How Casper keeps prices low and quality high
When Casper was founded in 2014, many people were skeptical. Would consumers really buy a mattress without testing it first? Several years and numerous awards later, we have an answer: It turns out no one likes visiting stuffy mattress showrooms to make high-stakes purchases under the scrutiny of needy salespeople. (Who knew??)
Everyone loves the ease and convenience of buying online from a trusted source, and having a high-quality mattress shipped in a box to their doorstep for free. And people keep spreading the word that our mattresses deliver unparalleled comfort and support, top-notch construction quality, and high-tech, innovative design.
But the Casper experience isn’t just about quality, trust, and transparency. Our mattresses are a mere fraction of other brands’ prices. That’s because we’ve flipped the mattress industry on its head. By eliminating showrooms and middlemen, we keep our costs low - and pass those savings on directly to you.
Think cool. (No, cooler)
Propriety open-cell foam
Nothing will ruin a good night's sleep like waking up hot and sweaty. Our foam mattress enables airflow, so you stay comfortable and breezy through the night.
Relentless team of engineers
Our team of engineers and designers developed Casper mattresses with body temperature in mind, ensuring you have the most comfortable sleep possible.
Goodbye heat, hello sleep.
The foam is specially designed with up to 5 layers of premium foam (on our Wave) for an outrageously comfortable sleep.
Frequently Asked Questions
Standard twin bed mattress dimensions measure 38 inches wide and 75 inches long. The compact size of this single bed makes it an easy pick for children’s bedrooms, college dorm rooms, and other tight spaces.
Typically, twin mattress prices range from 400 CAD to 1750 CAD. The price depends on the quality and added features—materials, layering, cooling technology, and waterproofing all add up to a higher dollar amount. The mattress type can also affect the cost– whether it's a memory foam mattress, hybrid mattress, and so on.
The most important thing when looking at prices is to find the highest quality for that price point. Casper’s affordable Element twin mattress provides simple yet pleasing comfort, while the Wave Hybrid twin mattress adds memory foam and cooling gel layers for luxurious rest and the best support. Your twin bed in a box will quickly make for a stylish, sturdy, and space-saving bedtime experience.
A twin XL mattress is a comparable bed to a twin mattress but the main difference is that a twin XL has an added 5 inches of length and therefore measures 38 x 80 inches altogether. You’ll also find this type of twin size mattress in college dorms, as well as some apartment and condominium bedrooms.

By standard measurements, a full-size mattress, or double bed, is 53 inches wide and 75 inches long. This means that compared to a standard twin size bed —35 x 75 inches—a full mattress adds 15 inches of width to your sleeping space but no extra length.
For a single sleeper, a full bed’s extra wiggle room might provide a comfier rest or better fill out a larger bedroom. However, both sizes work for a solo sleeper.

A twin bed may feel too cramped for an adult to sleep comfortably in, therefore a different mattress size, like a twin xl or full may be better. However, it all depends on your sleeping needs and living space.
Historically, twin beds weren’t made for the average adult. They were sold in pairs for children’s rooms, hostels, and other co-living spaces. While twin beds work well for kids, they tend to be too small for grownups, especially larger individuals and restless sleepers.
For very small bedrooms, however, a twin bed may be necessary to save space. In that case, the least you can do to maximize your comfort is to upgrade to a Casper twin mattress in a box.
Most bunk beds are designed for twin mattresses, so the answer is usually yes— it makes for a great bunk bed mattress size! However, some bunk bed models accommodate a twin XL mattress (38 x 80 inches), and others have varied upper and lower bunks, usually with a twin on top and a double bed on the bottom. Before purchasing, make sure to double-check all bed frame dimensions.
