The OMG Mattress is not like other Mattresses 

All Mattresses are not created equal. 

Our objective in creating the OMG Mattress was to produce the finest online mattress we could, that would address sleep and health issues such as tossing and turning that cause sleep fragmentation; pain from sports or other injuries or arthritis in areas such as the shoulders, ribs, elbows, hips and knees that keep you awake; back pain; spinal support; sleep temperature (cooler is healthier); and a less than friendly damp sleep environment caused by body perspiration, while at the same time being medium firm (medium firm is better when it comes to sleep issues) and yet extremely comfortable to sleep on. All at an average Joe or Josephine affordable price. 

We don't like to brag, but we think we accomplished that with our 10.5” OMG Memory Foam Mattress. It's sleep re-imagined. A sleep game changer. Supercalifragilisticexpialidocious.

High Quality Fabrics

Here's what sets the OMG mattress apart from other online mattresses. It starts at the top. Our fabric is luxurious and anything but ordinary. Unlike almost all online mattresses that have 100% polyester stretch knit options, we have high quality fabrics.

We then channel-quilt our luxurious fabric to a 20 ounce layer of flame retardant, hypoallergenic, non-absorbent, moisture wicking, water, wrinkle and mildew resistant fibre. Because of cost, it's pretty uncommon to see a fibre layer in online mattresses. Along with the fibre we also add a layer of super soft gel foam. This foam layer adds a major dimension of comfort to the OMG.

NASA Memory Foam

Under the super soft foam layer, we get serious about helping you sleep not only comfortable, but better. We love science, and we love NASA. We took the world’s #1 pressure relieving foam, and created what we call proprietary OMG pressure relieving specialty memory foam.


It begins with traditional memory foam. Memory foam was invented in 1966 by Charles Yost under contract to NASA, as a cushioning material to relieve stress G-force astronauts were subjected to during spaceship takeoff. Once its great qualities were uncovered, it made its way into airline pilot and passenger seats, movie theatre seats, football helmets and shoes. In 1992 Tempur-Pedic® introduced memory foam into mattresses, as a solution to a better night’s sleep. If you’ve shopped for a Tempur-Pedic® mattress, you know they’re anything but cheap. Queen size mattresses range in price from $1,799 to $7,499.

Benefits of Traditional Memory Foam

Memory Foam has many benefits including:

  • Memory foam is known for relieving joint pain, pain from sport injuries or accidents, or arthritis pain, by taking pressure off pressure points such as shoulders, elbows, ribs, hips and knees.
  • Memory foam generally sleeps a bit firmer than regular foam. According to Dr. Jeffrey N. Katz (Professor of Medicine and Orthopedic Surgery at Harvard Medical School), and the National Sleep Foundation, a medium-firm mattress can lead to better sleep for those with back pain. 
  • As memory foam molds to the body in response to heat and pressure, it evenly distributes body weight without gaps like inner-springs, thereby improving blood circulation. The end result is reduced tossing and turning as you sleep, and less sleep interruptions if you're sleeping with a partner.
  • Memory foam cradles and gently contours to your body and lower back, and supports the lower back and spine as you sleep.
  • Consumers that sleep on mattresses containing memory foam, including those on a Tempur-Pedic®, give their mattresses the highest consumer rating (4 out of 5).


We’ve all experienced tossing and turning as we try to sleep in a hot environment. The benefits of sleeping in a cold room are varied, but all point to a better night's rest. When a room warms up, it tends to interrupt our sleep. Traditional memory foam tends to sleep hot, and as our bodies like it cool at night, we added both gel and graphite to the OMG.

Gel was originally introduced into memory foam by Serta® in their iComfort® line, to make for a cooler sleep. More recently graphite was introduced as a cooling agent in computers and other products. By adding both gel and graphitecomponents to the OMG Mattress you get double temperature regulation and cooling.

High Density Bio Foam

To further add to comfort, under the pressure relieving OMG specialty memory foam layers, we added a layer of High Density Bio foam made from soy based oils. In addition to providing comfort, this foam layer helps us reduce the carbon footprint in the OMG. Our final foam layer consists of 1.8 lb.

High Density Bio Support foam once again made from soy based oils. Anything less in Bed in a Box or one sided mattresses, and you’re going to compromise durability and mattress life. But we don’t stop there. We then finish the bottom with a no skid material, so that it doesn’t slide all over on whatever foundation you place it on. Last but not least, it’s made by Canadians, for Canadians. It's important to note that all our foams meet CertiPUR-US® standards for content, emissions, and durability.

