As stated by former customers, the firmness of the mattress is entirely subjective – in the sense that most people said that it was just as firm as they’ve expected it to be. On the other hand, others said that it was just too firm. Usually, the weight of the user will play an essential part in how he/she perceives firmness. In addition to that, once you unbox the mattress, you can sleep on it right away. You don’t have to give it time, as it is the case with other mattresses. This might be inconvenient to some.

You have to take time and do research before making a purchase. And most importantly, you must determine what you need and what you expect from your new purchase. For instance, let’s say that you enjoy sleeping on a mattress that has a familiar bouncy feel. In this case, innerspring mattresses, such as the ones we included in our review section, are worth considering. But let’s have a closer look at some other essential aspects. Firmness and Density If you’re on the lookout for an orthopaedic mattress, then it goes without saying that you’re looking for a medium to firm level of firmness. If the mattress isn’t firm enough, it means that it is not an orthopaedic mattress – the two are connected. This is why you should check the manufacturer’s specifications regarding the firmness of the product. Usually, density applies when it comes to memory foam mattresses. If you’re considering memory foam, then you should get high-density foam if you want to enjoy a high level of support for your back. Motion Isolation The odds are that you’ve heard about the term motion isolation. And it refers to the mattress’ ability to isolate motion in a given area of the bed. That is to say; when you move on your side of the bed, your partner shouldn’t be bothered by the motion or noise. But is this important? It depends on the person. Some people find it crucial, as they are light sleepers and can easily be bothered during the night. But when the motion isolation level is low, then this would mean that your partner will be aware of your every move, which could be disruptive to both of you. Open spring mattresses aren’t that good at isolating the motion and the noise, so bear this in mind if you find this characteristic important. Comfort You want your mattress to be firm and supportive for your back. But at the same time, you want it to be comfortable so that you wake up well-rested and energetic for the new day ahead of you. And usually, the price has nothing to do with how comfortable a mattress is. The construction of the mattress should be suitable for what you have in mind. For instance, if you feel most comfortable when you sleep on a supportive mattress, you should choose a firmer model. Otherwise, you will sleep in an awkward position and be disappointed with your purchase. When Should You Replace Your Mattress? This is a good question. Getting a high-quality, new mattress is an investment. So, you should factor in some guidelines. As a rule of thumb, you might need to get a new mattress after using your old mattress for up to eight or ten years. It is needless to say that the overall quality and build of the mattress and materials will matter just as much. In addition to that, if you often wake up feeling unwell or your back is sore in the morning, then this might be an indicator that you should change your mattress. Also, if you simply think that you aren’t well-rested, then you might think of getting a new mattress. Final Thoughts Hopefully, after reading this guide, you know how to pick the best firm double mattress for you. If you think that this is the right option for you, you might consider our recommendations, as they are excellent products that offer an excellent price-quality ratio. But remember those firm mattresses aren’t for everyone. Only get one if you struggle with back pain, and you want a supportive mattress.
