In other words, the kind of sleep you have the night before can determine the kind of day you’ll have after. That is where the company, Hyphen, comes in.

Hyphen Sleep is a sub-brand of the mattress company, Diamond Mattress, which has been around for more than seven decades. With such an established background, Hyphen assures its customers that they get the sleep that they deserve.

Let’s’ start with the basics:

Design & Construction

The Hyphen Sleep mattress is a bed in a box mattress, which simply means what it implies – that it will come inside a box when it’s shipped to your house. 

Overall, the mattress consists of three layers and, of course, the cover.

We’ll discuss the cover and each layer in detail:

First Layer

The top layer is the mattress’ comfort layer. It’s a 2-inch foam designed by Hyphen themselves. The foam is soft and quickly responds to pressure unlike most memory foam mattresses. On top of that, with the fast responding foam, you won’t get that “stuck” feeling when sleeping in one position.

This layer also comes with a unique design – hole punches, which serves as airways where air can properly flow, providing maximum breathability. Plus, the copper-infused mattress makes sure to absorb the heat, keeping your body cool throughout the night.

Second Layer

This is the transitional layer, composed of a 2-inch polyfoam material. It serves as a seamless shift from soft to firm that adds to the overall experience. This layer was designed to be buoyant so that it’ll be easier for sleepers to change sleeping positions.

Third Layer

Lastly, we have the base layer, which is made of a 6-inch polyfoam. The high-density foam provides firm support for the sleeper, which is not new in the memory foam industry. Although this mattress does an excellent job at equalizing pressure and is also highly durable.


The Hyphen’s cover is a combination of spandex and polyester, providing a silky and elastic feel to it. The elasticity helps keep the cover in shape without showing bulges with every movement. Also, the cover is antimicrobial, hypoallergenic, and highly breathable, promoting healthier sleep, indeed. 

The Hyphen Sleep mattress goes with any bed frames, surfaces, and even adjustable bases available, given that they are solid in construction.

Overall, the mattress is 10 inches in height, it is not the tallest mattress in the market as of now. 

However, it does a better job than most memory foam mattresses. Although that will be up to you, which is what we will be talking about next.

Who Is The Hyphen Mattress For?

Of course, there are some people who could benefit a lot from sleeping on the Hyphen Mattress and some that don’t. 

For now, let us show you those who would love sleeping on its surface.

People Who Want To Sleep Healthier

With the cover of the mattress being antimicrobial and hypoallergenic, the mattress eliminates health hazards from invading your body while you’re resting. Hyphen knows that sleep should be a peaceful and care-free space for everyone. With the Hyphen Mattress, you won’t be worried about waking up sick anymore.

People Who Want To Sleep Cooler

The Hyphen Mattress is designed for people who sleep with warmer body temperatures. The infused copper on the comfort layer excels at removing heat from hot sleepers, regulating body temperature for optimal sleep. With the added hole-punches, proper ventilation can be achieved. Hyphen clearly outdid themselves on this design feature.

People Who Sleep On Their Backs, Sides, and Stomachs

With the mattress equal balance of softness and firmness, it provides support for all sleeping positions. The overall construction of the three layers creates fantastic and vital assistance to the body’s natural posture.

The people who prefer sleeping on their backs, the mattress provides much-needed pressure relief from the lower back, which is a critical area for back sleepers, diminishing the chances of experiencing lower back pain and aches in the near future all-together.

The mattress’ soft feature means it’s wonderful for side sleepers. Although sleeping on their sides brings more pressure, the mattress does a superb job of equalizing this, providing relief for side sleepers.

People of average size and weight who prefer to sleep on their backs would also love sleeping on the Hyphen Mattress. Although back sleepers need more firm mattresses than Hyphen, the bed’s buoyant property keeps the hips from sinking too much, keeping the spinal alignment in check. However, as stated earlier, this only goes for average sized sleepers.

Who Is The Hyphen Mattress Not For?

Now let’s discuss those who would find the Hyphen Mattress unappealing or those who cannot take advantage of the mattress’ features. 

Do you think the bed is not for you? See why.

People Who Want More Firmness Selections

Unfortunately, the mattress only comes with a medium-firm feel. Although the Hyphen Mattress offers a unique pressure relief design, some might want a softer mattress, and some might want a firmer one. Once the mattress is concerned, you’re only stuck with a medium-firm option.

People Who Want An Innerspring Mattress

The Hyphen Mattress is designed for people who sleep with warmer body temperatures. The infused copper on the comfort layer excels at removing heat from hot sleepers, regulating body temperature for optimal sleep. With the added hole-punches, proper ventilation can be achieved. Hyphen clearly outdid themselves on this design feature.

