Another one of the most important aspects to consider when determining how to choose a mattress is the level of firmness you prefer and require. There are generally three options: soft, medium, and firm. Each option is suitable for different needs.
First, you may prefer the luxurious feel of sinking deep into your mattress after a long day. If this is the case, a soft mattress may be right for you. Additionally, those with hip and joint pain prefer softer mattresses to relieve stress in those areas. Memory foam mattresses are one of the softest types. However, even an innerspring mattress can be pretty soft if enough plush layers are on top of the springs.
Medium-firm mattresses are excellent for those who move around a lot in their sleep, as they provide many options for support. Side sleepers also tend to prefer medium-firm mattresses, and they're an excellent compromise for couples with different comfort levels.
A firm mattress usually has 1- to 2-inches of plush or foam material on top, as opposed to softer mattresses which typically have about 4-inches of extra layering. If you suffer from frequent back pain, particularly upon waking, a firm mattress is the most likely to alleviate your symptoms. They help reduce pressure points in the shoulders and hips and promote healthy spine alignment. If you sleep on your back, consider a firm mattress for the ultimate support and better mornings.
Of course, sometimes, the level of firmness in a mattress simply comes down to comfort. While some people prefer that sink-in, surrounded-by-cushion feeling, others prefer a firm surface for a better night's sleep.
Mattress's firmness has a universal industry rating. The industry rates firms on a scale of 1 to 10, with 1 being the softest and 10 the most firm. Anything above a rating of 6.5 is considered more firm, while anything under that number will be softer.