That they've all been analyzed by independent, accredited testing laboratories.

  • No ozone depleters
  • No PBDEs, TDCPP, or TCEP ("Tris") flame retardants
  • No mercury, lead, and other heavy metals
  • No formaldehyde
  • No phthalates regulated by the Consumer Product Safety Commission
  • Low VOC (Volatile Organic Compound) emissions for indoor air quality (less than 0.5 parts per million)

Cooling Mattress Protector

We also have an additional cooling option available for those that want an even cooler sleep. Our Khao mattress protector can reduce sleep temperature by 2 to 3 degrees. It's infused with Silver Ion agents, that when oxidized can effectively kill bacteria.

Sleep with the Stars

In summary, we believe our OMG is the best in class mattress available online today in its price range. One that incorporates fibre for temperature regulation and moisture wicking. One that contains our special proprietary OMG pressure relieving memory foam with gel and graphite to reduce sleep temperature and tossing and turning and back pain issues. One that relieves joint pain, pain from sport injuries, accidents, and/or arthritic pain, by taking pressure off pressure points such as your shoulders, elbows, ribs, hips and knees. One that provides spinal support. And last but not least, one that’s firm enough yet so comfortable you’ll wake up rested, restored and rejuvenated, and wanting to stay in bed longer. Nothing compares to our OMG 10.5 Inch pressure relieving, cooling mattress. As soon as you lie down you'll be saying "Oh my God!"

101 Night Trial

We’d like to make you the following offer. Like most of our online competitors we offer a free trial period. In keeping with everyone else we offer 101 nights, although we don’t believe anyone needs 101 nights to determine whether or not a mattress is blow away. We do agree with an adjustment period, but if your new mattress is not providing a good night’s sleep after 30 days, it probably never will.

If our OMG isn’t supercalifragilisticexpialidocious after 30 nights please contact us to make arrangements for you refund.

Take a Video, Get $50

On the other hand, if you love your OMG send us a video praising its virtues. Kiss it! Hug it! You name it! On receipt of your video and permission to use it online, we’ll send you $50, and a $50 gift certificate towards another OMG for either yourself or a friend.

The OMG Referral Program

And if you keep referring friends we’ll keep send you $50 every time they buy an OMG (see referral conditions).


Mattress Sizes & Dimensions and Bed Size Guide | Gotta Sleep

Mattress Sizes and Dimensions

Looking for mattress sizes?  This article will help you find the right dimensions for your mattress.  Beds come in many sizes, from the small single Twin to the massive California King.  Unfortunately, manufacturing procedures, padding and types of support can all alter the size.

IMPORTANT: This guide offers the most common sizes.  It is important to know that there is no legal standard mattress dimensions.  As a result, if you are looking for a specific bed size in Canada or the USA, be sure to ask your vendor for exact measurements if you are unclear.   

In Canada and the USA, we use terms like Queen, King, Double and so on to define mattress sizes. 

The commonly manufactured sizes in Canada and the USA are:

Bed sizes in Canada are typically the same as US bed sizes.

Standard Mattress Sizes Differ Based on Type

For each mattress and box spring, there are actually TWO acceptable sizes:

When the coils in spring or coil mattresses are manufactured, the count and thickness of the wire varies. This can greatly affect the width and length of coil mattresses. Because of this in Canada and the USA, manufacturers must produce inner-spring or coil mattresses within 1” of what they have indicated in their marketing.

Foam mattresses are cut from slabs of foam, so their sizes don't vary as much.  As a result, you don’t have to worry about size variations with foam mattresses. They are the exact size they state on the label and description.  

When buying mattresses online, like bed in a box, they’re usually foam mattresses. Some of them also contain coil inner-springs, so it’s good to check.

Mattress Sizes Explained

Twin or Single - 38" x 74½"

Despite ‘Twin’ being in the name, twin sized mattresses are mostly used for single sleepers. The average length of single bed is 74 1/2.  The average width of single bed is 38".  Their small size means they’ll fit well in most spaces. It’s a great size for growing kids to give them enough space to sleep and grow without taking up so much space. It’s also the most common size found in dorms due to their compact but comfortable size.

Depth dimensions vary.

