Mattress manufacturers design and engineer various coil systems and comfort layers of foam to the mattress so it will conform to natural curves of your body and to keep the spine in alignment when you lay down. Pay close attention to how your hips and shoulders feel while taking a rest test.
Another important feature is good perimeter edge support. This feature allows maximum sleeping surface all the way to the edge of the mattress and a more comfortable seating edge.
When buying a new mattress you are buying three major components:
The upholstery layers are the comfort layers in the mattress. Mattress manufactures have found that adding more and better quality of comfort layers of foam will give you a more comfortable sleeping surface and a longer life span for your mattress.
The different layers in mattresses can be man made foams or natural fibers. There are many different types of foams. Every bed can have approximately 3-8 layers of padding and each layer can be a different material. Wool, cashmere, silk, visco memory foam, and latex foam are more commonly known and usually mean a better quality padding, but keep in mind that there are different grades of each of these different materials, which can affect the price.
The innerspring coil unit is the base of the mattress. It allows even distribution of your body weight while you sleep. The innerspring is steel so it will hold its strength for many years. The coils are what support your body in places where you need it most.
A box spring or foundation is an important part of the sleep system. A mattress and box springs are designed, tested and proven to work together. It's not the mattress alone, but the total sleep set that is designed to provide to provide proper support, especially for the new non-flip mattresses. Most sleep sets are designed to work with a particular style box spring or foundation. A proper foundation or box spring will properly support your mattress and improve the overall durability of your sleep set.
Discovering mattress value: It's what's inside that counts when shopping for a mattress, the design and quality of the components inside the mattress are what makes it feel and perform properly. Determining what's right for you is simple. Find the features that deliver the most benefits within budget. Compare the quality of the support systems as well as the comfort materials (the foams and fabrics).
Basic economics tell us that value is not the cheapest price but how many features and benefits you receive for the price. Higher price usually means more features and benefits, which means better support and comfort. So invest in yourself. Buy the best quality sleep set your budget will allow. You deserve the best.
