Complete INTELLIbed Legacy Collection Mattress Review

Founded in 2000, the INTELLIbed company stakes their claim to fame on their unique ‘INETLLIgel’ technology known as Gel Matrix.

Unlike traditional memory foam or pocket coils, this special gel material molds closely to the body to provide intelligent pressure point support.

More specifically, the Gel Matrix layer is formed into ‘a grid of hollow columns (similar to a flexible ice cube tray.)’ 

According to the manufacturer, these columns ‘progressively buckle under increasing pressure’ and ‘respond to every part of your body.’

There are three products in the INETLLIbed Legacy Collection: The Azure, the Sapphire, and the Indigo.

What Type of Mattress is the INTELLIbed Legacy Collection?

This is where things get complicated. The mattresses in the INTELLIbed Legacy collection aren’t coil mattresses, they aren’t foam mattresses, they aren’t even gel mattress. 

They are a hybrid of all three. 

That’s right, the Azure, the Sapphire, and the Indigo feature the best of all of the popular sleep technologies.

To quote the manufacturer, “The Firm and Soft Gel Matrix is supported with a high coil count connected innerspring to provide the best back support possible. Centipur Foam is used beneath the Gel Matrix to provide extra cushioning.” 

How Firm is the Mattress? Will I get a Good Nights Sleep?

Interestingly, reviewers report INTELLIbed mattresses as being both soft and firm, citing them as feeling firm at first but quickly molding to the body to provide almost instant pressure relief.

Each one of the mattresses in the collection is recognized for their ability to offer support for all sleep positions.

We like how quickly the bed responds to pressure, helping to prevent the feeling like you are sinking into the bed that is typically experienced with conventional foam mattresses.

Another feature that we appreciated about the mattresses in the Legacy collection was how each differed in firmness level slightly, therefore, making it easier to custom select firmness levels. 

How does each bed measure up on the 1 to 10 firmness scale?

  • The Azure rates 6.5 out of 10, making it a ‘medium firm’ bed.
  • The Sapphire rates a 5.5 out of 10, making it ‘medium’ bed.
  • The Indigo rates a 4.5 out of 10, making it a medium-soft’ bed.

What About Motion Transfer? Will I Wake my Partner if I Roll Over?

Keeping in mind that the beds in the Legacy collection do have inner coil systems, we weren’t surprised to read that there was much more ‘bounce’ than in regular foam beds. 

That being said, the number of reviewers who mentioned moderate to high rates of motion transfer were far fewer than we had expected. 

If you sleep next to someone who moves around a lot, you might notice some movement, but they would really have to be putting some force into it for the movement to be noticeable enough to disturb your sleep. 

This is one mattress collection where you can really feel comfortable if you want to ‘get down and move it all around‘ without worry. Seriously, it’s that good at absorbing motion – and noise!

How are the Layers of the INTELLIbed Legacy Collection?

As previously mentioned, there are three mattresses in the Legacy collection. We will discuss each of them individually, starting with the Azure. 

The Azure has four layers;

The Top Layer (Premium Quiltfex & Silica fire-blocker) makes the bed fire resistant and also helps to regulate temperature. 

Next, the Gel Matrix Layer (Non-toxic, hypoallergenic, zero off-gassing, sleeps cools, 20-year durability) promotes airflow through the layers and creates pressure relief. 

Third, the CertiPUR layer (high-density foam) not only makes the bed more durable but also helps to keep the mattress free from permanent imprints or impressions.

And finally, the Support Layer ( laced inner-spring, high-quality steel, superior durability) increases stability and improves alignment. 

The Sapphire boasts the same basic layers as the Azure, however, the sleep surface has wrapped pocket coils to help to alleviate some of the motion transfer complaints from the Azure. 

Lastly, the crème-de-la-crème of the collection, the Indigo has two impressive layers of Gel Matrix and a premium quality cover. 

Below that, multiple Talalay Latex foam layers and a layer of Serene help to all but eradicate any threat of motion transfer and 5 coil zones to provide maximum support and alignment.

You will notice that each of the mattresses in the Legacy collection use Silica fire-blocker in their construction.

While we don’t necessarily recommend testing the capability of the bed to withstand actual fire, it’s okay if you and your partner want to try to make a few ‘sparks.’ In fact, we encourage it!

Does it Come with a Mattress Cover?