Twin XL - 38" x 79½"

Twin XL bed dimensions measure 38" x 79½".  The average length of Twin XL bed is 79 1/2".  The average width of Twin XL bed is 38".  

Like a twin, this mattress is the same width, but is 5 inches longer to accommodate taller sleepers. This size is commonly used for growing teenagers who are close to 6’0” and in dorm rooms.

It’s a longer economy size that’ll fit well in the spare room.

Super Single - 47" x 74½"

Super Single bed dimensions measure 47" x 74½".  The average width of a single bed is typically 47".  The average length of a single bed is 74 1/2".  

Super Single beds are a throwback to the 1920s.  Designed for one sleeper but often accommodating two, these beds are very rare on the market today. For the most part, only antique bed frames and military living quarters will require this size so Gotta Sleep doesn’t carry it.

Double / Full - 53" x 74½" to  75"

Double or full bed dimensions typically measure 53" x 74½".  The average length of a double bed can extend to 75" which is why the 53 x 75 size is also quite common.  The average width of a double bed is almost always 53".

The double, or the full, used to be the industry standard for a bed meant for two people. It wasn’t until the 1950s that the Queen sized mattress overtook the market, as people were getting taller and rooms were getting larger.  Couples appreciated the extra space offered in a Queen.

It’s a popular choice nowadays for spare bedrooms, luxurious singles, growing children, or spaces that aren’t quite large enough for a queen. 

Full mattresses work great for children as they are cost-effective and are long enough to last until the child has grown into an adult.

Double XL or Full XL - 54" x 79½"

The Double XL or Full XL comes in at 54" x 79 1/2".  The average length of Double XL bed is 79 1/2".  The average width of Double XL bed is 54".

The full extra long can be found as a 53 x 80 mattress.  Just like the Twin XL, the Double or Full XL is made longer and a little bit wider. It’s meant to accommodate the taller sleepers or those who want something just a bit bigger than a double, but don’t have excess of space. Unfortunately, this less popular option is not carried at Gotta Sleep.

Queen - 60" x 79½"

Queen-sized mattresses range between 55 and 100 pounds and the average dimensions of a queen size bed typically are 60" x 79½".  The average length of Queen bed is 79 1/2".  The average width of Queen bed is 60".

Queen sized mattresses have become the preferred and most popular size on the market. It’s considered the ideal size for two people to share, and fits comfortably into most modern bedrooms.

They provide plenty of space for sleeping, even for those who move a lot in their sleep. Gotta Sleep offers high-quality Queen-sized memory foam mattressesthat greatly reduces motion transfer. This makes it even more desirable for couples, as getting up or rolling over won’t disrupt the other person’s sleep.

Because Queen mattresses have more room, restless sleepers can sleep the night without being woken by the people next to them as they turn in their sleep.

It’s considered the most cost effective mattress, meaning it’s the most mattress for the least expense. There’s benefits to buying the most popular mattress out there.

Queen RV - 60" x 74½"

A Queen RV bed dimensions measure 60" x 74 ½".  The average length of Queen RV bed is 74 1/2".  The average width of Queen RV bed is 60".

Essentially a Queen mattress but 5 inches shorter, the Queen RV is exactly what it sounds like. They’re made for Fifth Wheel, Travel Trailers, and Motor homes, where every bit of space matters.

It’s rarely found outside of these contexts, as the name would imply it was a size invented with nothing but RVs in mind. As a result, Gotta Sleep does not carry this size. If you find yourself in need, give us a shout.  We would be more than happy to help you.

King - 76" x 79½"

King bed dimensions measure 76" x 79½".  The average length of King bed is 79 1/2".  The average width of King bed is 76". 

At double the width of a twin, the King sized mattress offers 16 inches more wiggle room than the Queen. Even the most restless sleepers won’t disturb their partners on this massive surface. Not recommended for smaller rooms unless taking up the entire floor-space with a mattress is your idea of a perfect bedroom.

For those who often have children or pets joining them to sleep, the King sized mattress is large enough to accommodate everyone without feeling cramped. It’s highly recommended for families who have the space. We often hear couples say that once they got a King sized mattress, they couldn’t comfortably go back to a smaller size. 

If you are interested king bed dimensions Canada, you don't have to worry they are the same as the US.

If you have a small bedroom, we would not recommend this large-sized mattress, but for medium to larger rooms, this is often the most comfortable choice for couples who like to spread out in their sleep.

