Aspects To Consider

Wondering what aspects you need to consider before deciding if you should commit to buy a king-sized mattress? Here are a few factors that are worth considering before clicking on “Buy Now”.


The comfortability of the mattress would depend on factors like material used, softness, firmness, support and airflow. Certain memory foam mattresses are known to heat up with body heat and this would make sleeping uncomfortable but mattress manufactures have made great technological strides with trying to combat this particular heating issue so customers now have many choices of mattress made with cooling materials.


You should also take into consideration what sort of firmness you prefer with your mattress. Since there are many preferences for the sort of firmness a mattress requires, you will be spoilt for choice as you can choose between firm, medium or plush for your sleeping needs. Identifying how you would like your mattress to feel is also important, for example do you prefer to your body to sink down into the mattress or float with adequate support? This factor would help you decide if you prefer memory foam, latex or a hybrid mattress.

For example, studies show that side sleepers prefer mattresses that are plush since they require more cushioning. Back sleepers require more support for the spine with cushioning so mattresses that are firm to medium plush is more recommended. People who prefer to sleep on their stomach require the most support and any mattress that is firm to medium is better for them.


While having a king-size mattress is great, you will need to consider other factors before finalizing on a purchase. Having the appropriate space in your bedroom to accommodate a king-size bed and mattress is important as you and your partner would be uncomfortable in a cramped bedroom.

Accounting to the sheer size and thickness of a king-size mattress, cleaning and changing the sheets off a mattress this size is quite the chore. Be sure you are able to handle the mattress on your own or ensure you can get help for this. Another detail to consider about owning a king-size mattress is the cost of purchasing one. King-size mattresses are quite pricey when compared to other smaller sizes.


Another element worth considering is the durability of the mattress. Most high-quality mattress come with a minimum warranty of five to ten years. Realistically a mattress should be replaced after five to seven years of use, depending on its quality. Really good mattresses can last up to ten years if the materials and maintenance is taken care of.

Purchasing a king-sized mattress is no small commitment as most of these large mattresses come with ten to twenty-year warranties. So while shopping for a new mattress is fun, you need to be sure of what you are looking for in a mattress to avoid disappointment. One useful tip is to know what sort of sleeping position you prefer: this can help narrow down your mattress choices.

2. The Casper Mattress by Casper

The company Casper made their mark on the mattress industry by committing themselves to the “study and science of sleep”. They are driven to help people to get the rest they deserve by creating mattresses that caters to the needs of the sleepless and they also improved the bed-in-the-box movement. Promising their customers “innovative sleep products”, their array of products might contain your perfect mattress.

First off, you will need to determine if you want an all foam mattress or a hybrid. An all foam mattress is plusher and has a “floating” feel to it where a hybrid would have a mixture of both support and firmness combined. A hybrid mattress usually made of both foam and coil springs to provide an extra firm feel for sleepers who need more than just comfort or body contouring in a mattress. Once you have determined which type of mattress is suitable to your sleeping needs, your mattresses shopping will be easier.


The Casper Mattress is twelve inches thick with four layers of premium foam and you get to choose between a mattress that is all foam or a hybrid of foam and springs (with added cost). The original Casper mattress (all foam) has a mixed foam feel, it feels comfortable and conforming while still giving you a slight “bounce” when in use. The “bounce” is important in a mattress if you do not want to have the “sink in” feeling and feel stuck.

The layers of comfort foam used in the mattress starts with a 100% soft polyester cover, followed by a breathable open-cell foam, to maximise airflow and keep you cool during sleep. Their open-cell foam promotes airflow and breathability to ensure you sleep in a comfortable temperature.

The following layers of support in the mattress is made of high density memory foam, zoned transition foam and durable support foam. These foams are optimal for body support and with the mixed use of foams the amount of support and pressure relief provided by the Casper is said help elevate back and hip pain with no compromise to the comfortability of the rest of your body. People with special conditions like scoliosis and arthritis might find this feature incredibly helpful.

If you need extra firmness, you can opt to add in pocket coil springs that is available in the hybrid option. The added support of the pocket coils at the base of the hybrid mattress would provide “elevated support”, it would help you move in bed easier with the extra support. Also, the pocket coil springs can help you get out of bed easier and would be especially helpful for an older person who might have trouble getting out of bed.

