Innerspring mattresses, which account for 90 percent of the 21 million beds sold last year in the United States, are pretty much all made the same way: Steel coils are surrounded by padding, and the whole mattress is wrapped in upholstery. The innerspring coil unit is the base of your mattress. It allows for even distribution of your body mass while you are lying down. The innerspring, often called the coil, is helixical in structure and as such should hold its strength and shape for many years. The coils are what offer support to your body where you need it most.
But not all innerspring mattresses are the same. You can determine quality by looking at coil count, wire gauge, and the thickness of a mattress. A retailer should have the manufacturer's specifications for each model it sells - don't be afraid to ask. Choosing a Sealy, Serta, Kingsdown mattress, or other top quality mattress, isn't made any easier as each of these manufacturers offers different combinations of coil count, wire gauge and materials.
Realistically, there are just too many variables in coil design, function, and durability for consumers to understand what they are getting without spending days on coil research. However, you can be assured that all of the premium mattresses like Simmons and Kingsdown have a good innerspring unit. So, if you want a quality mattress that will give you a good night's sleep you should buy a mattress from one of the big, reputable companies and spend the most you can afford. But each mattress does feel different so you need to be sure that you choose the right one for you.
When you go to a mattress store don't be shy about testing out the mattress. A good idea is to go wearing clothes that you feel extremely comfortable in. Then, lie down on the mattress to see how it feels. Spend at least ten minutes lying on top of it. A good tip to check if the bed you are lying on is too soft, too hard, or just right is to lie on your back, placing your hand in the small of your back and then trying to move it about. If it moves too easily, the bed may be too hard for you; if it's a struggle to move your hand, then the bed is too soft. If you can move your hand with just a little resistance, the bed may be just right for you.
Also, don't just lie on the mattress. Toss and turn as you would do when you sleep. How does it feel in each position? If you normally sleep with a partner, then have them lie down on it too. Have them move and check whether their turning disturbs you.
If the thought of testing out a bed sounds a little too hit and miss you could try the Kingsdown patented computer system - called DormoDiagnostics - that they claim takes the guess work out of choosing a mattress. It scientifically determines your unique body profile, and specifies the Kingsdown mattress that is best suited to your needs.
Whatever mattress you choose, whether it is a Sealy, Jamison or Kingsdown mattress, take your time in choosing it. Buying a top rated mattress is an expensive business and you will also spend a third of you life sleeping on it; two important reasons to make sure your happy with your decision.
