The most basic mattresses can be bought almost anywhere at all, whether in mini outlets or in malls. Depending on the selection available, you should, preferably, check out as many mattresses as you can before settling on the right one for yourself. While firmer mattresses might seem uncomfortable initially, they might be able to provide the back support you need for health reasons. From a personal standpoint, I’d suggest getting a latex mattress due to the comfort and support that it provides but it might not necessarily be comfortable for you.
The same can be said of foam mattresses. Since most of them come with different properties such as being hypo-allergenic or having a 100% natural filling, you really should do some research first before getting one. If you’re concerned about your mattress topper, note that most of them come with different sizes as well as materials. For instance, some might be made out of feathers, cotton fibres, polyester or more (more about the different mattress types and choices can be found at http://www.mattressdebunked.com/). Of course, most importantly, you have to be sure that the mattress itself is suitable. Since you’re going to place a mattress sheet over it, you don’t have to be too concerned about what the surface feels like. Foam or its memory foam alternative will feel rough upon touch, unlike innerspring or latex types but that shouldn’t matter as much for this reason.
It is also rather common for mattresses to lose their spring or even foam elasticity over time, especially if they’re cheaper and of a lower quality. In such cases, your warranty might cover these defects and you could get them changed. This is precisely the reason why the better mattress companies will often offer extensive warranty periods. Airing the mattress from time to time is also important if it comes with a strong chemical smell after you unpack it for the first time. While the smell should dissipate within a day or two, wrapping it up in a mattress sheet or topper will cause the smell to be trapped in it. It’s highly suggested that you air these mattresses weekly by removing the topper and leaving it under the fan for a couple of hours.
For innerspring mattresses, you’ll need to know what the coil systems consist of. Most coils (especially the top layer) will be sturdily built and will wear down much slower over time compared to the bottom layers. The difference here is vital and the fewer coils there are in the springs, the less bouncy it would feel. For certain night activities, this can be important. The higher-end beds or mattresses may look as if they’re made out of spring, but you’ll be surprised. With the huge array of mattresses available today, some might even be filled entirely of air but they can feel just as comfortable as other more ordinary beds.
Air mattresses will be a good example here. Even some of the high end hotels are using air mattresses (and some even water) for their guests. Not only do these mattresses feel less “hot” when you’re sleeping on them, the firmness can be adjusted according to your whims so you’ll less likely find comfort problems with it. Plus, they’ll require less maintenance since what you really need to keep it as firm as before is to pump more air into it and make sure that the mattress doesn’t leak.
