Originally designed in the mid 1960's by NASA for passenger comfort and safety, memory foam bed toppers have seen a gradual increase in their sales as more and more people discover not only their unique feel and sturdiness, but also their springy protection. They mold themselves to the sleeper's body, and as the position of the sleeper changes, they gradually spring back to their original shape. This quality of the memory foam bed topper makes it ideal for people who have fit full sleep, people with back and spinal problems.

The mattress topper comes in various sizes and dimensions. The popular dimensions have been given names like Twin, Full, King, Queen, and Cal. While giving a luxurious sleep, it is also dust mite resistant, antimicrobial, anti bacterial, and even temperature sensitive. All these qualities help in inducing a flotation effect. However, every memory bed topper differs from the others. Here are a few things that you should keep in mind while picking one up.

• Pick the right size. This is the first consideration when it comes to buying a memory foam bed topper. The topper should fit your bed properly, and as the topper will sit flush on your bed, make sure you have the right dimensions that your bed doesn't look uneven. The memory foam toppers are sold in sizes of Twin, Full, King, Queen, and California King.

• Select the right density. Density is the weight of one cubic foot of the mattress. This is equal to the 'memory' your topper will contain. Toppers with high density will respond better to body weight, supply better protection, and are more durable. People usually pick toppers of 3 pounds, but those with back and joint problems will need a 4 pound topper.

• Choose the right thickness. These toppers are usually sold in thicknesses of 1,2,3, and 4 inches. While toppers with 2 inches will make you quite comfortable, those with higher thickness will make you bed feel different and new.

With all the different bed or mattress sizes out in the market today, it is no puzzle why some cannot decide on what to purchase.  There are twin beds, king beds and queen beds among the choices for the homeowner of today.  So, how do we tell these beds apart from each other?  It will all boil down to knowing their measurements.  Twin bed dimensions are different from king size bed dimensions and queen bed dimensions.  Once you have an idea on what the mattress is for, then you will be certain to pick out the correct size for your home.

Twin beds are also commonly referred to as single beds.  I know, confusing.  To set it straight, twin bed dimensions come in measuring 39 inches across and 75 inches long.  The twin bed is the common size usually found in dorm rooms and bunk beds.  Twin beds are perfect for use in guest rooms in the home.  One can also put in a trundle underneath the twin bed to provide additional sleeping space in the room.  Another plus for the twin bed is the availability of beddings in the market.  One never has to worry about what to put on the bed.  However, being a short bed, the length of the twin bed is often not enough for adults.  In this case, one can also try the twin bed extra, which is about five inches longer than the standard twin bed.

Are the twin bed and twin bed extra still not enough for your needs?   You can try fitting in a queen size bed or a king size bed.  If you are furnishing for one of the main bedrooms in the house, these two will fit in perfectly.  The queen bed measures in at 60 inches wide and 80 inches long.  If two people sleep on it, that is about 30 inches per person.  For the king bed, it comes in two varieties, the Standard King and California King.  Both are bigger than the queen bed.  Measuring at 76 inches wide by 80 inches long is the Standard.  While for the California-size, it is 72 inches wide by 84 inches of length.

The choice of mattress is yours.
