Intellibed Matrix Grand Mattress Review

I’m super stoked for this review because I’m taking a look at one of the most ~luxurious~ beds I’ve ever seen: the Intellibed Matrix Grand. Built with multiple layers of pocketed coils and plush foam, this mattress (which starts at $8,000!) is truly the grand dame of bedding. But is it actually comfortable?

To find out, I put this baby to the test, examining its construction and assessing its feel to see if it might just be the bed of your dreams.

Curious for my thoughts? Then you better keep on reading! Or, you can click here to skip down to my review summary.

Brand Snapshot

Intellibed launched in 2000 on a mission to build the bed of the future. To do this, the brand developed a proprietary Gel Matrix material, which brings a plethora of pressure relief, comfort, and contouring to its vast line of luxury mattresses. Beds aside, the company also sells pillows, sheets, adjustable bases, box springs, and mattress protectors.

But we won’t be getting into all these goodies in this review. Instead, we’ll be focusing exclusively on the Intellibed Matrix Grand mattress.

What is the Intellibed Matrix Grand Made of?

I mean, what isn’t the Intellibed Matrix Grand made of? At a whopping 17” tall (yes, that’s 1-7), this mattress is packed with a ton of different materials, including the aforementioned Gel Matrix Foam, buoyant Energex Foam, pocketed coils, poly foam, and phase change cooling technology. The mix of materials is intended to create a balanced vibe that’s as pressure-relieving as it is supportive.

But does the bed pull this off? Let’s dive under the covers to find out!

Cover – The Intellibed cover is woven with Phase Change Material, which makes it literally cool to the touch. This could be a great feature for those who tend to overheat at night.

Pillow top – The comfort kicks off with a thick pillow top layer of different foam materials. In this gentle section, you’ll find Energex Foam (a pressure-relieving poly foam that’s got a quick response to pressure for bounce and lift) and the brand’s special Gel Matrix Foam (a durable, elastic gel material that “flexes” to provide uniform relief across the body). This combination produces an interesting interplay between pressure relief and support, allowing for some nice cushioning without too much sinkage. I should also add that there’s a layer of open cell foam in this pillow top as well, which helps to further dissipate body heat throughout the structure.

Transition – Below the pillow top, you’ll land on a transitional layer of poly foam. This section helps ease the sleeper into the firm pocketed coil system below.

Base – The bulk of the mattress is made up of this section of buoyant pocketed coils, which endow the structure with plenty of bounce and support. These springs are also zoned, meaning they’re grouped so as to bring different levels of comfort to the shoulders, hips, and lower back. This could be an especially attractive feature for combo sleepers, who need to feel supported across multiple positions.

How Does the Intellibed Matrix Grand Feel?

Now that we’ve got the construction specs out of the way, let’s talk about how this baby feels, starting with an assessment of its firmness.

But before we get into my personal thoughts, I just want to take a moment to acknowledge the subjective nature of firmness. As with any feel factor, it can change a lot depending on one’s body size, shape, and weight, so my read of the mattress could be very different from your own. For reference, I’m 5’10”, 190 lbs., and sleep primarily on my stomach.

I found the Intellibed Matrix Grand to have a nice medium firmness

After stretching out on this mattress, I decided to give it a 6.5/10, which syncs up perfectly with the industry standard for medium firmness.

In my opinion, this bed strikes a satisfying balance between lift and give, with no one material overwhelming the feel of the structure. So, yes, while the Gel Matrix technology provides some pleasant pressure relief at the shoulders and hips, its softness is bolstered by the lively one-two punch of Energex Foam and pocketed coils, which lifts the sleeper up and out of the bed. This vibe should satisfy a wide range of sleepers, but I think it could be particularly well suited to combo sleepers who switch between their back and sides in the night.

Testing the Intellibed Matrix Grand

Though important, firmness is hardly the only factor to consider when buying a new mattress. So, I’m going to test the Intellibed for two more crucial characteristics: Pressure Relief 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 this gizmo out, hop aboard, and let the map do the rest! As I move around the structure, the gadget records the force my body’s exerting on the structure, and makes a colored “map” of the pressure. Blue indicates areas of low pressure and red indicates areas of high pressure.

Intellibed Matrix Grand Pressure
I was impressed with the pressure relief of the Intellibed Matrix Grand

Back – Lying on my back felt pretty comfortable! I could feel the top layers of foam filling in the space at my lumbar region for some nice pressure relief, but never felt stuck in the mattress. In fact, the bounce of the pocketed coils made it easy to move around and change positions.

Side – The comfort continued as I turned onto my side. Though I wouldn’t necessarily recommend this mattress for all-night side sleeping, it could be perfectly pleasant for folks who switch between their side and their back in the night.

Stomach – And finally, my stomach. While this bed is firm enough to support some light stomach sleeping, I’m not sure I’d recommend it for strict stomach sleepers. Why? Well, when I stretched out in this position, I could feel my hips sinking out of alignment with my shoulders, which is typically a big no-no for those who sleep in prone.

Motion Transfer

Next up, let’s talk motion transfer! This variable refers to the amount of movement detectable from one side of the mattress to the other, and could be a crucial factor for folks to consider if they share a bed with a child, partner, or 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.

These are pretty decent results, considering how bouncy the mattress is. I’d attribute this to the motion-dampening power of the all-foam pillow top layer, which works to dissipate movement across the structure. However, though small jostles will likely go undetected, larger ones may still cause some disturbance.

Should you buy the Intellibed Matrix Grand Mattress?

Well folks, we’ve arrived at the end of this review! After chatting construction, firmness, and feel, it’s time to answer the question you came here asking: Should you buy the Intellibed Matrix Grand? I can’t make that decision for you (sorry!), but I can leave you with a few final thoughts to help you get there on your own.

Intellibed Matrix Grand Recommendations

  • My favorite thing about this mattress is how supportive it is. If you’ve got aches and pains (and could do with a little neutral spine alignment), this could be a great mattress for you.
  • Specifically, I think it could be great for combo sleepers who switch between their back and side as they doze.
  • Thanks to the actively cooling Phase Change Material in the cover, it could also be a great pick for those who overheat in the night.

Intellibed Matrix Grand Complaints

  • At $9,000 for a Queen, the Intellibed Matrix Grand just isn’t going to be in everyone’s budget.
  • Additionally, I’d say it lacks contouring, so may not be the best fit for those in need of deep pressure relief in the shoulders, hips, or lower back.