Firmness Check

On a firmness scale of one to ten, with one being as soft as a cloud and ten being as hard as a brick, the Hyphen Mattress falls in the middle, landing on a 5.5 out of ten. That is essentially wonderful for most people.

One of the first things that you will notice once lying down on the mattress is how fast the foam responds to your body. The mattress quickly embraces you while also providing plenty of support on areas that apply a lot of pressure. 

The next thing you’ll notice is how easy it is to toss and turn. With the Hyphen Mattress, you won’t have to worry of getting stuck and uncomfortable. The latex-like performance of Hyphen’s materials provides excellent bounce for users.

Overall, with the Hyphen Mattress scoring a 5.5, it provides an equal balance between comfort and support that should be fantastic for average-sized people.

Motion Transfer Check

If you’re sleeping with your partner, child, or pet, and you find that you frequently toss and turn during sleep or get up from bed, the Hyphen Mattress is suitable for you and whoever you share your bed with. They will thank you for not disturbing them while they sleep, especially if they are all light sleepers. You can rest assured that as you roll around in your sleep, the other person on the other side won’t feel a thing with the Hyphen Mattress due to its excellent motion transfer features.

Edge Support Check

Again, if you are sharing the bed with your partner, edge support is vital. However, the Hyphen Mattress does an excellent job in this section as well. Once you lay down on one side, you will feel your weight equally distributed as if to feel you’re not sleeping on the edge at all, and with its proper edge support, you can be sure that you won’t fall as easily off the bed as you might think.

One thing to take note, however, is whenever you’re sitting on the side of the mattress, you will feel a lot more compression and sink a bit more. This is because all of your weight is focused on one area only. Although that is not uncommon for foam mattresses, either.

With the Hyphen Mattress providing extraordinary edge support, it may come as a surprise to some. That is because memory foam mattresses don’t necessarily perform well when it comes to edge support.

More Crucial Information

Now that we’ve finished talking about the Hyphen Mattress’ design, construction, edge support, movement transfer, and others, let’s now get down to the specifics. If you’ve stuck around until now, chances are, you want to get a Hyphen Mattress for yourself or for someone you know as a gift, but you need to know about its more important details. So, let’s get you started on the mattress’ specifics.

Sizes And Prices

The Hyphen Mattress offers six sizes and the prices are dependent on each size.

Twin 38” x 74” x 10” $575
Twin XL 38” x 90” x 10” $675
Full 53” x 74” x 10” $800
Queen 60” x 80” x 10” $950
King 76” x 80” x 10” $1,095
California King 72” x 84” x 10” $1,095

Overall, the Hyphen Mattress produces quality mattresses at a much lower price compared to other bed-in-a-box mattresses that provide the “same” features.

Warranty Policy

Hyphen offers a 20-year limited warranty for all its products, and this warranty is separated into two terms:

  • First Ten Years – During this time, if the user should find any defect or whatsoever, Hyphen will either repair or replace the mattress free of charge.
  • Last Ten Years – If the user finds any damage or defect, the customer shall be paying $99 in order for Hyphen to repair or replace the mattress.

Here are the possible defects that the warranty cover:

  1. Broken or damaged zippers, and/or any defect or damage relating to the cover of the mattress.
  2. The fast decline of the mattress quality, leaving significant depression marks that are more than an inch in depth.
  3. Any defects or damage from a mattress that wasn’t bought from Hyphen or from an authorized dealer. The warranty does not cover any mattresses bought “second-hand”.

Here are the possible defects that the warranty does not cover:

  1. Cuts, burns, stains, or any defect or damage caused by the improper use, handling, or cleaning of the mattress.
  2. The increase of softness of the foam material, which is, in fact, highly common in memory foam mattresses.
  3. The change of the user’s preferences regarding the level of comfort and fairness. Hyphen will not replace or repair such a mattress if that is the case.

Your warranty will be voided once the foundation of the mattress is not the product recommended. Hyphen states that their mattress’ foundation should have an adjustable base, or the foundation should have a bed frame that sufficiently carries all the weight involved.

Any customer who purchases a Hyphen Mattress on an online platform receives the same warranty policy as those who bought it from the Hyphen Website.

When replacing a defective mattress, the customer may opt for a much higher unit, however they would need to pay the difference between the two products. Additionally, if a customer decides to replace their mattress with an upgraded one, they will be given a new warranty period that starts when their upgraded unit arrives.


The Hyphen provides free shipping and returns anywhere in the US. Although, Hawaii and Alaska would need to pay a return fee when doing so.

Trial Period

Hyphen offers a 100 night sleep trial for all its mattresses for the customers to get a better feel of the bed.

CertiPUR-US® Certified

This ensures the user that no harmful chemicals, substances, or materials were used in the making of the Hyphen Mattress.