We were a little bit taken put off by the fact that even though each of the mattresses in the Legacy collection come with a quilted mattress cover – a separated mattress protector was required in order to take advantage of the trial period and to honor the terms of the warranty.

The manufacturer recommends purchasing one from Malouf, for an added fee of $51.99 to $83.99, depending on the size of the bed. 

The Malouf Prime Terry Mattress Protector is considered a ‘non-returnable item’. It is marketed as being hypoallergenic, and:

  • Protects the top of the mattress from spills and stains
  • Repels allergens and dust mites
  • H2Pro Liquid Proof Membrane 
  • Universal elastic fit for various mattress depths

Does the Mattress Sleep Hot?

After looking into the Azure, the Sapphire and the Indigo, we were unable to find any reviews or feedback that might indicate any sort of temperature regulation issues.

Each of the mattresses in the INTELLibed Legacy collection has an inner coil system and not an actual foam core. Foam is known to retain heat, a coil system allows for more air flow and better heat dissipation.

If you are someone who regularly sleeps hot, the manufacturer promotes a line of bamboo sheets that help to wick moisture away from the body and prevent the build-up of heat under the sheets. 

What About Off-Gassing? Does the Mattress Smell?

One of the qualities that the folks behind INTELLIbed really take pride in is their commitment to non-toxic materials in their products. 

None of the common toxic chemicals (like boric acid, petrochemicals, polyurethane, formaldehyde, and phthalates) are used in the construction of their mattresses.

Because of this commitment to quality and safety, there is absolutely no off-gassing or mattress toxicity.

If any unusual smells or off-putting odors are noticed, they are more likely to have come from the shipping materials rather than the bed itself. 

The easiest way to get rid of these smells is to crack a window and wait it out. However, if you aren’t able to wait for the 2 to 3 days it might take for the smell to clear out, you could always reach for your favorite fabric freshener spray.

To further expand on the chemical-free properties of the mattress, you could try making your own non-toxic mattress spray. To do so, combine the following into a clean spray bottle:

  • 1 cup of cooled boiled water
  • 1 cup of vinegar
  • 8 drops of eucalyptus essential oil
  • 8 drops of lavender essential oil
  • 8 drops of peppermint essential oil

Shake the bottle vigorously to combine the ingredients. Spray lightly onto the mattress and allow to dry – you might want to patch test first to test for potential discoloration.  

How Long will the Mattress Last?

The Gel Matrix used in the development of all INTELLIbed’s is extremely durable. The manufacturer states that it should never melt or crumble. 

Every single INTELLIbed mattress that comes without an adjustable base (this includes the Azure, Sapphire, and Indigo) has an anticipated lifespan of 20 years. 

Having said that, the lifespan and ‘period of usefulness’ seldom go hand in hand. Our research and experience tell us that mattresses (regardless of construction) often surpass their period of usefulness at around the 8- to 10-year mark.

In fact, even the INTELLIbed website recommends changing your mattress every 8 years.

But, if you do intend on keeping your bed for more than two decades, it is backed by 20-year ‘no sag’ warranty.

How Should I Care for the INTELLIbed Legacy Collection?

The only thing that the manufacturer recommends for caring for any of the beds in this collection is the additional purchase of the mattress protector. 

Outside of that, the typical rules apply, spot clean as necessary and maybe avoid things like eating a bowl of spaghetti and tomato sauce or wearing your muddy work boots to bed. 

We’ve put together a handy guide to help you care for your new mattress and keep it smelling fresh. Check it out here: Mattress Care Guide.

Where is the Mattress Made?

Advanced Comfort Technologies, Inc. – the company behind INTELLIbed –  pride themselves as being a homegrown, salt of the earth type of company.

They were born from humble roots in Salt Lake City, Utah and nearly two decades later they still design and manufacture each of their beds and accessories in the very place they first started. 

How Big is the Bed? Will it Fit in My Room?

The Azure bed is 12″ thick and comes in the standard sizes, ranging from Twin to California King.

Measurements include:

  • Twin: 39″ x 75″
  • Twin XL: 39″ x 80″
  • Full: 54″ x 75″
  • Queen: 60″ x 80″
  • King: 76″ x 80″
  • California King: 72″ x 84″

The Sapphire bed is 13″ thick and comes in the standard sizes, ranging from Twin to California King.

