This is probably one of the most common questions that often pop in our minds whenever we decide to purchase a mattress topper. And the answers, though greatly depend on your personal preferences, can be narrowed down by certain factors. The first thing that you need to consider is the firmness of your current mattress and how would you change your bedding to improve the quality of your sleep. And most of the time, your mattress topper will do a great job at softening the mattress and improving your overall comfort, with a suitable thickness between 2 to 3 inches. But that isn’t the only thing to care for, as the materials of your mattress topper should also be considered. If it’s a memory foam topper, you’ll find yourself enjoying a medium level of softness and excellent pressure point release, which is great for people with back pain. But don’t go for something that’s too thick, since memory foam can easily trap heat and moisture, making you quite uncomfortable during warm weathers. For latex toppers, you can choose whichever thickness that you prefer. This is largely thanks to their soft, breathable, and comfortable natures. Also, latex toppers help to reduce back pains with their pressure point release features. While feather and wool toppers can offer many similar features such as latex toppers, they tend to get flatten easily and will need to be re-fluffed every once in a while. So we don’t recommend you getting a thin topper, as it would beat the purposes of having a topper in the first place. And for a cheap mattress topper solution, the common fiber-made products can easily satisfy you with their adequate features. But since they tend to get flattened and lumpy over time and would hardly return to their original shape, you would want a relatively thick topper to at least being able to enjoy the offered features longer.