California King - 72" x 83½"

California King bed dimensions measure 72" x 83½".  The average length of the California King bed is 83 1/2".  The average width of the California King bed is 72", 4 inches less than a King bed.

If you are looking for a mattress that can truly accommodate taller people, those who like to stretch out in their sleep or share their sleeping spaces with pets or children, nothing will beat a California King mattress.  

A little bit narrower and a hand longer, California Kings are the kings of comfort. It’s ideal for taller people who like the extra foot room, as well as those who have pets that like to sleep on the end of the bed. The extra length lowers the risk of getting kicked off in the middle of the night.

The California King’s luxurious size means you might not have the space for end tables or dressers in some bedrooms. For those with the space, the sprawling space may be worth it.

Other Considerations

When deciding on which size mattress is right for you it is important to consider a variety of influential factors. Each of these factors play a significant role in sleep quality, comfort and can help to select the perfect mattress. By carefully selecting the bed dimensions or size of mattress you are one step closer to ensuring you can receive a proper night's sleep.

Country of Origin

Mattress sizes vary from country to country. Standard sizes in Canada and the USA are mostly the same, but there are some slight variations. Common bed sizes for the U.K. and E.U. are listed below, they don't all quite match up the same way.

Popular U.K. Bed Sizes

Grand King 71 in x 79 in 180 cm x 200 cm
King 60 in x 78 in 152 cm x 198 cm
Double 53 in x 75 in 135 cm x 190 cm
Single 35.5 in x 75 in 90 cm x 190 cm

Popular European Bed Sizes:

Grand King 71 in x 79 in 180 cm x 200 cm
King  63 in x 79 in 160 cm x 200 cm
Double 55 in x 79 in 140 cm x 200 cm
Single 35.5 in x 79 in 90 cm x 200 cm

If you’re not sure about the right mattress type your bed frame, and our sizing charts are a touch too confusing, you can reach out to us for clarification. Things like manufacturing procedures, padding, and types of support can all alter both the length and width of a bed. These things can vary country to country, so it’s good to check.


Your height can play a large role in determining the perfect mattress size, especially if you are taller than average. XL or California King mattresses can be ideal as since they provide more length to accommodate longer legs.

When you are unable to comfortably fit your entire body on your mattress, you are potentially compromising your quality of sleep. With the wide variety of dimensions available, no one should have to sacrifice comfort as a result of their above average height.

Room Size

The size of the bedroom or space where you would like to place the mattress is another factor to consider when choosing the perfect mattress. A mattress too small or too large can offset the feel of the bedroom and leave it feeling either empty or overloaded. If space is limited a smaller mattress is always recommended. Before making a purchase, it’s important to measure the room to figure out how much space you have to work with. You want to make sure the room has enough space to safely navigate through, and enough space for other furniture like an end table and/or dresser. Of course, if the room can accommodate a larger mattress, having more space can result in a more comfortable sleep.

Measure the Space

Before your purchase a mattress, take the time to measure the space or the bedroom that the bed will go into. This will give you an accurate idea of the size of mattress you should buy. The last thing you want is to have a mattress delivered to your house that does not fit the bedroom.

Number of Sleepers

For individual sleepers a Twin or Double size mattress will provide good amount of room to ensure a quality sleep. If you share a mattress the bigger you can afford the better. For two people a Queen or King-sized mattresses are ideal. If you’re lacking space, a double-sized mattress is the next best option.

When sharing a mattress with two adults and children or pets a King or California King sized mattress is best. These large mattresses will provide space for two or more individuals to sleep comfortably, but putting one in a too-small bedroom can be a safety hazard and make the room feel cramped and uncomfortable.

It’s important to be thorough when deciding which mattress is right for you. By choosing carefully you’re guaranteed a good quality and restful sleep. Remember that standard mattresses sizes Canada and standard mattress sizes USA, do not include bed linens.

Custom Sizes

There are some bed frames and furniture that require non-standard sized mattresses, such as the 3/4 size and other antique sizes. If you need a mattress with custom dimensions, Gotta Sleep has options outside of the standard sizes we sell to solve any and all of your sleeping needs. Whether you are looking for a specific rv mattress size for your Recreational Vehicle (RV), truck, unusual room, or boat, we can custom order mattresses in specific sizes to meet your needs.
