Who This Is For

King-size mattresses are ideal for large beds measuring 76 by 80 inches. They are an excellent choice for people who value a comfortable bed and restful sleep.

Hybrid vs foam

Hybrid mattresses have a coil system on the support core while foam mattresses have a polyfoam support core. Polyfoam cores produce less noise and perform better in motion. The Coil system, on the other hand, performs better for bouncing, breathability, and edge support.

Memory foam mattresses are cheaper than hybrid mattresses. They are also better for pressure relief. Alternately, hybrid mattresses have enhanced temperature regulation and are more responsive.

On the negative side, memory foam mattresses are susceptible to overheating and off-gassing.

Hybrid mattresses are heavier to maneuver and produce more noise and have more motion transfer potential.

Is it worth splurging on?

King-size mattresses give you more bed space, thanks to their large size. They also facilitate different activities such as comfort while cuddling with your partner and spending time with your children. With this mattress, you will also get better rest, since it gives you enough room and comfort.

You can also use this mattress to improve the appearance of your bedroom. They provide a dramatic flair that makes your bed a focal point and center of attention in your room. Therefore, a king-size mattress is worth investing in.

King vs queen – the difference in size and shape

A king mattress fits a king bed while a queen mattress is designed for queen beds. A king bed and a queen bed have equal width but vary in length. A queen bed measures 60 by 80 inches while a king mattress measures 76 by 80 inches. Therefore, a queen bed measures a total of 4800 square inches, and a king bed measures 6080 square inches. They both come in the same shape and only vary in length.

Care and Maintenance

Following the correct care and maintenance procedures for your mattress will increase its longevity. It will keep it from ripping and falling out of shape. Get a fitting mattress cover to keep it from getting dirty. Once the cover gets dirty, it will be easy to remove and clean it.

You can also get a waterproof cover to protect your mattress from water, food spills, and body excretions.

In case your mattress rips, sew it immediately to protect the seams and threads from running further. This way, you will keep your mattress in a good condition for longer.

If you accidentally or intentionally spill food or other types of dirt on your mattress, wipe it immediately. You can use a clean wet cloth to wipe the spills off before they run too deep into the mattress foam.

When you feel like your mattress is not even, flip it to the other side to allow it to thin evenly. If even after flipping it you still find it uneven or uncomfortable, then it is time to replace it.

Remember, such a mattress can hurt your back and joints which can in turn lead to long-term health issues.
