Each offers different characteristics to give the consumer a comfortable mattress.
But in order to review Kingsdown mattresses and then decide if they offer good value for money one must understand the niche market that Kingsdown fills.
Companies like Sealy and Serta are well-known in many countries and many consumers feel confident when buying their products.
However, Kingsdown is a small, independent mattress manufacturer that specializes in making mid- to high-end mattresses.
The company has also been in business a long time; over 100 years.
Over the last 30 years there have been many new designs of mattresses using many different technologies.
We have seen the rise in popularity - and then fall - of water beds; we can now buy air mattresses like the Simmons Luxaire mattress; pocket coil spring mattresses like the Beautyrest Pocket Coil system, also from Simmons; the latest innovation of memory foam mattresses from Tempur Pedic; and the marrying together of conventional mattresses with memory foam from Sealy and others.
Kingsdown does not manufacturer any of these types of mattresses.
Instead it sticks to what it knows best; innerspring mattresses.
This is no bad thing as over 90% of mattresses sold use the conventional, inner-spring coils.
The plain truth is that most consumers feel more comfortable sleeping on an inner-spring coil mattress.
What Kingsdown does is try to make the best, most comfortable mattress in the mid- to high-end price range.
Kingsdown mattresses use good quality materials but so do all of its rivals.
What Kingsdown claims makes its mattresses better than the rest is the use of computer technology in the design process of its mattresses.
The latest offering from the company is the Kingsdown Body System mattress.
The coil springs and the materials used are no better than other comparable manufacturers but the company claims that it will be the most comfortable you can buy when used in conjunction with its Dormo-Diagnostics Sleep Machine.
Basically, the Kingsdown Dormo-Diagnostics Sleep Machine is a computer system that analyses your body shape, and weight distribution and uses this data against measurements from the result of studies involving millions of people, thousands of mathematical formulas and 18 key statistical measurements.
The system is available from all licensed distributors of Kingsdown mattresses and only takes a few minutes to do.
A data read out will advise you on the Kingsdown Body System mattress that best suits your requirements.
Whether or not a machine can do a better job of choosing your mattress than your own judgment is debatable but maybe it can? After all, when choosing a mattress you're supposed to lie down on it for at least 15 minutes, try out your various sleep positions, and, ideally, lay down on it in your pajamas - or whatever else you sleep in.
Doing this is not easy as most consumers feel very self conscious when lying down on a mattress in a busy department store.
Many people sleep with a partner and Kingsdown have designed a mattress especially for couples: the Kingsdown Partner Perfect.
The company claims this mattress is the best and most technically advance mattress for couples.
I doubt this is true.
The biggest problem with traditional inner-spring mattresses is wave-motion.
This is movement felt by one partner when the other moves.
This movement is inherent in all inner-spring mattresses because all the coils are interconnected.
The wave movement is more pronounced when one partner is significantly heavier than the other.
If you have this problem you might be better off looking at other types of mattresses like memory foam from Tempur Pedic or a pocket coil system from a manufacturer like Simmons.
Finally, the company makes the Kingsdown Plush Sense mattress.
The main selling point of this mattress is the ProEdge Spring System in the mattress and box spring.
The claim is that the ProEdge gives greater comfort with a perimeter that is 20% firmer so giving better edge to edge support.
Does a firmer edge give better support? Probably not but some consumers do like mattresses with firm edges.
If you like a firm edged mattress then the Kingsdown Plush Sense mattress is a good choice.
Kingsdown do manufacture top rated mattresses and many reviews of Kingsdown mattresses are highly favorable.
Before buying a quality mattress you should decide what type best suits your needs.
If you prefer traditional, inner-spring mattresses then a Kingsdown is probably as good as Sealy, Serta and Simmons mattress of the same type.