On the firmness scale, the Casper is at 5 which is a medium feel mattress that has both support and plushness. The mattress is just right, with enough softness for comfortable sleep and firmness for back support. The Casper has good motion isolation, which is great if you or your partner move around a lot in your sleep as you will almost no motion transfer with this mattress. Motion isolation is crucial especially if you or your sleeping partner are light sleepers and easily awakened by movements in bed.

If you require a mattress with edge support, the Casper has a disadvantage because it has poor support at the side of it. Edge support is basically how much a mattress holds you up or pushes back against you when in use. Mattresses that have more edge support would reduce the sagging and falling feeling you get when you are at the edge of the mattress. Edge support also gives you a better brace when you are sitting at the side of the bed and is quite important for users who are pregnant, have joint pain or other conditions that makes it hard to get up from a mattress.

The Casper’s edge support is not optimal and has a sagging feeling with almost no push back when you attempt to get up from the side of the mattress. You might have to take this con of the mattress into your purchasing consideration especially if edge support is something you really require in a mattress.

All of the foams used in the Casper are CertiPUR-US® certified, which means that the foams are made without ozone depleting chemicals (refer to FAQ for more details on CertiPUR-US®) so rest assured the materials used in manufacturing the mattress are safe with no harmful emissions.

“Your comfort starts with our foam.” This is the general vision Sleep Innovations has for your sleeping needs and they are not afraid to “foam it up” when it comes to their products. Pun intended. So let’s talk about the foam that Sleep Innovation uses for their Shiloh mattress.

The Shiloh comes with two layers of memory foam, the first layer is their SureTemp™ memory foam, an open-cell formulation of foam that supports you while allowing cool air to flow through the foam and heat to flow out.

The Shiloh is recommended for users with any sort of sleeping position as it has a rating of 5.5, giving it a medium support feel. The mattress is firm enough to support active sleepers and conforms easily to the sleepers’ body providing a “cradle-like” feeling night after night.

Bamboo charcoal has been used for a long time to absorb and eliminate unpleasant odours which is a great addition to have in your mattress because a mattress is used almost every day and you might not be able to help or improve the freshness of the memory foam or latex materials in it.


Having the bamboo charcoal infused into the foam helps to keep displeasing odours away and maintain a certain clean air around your sleeping area. Bamboo charcoal also works as a tool to absorb VOC (Volatile Organic Compound) which is basically vapours from organic chemicals that are emitted in room temperature. If you have sensitive sinuses or breathing conditions like asthma, having bamboo charcoal in your mattress will be really helpful for you to breathe cleaner air and get rid of any harmful chemical emissions in your bedroom.

In terms of comfortability, the layer of memory foam infused with Bamboo Charcoal provides soft plushness and gives a gentle “sink in” feeling. There is a relative amount of comfort from the first layer and the bamboo charcoal also helps to regulate heat so you will keep cool while in bed.

The main support layer of the mattress consists of 5.5 inches of pocketed spring coils that adds to the “bounce” of the mattress. The spring coils are individually wrapped so these are great for improving the airflow of the mattress. These special coils are supported by high density poly-foam which greatly improves the edge support of this mattress. The spring coils with the combination of the poly-foam would mean that it will easier for you to move around in bed since the push back would be good and with the good edge support it will be a lot easier for you to get up from bed and avoid the “sinking or rolling off” feeling.

The LUCID 10-Inch Hybrid Bamboo Charcoal and Aloe Vera has a rating of 6.5 on the firmness scale which is medium firm, providing good pressure relief while still able to support the user on the surface without sinking too deeply. This mattress is recommended for side and back sleepers as the support is better for the pressure points of these sort of sleeping positions. The mattress would seem a little soft and lacking in firm support that is required for stomach sleepers. So if you are looking for a mattress that caters to side and back sleeping positions, this is a good choice of mattress to consider.

The motion isolation is good for the LUCID 10-Inch Hybrid Bamboo Charcoal and Aloe Vera mattress as the infused memory foam distributes the motion transfer well on the surface of the mattress and the pocketed spring coils work well to isolate any movement made on the mattress.
