover actually felt cool-to-the-touch. A lot of mattresses advertise this feature, but the 3D matrix really delivered.

3D Matrix Polymer Layer — Below the mattress cover is a special gel polymer layer. The gel polymer actually attracts your body heat and then drives it out of the bed, instead of trapping it in foam layers. This is what really ensures this bed sleeps cool. This gel is also soy-based and eco-friendly.

Comfort Layer — Up next is a layer of gel memory foam. This material has a slow response to pressure, which allows the sleeper to sink in for some pleasant relief at the shoulders and hips. Though memory foam has a slight reputation for overheating at night, the gel-infusion helps dissipate heat.

Ghost Bounce Layer — Up next is a bouncy layer of latex-alternative foam. Like latex foam, this layer is dense and responsive, and it helps lift the sleeper up and out of the bed.

Transition Layer — Below that is a layer of transition foam. It helps ease the sleeper down into the pocketed coils below, and adds a bit more responsiveness.

Support Layer — The mattress’s support core is made of individually wrapped coils. These springs are highly responsive, infusing the mattress with some fantastic bounce. They also help promote airflow throughout the mattress, making it even more breathable.

Base Layer — Rounding things out is a thin layer of high-density foam. This material mostly serves to give the coils above it something to bounce off of.

My Final Thoughts about the GhostBed 3D Matrix Mattress

Well, we’ve officially reached the end of this review, and now it’s time for you to decide if the 3D Matrix is the bed for you! Though I can’t make the decision for you, I can leave you with a few final thoughts to help you get there on your own.

My favorite things about the GhostBed 3D Matrix mattress

My favorite thing about this bed-in-a-box mattress is its temperature regulation. This mattress sleeps super cool, and I think that’s a huge bonus for any hot sleepers out there. I also really appreciate the 3D Matrix’s ability to isolate motion. That and its cooling abilities should make this mattress a great choice for couples.

I also appreciate the soft feel of this mattress. I think other side sleepers will also enjoy the cushioning feel of this GhostBed’s foams.

My GhostBed 3D Matrix mattress complaints

I wish this mattress offered a little more edge support. I also think heavier sleepers and stomach sleepers might find this mattress a bit too soft for their needs. The softer feel of this mattress could impact its durability for heavier sleepers.

The 3D Matrix is a little too soft for stomach sleepers.

I’ll also note here that a few customers found the GhostBed’s cover a little slippery. Some folks mentioned that it was hard to keep their fitted sheets on the bed. I’d recommend adding a mattress protector to the bed to get a little extra traction if you run into this issue.

GhostBed 3D Matrix Mattress Vs

Still wondering if a different mattress might be better for you? Below I’ll compare the GhostBed 3D Matrix to two of its online mattress competitors, the original Purple mattress and the Original Casper mattress.

GhostBed 3D Matrix Mattress vs Purple Mattress

  • Unlike the GhostBed, the Purple is an all-foam mattress.
  • The Purple feels firmer than the GhostBed, which could be a bonus for back sleepers who prefer a firmer feel.
  • Like the GhostBed, the Purple mattress uses a special polymer. While the GhostBed uses a cooling gel polymer matrix, the Purple uses a hyper-elastic polymer grid to provide pressure-relief in multiple positions.
  • Interested in this bed? Learn more in the full Purple mattress review.

GhostBed 3D Matrix Mattress vs Casper Mattress

  • The original Casper is an all-foam bed-in-a-box option.
  • The Casper feels firmer than the GhostBed, and offers zoned support. This means it’s firmer at the hips but softer at the shoulders, which could be a perk for those who suffer from back pain.
  • The Casper mattress is cheaper than the GhostBed 3D matrix, which is a bonus for value shoppers.
