Hopefully you have a decent idea of what exactly memory foam is, as I described in a previous article here. Basically, let’s say you put your hand on it and applied pressure, the memory foam would give in and conform around you. You can imagine how this might be applied to mattresses in a pretty cool way to allow for maximum comfort. It’s sort of like the opposite of sleeping on a wooden board. You of course want to find a good balance between something that is supportive and comfortable. Not all memory foam is created equal. Some memory foam gives in a little too much, some not enough, and others just right.
The main benefit of getting a memory foam mattress is that it contours to your body, which makes for a very comfortable experience. If you can imagine sleeping on your side, then you know how important it can be to have something that gives in. You don’t want a lot of pressure on your hips and shoulders when you are sleeping. That’s why memory foam was such an interesting and monumental innovation in the sleep and mattress industry. It allowed for the mattress to give in and form to your body, thus relieving any pressure points on the places that mattered the most. Sounds amazing, right? Well, it is actually pretty amazing, but it’s not without its words of caution of course.
A major complaint about memory foam is that you sink into it too much and it forms a crater over time. You almost feel like you are off balance when you are sleeping. While giving into your body is good, this effect is certainly not the best. If the mattress develops a crater, then it’s just not going to be a very comfortable situation. What you need to do is make sure the foam density is enough such that it will comfortable but also not develop a crater.
Memory foam also has the ability to sleep hot. That is not good either. It can also give off a bit of a chemical smell, which can go away but in some cases does not. If you can get around these couple of minor points, then you just need to make sure that you like the feel of memory foam. Most people do and end up pretty satisfied. Therefore, it’s a really great option for you.
