Choosing a Mattress Size
King
When it comes to the master bedroom, most people want a spacious mattress that can accommodate two adults and the occasional child or pet. Measuring an expansive 202 cm x 193 cm, a king is the widest mattress size available, providing enough room for two adults to stretch out in luxurious comfort.
Queen
The most popular mattress size on the market, a queen mattress provides ample room for two people to sleep comfortably, without sacrificing valuable space in the bedroom. Measuring a comfortable 202 cm × 152.5 cm, this versatile sized mattress is a wonderful option for both guest bedrooms and smaller sized master bedrooms.
Double
The size of a double mattress is great for single sleepers who want extra space, and for couples who love a cozy night's sleep. Measuring a modest 189.2 cm x 134.6 cm, the double mattress works well for teenagers who like to stretch out, small bedrooms, or guest rooms that serve as an office or playroom when not occupied.
Twin
The space-saving twin mattress is the perfect solution for small bedrooms, bunk beds, dorms, or vacation homes. Measuring a narrow 189 cm × 96.5 cm, the twin is the smallest mattress size available, and intended for use by single sleepers. Its small scale ensures that it will take up very little space, and allows for lots of flexibility in placement. And in the case of a shared bedroom, each person can still have their own bed without the room feeling too cramped.
Twin XL
If you'd prefer a little more length than the standard twin mattress provides, then try a twin XL mattress. Measuring 202 cm x 96.5 cm, this slightly longer version of the twin is a more comfortable option for adults, as well as taller kids who need a little extra leg room. And because it's the same length as a queen mattress, it can be used well into the teenage years.
Best Mattress for Each Sleeping Position
Sleeping on the wrong mattress will not only leave you restless, it can also cause muscle strain and misalignment of your neck, back, and hips. That's why it's crucial that you have a mattress that complements your preferred sleeping position. So, whether you sleep on your back, on your side, or flat on your stomach, we've got a few tips to help you find the mattress that best suits your needs.

Selecting the Perfect Mattress Type
Innerspring Mattresses
Affordable and long-lasting, traditional innerspring mattresses are still the most popular mattress on the market. These sturdy mattresses feature a core of steel coils and springs wrapped in a soft outer layer of padding and fabric. Due to their strong construction, innerspring mattresses are very supportive and maintain their shape well over time. And because their coil base allows for easy air circulation, innerspring mattresses are breezy and low-temp, making them a great choice for stomach sleepers, and people who tend to overheat during the night.
It’s important to note that innerspring mattresses are more reactive than other types of mattresses, so you will definitely experience more movement and sound. And depending on the type of bed frame being used, an innerspring mattress may require the purchase of an additional box spring.
Hybrid Mattresses
The hybrid mattress combines the durable coil springs of a traditional innerspring mattress with multiple layers of cushioning memory foam, for the perfect balance of comfort and support. This unique design provides great air circulation as well as valuable pressure point relief, so it’s a suitable choice for all sleeping positions. Best of all, these mattresses are available in numerous firmness levels, so you can really customize your sleep experience.
Hybrid mattresses come in a variety of price points, but they do tend to be expensive. Due to their coil spring base, there will be some bounce and noticeable motion transfer. Hybrid mattresses are also heavy, making them somewhat difficult to move.
Memory Foam Mattresses
Memory foam mattresses are popular for their soft, cradling support and exceptional motion isolation. These innovative mattresses are made of high-density foam that gently molds to your contours, providing superior pressure point relief for the entire body. Memory foam is also naturally hypoallergenic, making these mattresses are a nice option for people with allergies. Memory foam mattresses are available in a wide variety of densities, so it’s easy to find the perfect fit.
For some people, the close contouring of memory foams makes them overheat during the night. So if you sleep hot but still want to enjoy the comforts of memory foam, consider a low-temp gel memory foam mattress, which has effective cooling attributes. It’s important to note that memory foam mattresses are thick, and do not allow for a lot of movement. So, if you prefer a bouncy mattress, memory foam is not for you.
Latex Mattresses
Latex mattresses are the ideal choice for people with allergies or sensitivities. Naturally hypoallergenic, these airy mattresses are resistant to mold, dust mites, dander, and bacteria. And since they are made from natural materials, latex mattresses are free from harmful chemicals that can irritate the skin and eyes. Many people choose latex for its incredibly comfortable sleep experience. It offers luxurious softness and comforting support, with a moderate amount of spring. Latex mattresses are available in a variety of styles, densities, and firmness levels, so you can easily find one that’s tailored to your needs.
Some consumers find the heavier weight of latex to be cumbersome, because adjusting these mattresses usually requires the efforts of two people. Although latex mattresses tend to be a bit pricier than other alternatives, their durability and healthy nature may make it well worth the money.
