The Luxury of a Memory Foam Mattress Topper King Size

If you've got the floor space to accommodate the generous size of the mattress and box spring, a memory foam mattress topper king size version would be the ultimate spacious comfort. A double foam mattress memory topper king sized would be rather expensive, whereas a topper would provide the same luxurious sensation but without the high price to match.

There are several reasons you may want to add a memory foam mattress topper king size to your bed, with the first usually being the overall comfort factor. Some memory foam mattress toppers were designed with firmness in mind, while others are meant to offer softer support. Because of this, it's important to learn the jargon used in the silent night memory foam mattress industry so you'll know exactly what it is you're buying.

The Density Of A Memory Foam Mattress Pad King Sized

To determine a mattress topper's density, the weight of each cubic foot is used, therefore, a topper with a three pound density would weigh three pounds per every cubic foot. As you can imagine, a simmons beautyrest memory foam pillowtop made completely of memory foam would be quite heavy, especially the queen and king sizes, making them cumbersome and unmanageable, yet another reason that toppers have become a popular alternative.

In essence, the higher the memory foam's density number, the more firm and supportive the mattress topper will be.

When it comes to firmness, there's also the ILD to consider, or the Indentation Load Deflection rating, which roughly tells you how much weight is needed to compress the mattress topper by a percentage of 65 before it will spring back into its original shape again. The more weight required to make an indentation or impression in the memory foam mattress topper, the higher the IDL and the firmness will be.

Another term you may see is IFD, or Indentation Force Deflection, which was also coined to indicate the firmness or softness of a memory foam mattress topper. IFD measures the number of pounds needed to cause an indentation in a four inch thick piece of mattress foam topper king memory by a percentage of 25. While this indication can be rather accurate for assessing a topper's firmness, not all brands carry the rating.

The Length Of A Mattress Topper King Visco Elastic Memory Foam

In terms of width and length, a memory foam mattress topper king size measures 76 by 80 inches, while the California king version would be 72 by 84. Because some brands of toppers are a bit smaller than the conventional mattresses they're intended to sit upon, some people prefer to buy the California size for their king sized beds to ensure they both meet edge to edge. With this option, however, you'll more than likely need new bed linens to accommodate the topper.

Most memory foam mattress toppers are designed to last anywhere from five to 10 years, with those with heavier, denser foam lasting a bit longer, provided, of course, that they are cared for properly.

You will definitely want to invest in a cover for your memory foam mattress topper king sized pad as any exposure to moisture will certainly ruin the material. In fact, some warranties are null and void if the mattress topper isn't used in conjunction with a cover and the pad itself is exposed to liquids or body sweat, breaking down the sensitive material and rendering it ineffective, leaving you no choice but to purchase yet another topper.
