A perfectly sized mattress can go a long way in guaranteeing that you will enjoy pleasurable sleep night after night. A
king size mattress can provide you with the comfortable space you need to be able to sleep without feeling cramped, with enough room around the sleeping surface to accommodate a loved one or two who will share the bed with you. A king size mattress is 76 inches wide and 80 inches long so you and your partner can have all the room you need to be able to move around comfortably in bed without worrying that you will bump and bother each other unintentionally, especially when shifting from one sleeping position to another in the middle of the night.
These are the benefits that you will appreciate when you have a king-size mattress on your bed.
Generous Space
A king size mattress offers the most generous space when it comes to mattress sizes, with the California king size that is 4 inches narrower coming in at a close second. This size is 16 inches wider than a queen size mattress and offers a significant upgrade that you will be able to enjoy from the first moment that you use the king mattress. The extra space will make it possible for you to sleep in whatever position you prefer and still have enough room to spread out on the mattress without encroaching on your partner’s personal space. A king size mattress is an excellent choice for couples who want to sleep with their kids on the same bed, or for those whose pets regularly hop in and out of the same sleeping surface.
King size mattresses are your best choices if you want to experience the luxury of sleeping on an extra-thick surface. These larger sized mattresses are available in more profiles that have a thickness of 10 inches or more, which can have a significant impact on the comfort and support that you will enjoy while sleeping or relaxing in bed. A thick mattress can make it feel like you are sleeping on a deluxe hotel bed, which can help you achieve better quality sleep without tossing and turning for hours on end. The best king size mattresses are also great choices for people who have taller or more substantial body structures who will benefit from the generous support and comfort that the additional thickness will provide for continuous sleeping enjoyment throughout the night
Luxurious Bedroom Enhancement
A king-size mattress and bed can immediately upgrade the look of your bedroom into one that looks dramatically more luxurious. The generous measurements of the king size mattress will easily stand out in the bedroom and lend an opulent aesthetic that smaller mattresses and beds will not be able to provide. You can even use the mattress as a canvas to showcase your most prized bed linens to transform your sleeping area into an artistic-looking space.
Types of King Size Mattresses
The types of king size mattresses available today are classified according to the materials used in creating the mattresses.
Foam
Memory foam is one of the most common types of foam used in king size mattresses today. These mattresses have a high-density base that works to keep the body supported to promote correct spinal alignment for every sleeping position so that discomfort due to poor posture can be prevented. The memory foam material conforms to the shape of the body to deliver a comfortable hugging sensation.
Latex
Natural latex king size mattresses – using either the Dunlop or Talalay procedure – are created from the sap that comes from the rubber tree. The natural latex material offers a chemical-free option for your king size mattress that offers superb pressure relief, with the Talalay latex delivering a bounciness that makes moving on the mattress easier to manage. King size mattresses made from natural latex also sleep cooler compared to memory foam.
Innerspring
Innerspring king size mattresses feature steel coils that provide strong support and are often supplemented with thin layers of foam that provide comfort enhancement. The structure of the springs, however, usually produce too much noise and poor motion dampening which can result in sleep disturbance between partners sharing the same bed.
Hybrid
Hybrid king size mattresses combine a layer of steel coils with several layers of memory foam or latex. This results in a mattress that offers the strong support of the innerspring coils to keep your body stable in any sleeping position while delivering the comforting softness that your body craves to be able to achieve deep, recuperative sleep. These king size mattresses frequently come with cooling features to ensure that the sleeping surface will not heat up while you sleep for long hours at a time.
Features of High-Quality King Size Mattresses
The following are the qualities that you can expect from top-quality king size mattresses.
Comfortable
High-quality king size mattresses deliver maximum comfort by providing you with all the space that you need to be able to sleep comfortably in whatever position you desire without the cramped feeling. You can even shift from one sleeping position to another without bothering the deep sleep of your loved one sharing the same bed. A king size mattress is roomy enough to easily accommodate children you may want to sleep with their parents from time to time, or even on a regular basis.
Supportive
King size mattresses often come in thick profiles of 10 inches or more. This kind of thickness ensures that your body will be completely supported throughout the night while you sleep, or while you engage in other activities while in bed. The thick mattress can keep your body stable and help maintain proper posture regardless of the sleeping position you prefer.
Aesthetically Pleasing
King size mattresses come in dimensions (76 inches wide by 80 inches long) that result in an almost square shape. This profile makes is a wonderful choice for people who prefer the clean, uncomplicated lines of the nearly square bed to take center stage in their bedroom. The generous proportions also lend an air of luxury that smaller beds or mattresses cannot offer.
FAQs
Q: What makes a king size mattress more comfortable than smaller sized mattresses?
A: A king size mattress provides you with more space so you will not feel cramped regardless of the sleeping position you favor. You can spread out and shift positions without the need to limit your movements so you can enjoy the freedom of moving naturally on the generously sized sleeping surface.
Q: Is there a big size difference between a king size mattress and a California king-sized one?
A: The dimensions of the king size mattress is 76 x 80 inches, while a California king size mattress is 72 x 84 inches. Both sizes offer generous proportions, but the latter is narrower by 4 inches and longer by 4 inches than the king size mattress. This means that the California king size may be a more ideal choice for tall sleepers.
Q: How can a thick king size mattress make me feel more comfortable?
A: King size mattresses with thickness levels of 10 inches or higher provide enhanced comfort by keeping your body fully supported to maintain proper back alignment. This will prevent the discomfort that can come from your spine being curved unnaturally when you sleep on an unsupportive mattress.
Q: What is the best material for a king size mattress?
A: It depends on your needs and personal preference. A memory foam king size mattress is a great choice if you love sleeping while being surrounded by a hugging sensation as the material conforms to your body’s shape. Latex, especially the one manufactured using the Talalay method, is an ideal option for those who sleep hot because the material offers superior breathability. A hybrid king size mattress will work marvelously if you want the strong support and comforting plushness in one product.
