It really makes sense to replace your worn out mattress, especially if it's a sprung mattress with its fillings and springs popping out in all direction. I mean, honestly, who would want to sleep on something like that - a bed with its innards hanging out?
However, the more important question here would be: who would want to sleep on a sprung mattress these days? Even the innocuous single layer or double layer foam mattress should be replaced immediately. This is especially true when there is no more amount of fluffing that can bring back its original comfort (not that you can fluff it anyway.) After all, who wants to sleep on a foam mattress that feels like a blanket?
Even the comforter would feel a heck lot better. And yet again, who would want to sleep on something like this when there are obviously better options out there?
If you really want value for your money, you may want to look into the direction of memory foam mattresses instead. True enough, some brands of memory foam mattresses can cost you a pretty penny; and yes, there are imitation labels that are after you for a quick buck. Overall though, good quality memory foam mattresses should address all the issues you have with your other bedding materials.
The key to buying a really goof foam of this kind is to make some Internet research on both the product and the distributor. Good indications of quality are money back guarantees and product guarantees of up to or more than 5 years. Anything less than that can be considered a sham.
As to the actual bedding material itself, comfort is always an issue. As most experts would agree, the best way to actually get comfortable with a bed is to lie down on it. Many of us judge comfort on how the actual materials feel on our body. A memory foam mattress conforms to the outlines of the body, making sure that comfort is achieved. More importantly, it helps distribute your weight throughout the entire mattress so that don't have to worry about the surface being too hard or too soft. This is actually a common problem with the air space beds and some brands of water beds. Memory foam mattresses can be both comfortable while offering better support, particularly around the lower lumbar area.
Backaches are quite common among people who are in their late 20 and above; and it sure does not help if the pain begins as soon as you wake up. We can definitely blame the mattress for that. Most mattresses may provide comfort, but it can add stress to the lower lumbar region of the spine. If you must know, the correct alignment of the human spine is not straight; it should be curved around the lower region. A memory foam mattress will give the person allowable movement while cradling the spine in a curved manner. Not only will this help falling asleep become a faster process, but it also makes keeps the appearance of backaches at bay.