Measurements include:

  • Twin: 39″ x 75″
  • Twin XL: 39″ x 80″
  • Full: 54″ x 75″
  • Queen: 60″ x 80″
  • King: 76″ x 80″
  • California King: 72″ x 84″

The Indigo bed is 15″ thick and comes in the standard sizes, ranging from Twin to California King.

Measurements include:

  • Twin: 39″ x 75″
  • Twin XL: 39″ x 80″
  • Full: 54″ x 75″
  • Queen: 60″ x 80″
  • King: 76″ x 80″
  • California King: 72″ x 84″

What is really unique is that, in the Azure, Sapphire, and Indigo, both the King and California King sized mattresses are available in ‘split’ versions – Meaning that the bed comes in two halves (instead of as a whole unit) for easy portability and shipping. 

Do I Need a Foundation or a Bedframe?

If you are purchasing the mattress as a single unit (ie. not one of the ‘split’ versions) you don’t necessarily need to purchase a foundation or a bed frame as doing so is really a matter of personal preference, rather than effectiveness.

If you do decide to use the bed with a foundation or a frame, it is important to use one that has a solid center to support the weight of the box spring and mattress – slats are not recommended and might void the warranty.

Anyone interested in using the bed with an adjustable base should be cautioned that the manufacturer has laid out different warranty terms for these types of situations. In fact, some sources have mentioned that using an adjustable base reduces the warranty terms by as much as 10 years.


This is where things get complicated, there was a lot of conflicting information on the Internet about the warranty terms and options offered to INTELLIbed customers. 

We weren’t able to easily find a navigational link to the warranty page directly from the website, in clicking on the ‘live chat’ option, we noted wait times of 5+ minutes before being connected to a company representative. 

Our question was simple, “Is there a link to your warranty information that we can review for the beds in the Legacy collection?” We were provided with a link, and no other information – not even a prompt to ask if we were satisfied or had any other questions, the agent simply disconnected. 

We knew from earlier research that customers were required to purchase a specific mattress protector in order to meet the terms of the trial period and/or the warranty. 

But, we were surprised to learn that the company requires you to keep the bed for a period of no less than 30-days before being eligible for no-cost refund or return under the 90-day trial period. (Note – under the return section, the manufacturer actually states the in-home trial time as being 60-days)

If you decide to return the bed within the first 30-days, you will be required to cover all of the shipping costs.

While we are on the topic of shipping, it should be mentioned that shipping is not free – In fact, that cost of shipping in the United States ranges from $269 to $369.

How Much Does the Bed Cost?

If you are on a tight budget or are expecting perks like free shipping, or free removal of your old mattress, this may not be the mattress company for you.

Should you decide to purchase one of the beds in the Legacy collection direct from the website today, you would pay:

Azure cost (plus relevant shipping and mattress protector fees)

  • Twin: $2699
  • Twin XL: $2699
  • Full: $3499
  • Queen: $3799
  • King: $4499
  • California King: $4499
  • King Split: $5398
  • California King Split: $5398

Sapphire cost (plus relevant shipping and mattress protector fees)

  • Twin: $2999
  • Twin XL: $2999
  • Full: $3799
  • Queen: $4199
  • King: $4999
  • California King: $4999
  • King Split: $5998
  • California King Split: $5998

Indigo cost (plus relevant shipping and mattress protector fees)

  • Twin: $3799
  • Twin XL: $3799
  • Full: $3499
  • Queen: $5499
  • King: $6399
  • California King: $6399
  • King Split: $7598
  • California King Split: $7598

INTELLIbed Legacy Collections Mattress Review – Our Verdict

The care and quality that goes into making the Azure, Sapphire, and Indigo is impressive. We were particularly drawn to the ability to customize firmness, and how easily each mattress responded to body pressure to support limbs and tired muscles.

But, with a starting cost of $2699 for a twin, ranging all the way up to $7598 for a California King (and the added costs of shipping and the purchase of the required mattress protector) we are left with a bit of a sour taste in our mouths. 

With an upper-end cost of what most people might expect to pay over the course of an entire year for their first apartment, we expected more ‘frills’ or at the very least – free shipping. 

We were also slightly concerned by the amount of conflicting information found on the company website and how difficult it was to find any warranty details.

All in, these are high-quality beds – you are pretty much guaranteed a great nights sleep and premium pressure-relief and muscle support – but the superiority of the bed is overshadowed by the substantial cost and lack of customer support.
