The answer is “yes”. Mattress thickness is a hugely important factor that you should consider before you make any purchase. A thicker mattress will usually offer more support and comfort, but there are a number of different factors that play a part in the design of a mattress. For instance, is it a hybrid design?
In this guide, we’re looking at the ideal thickness for mattresses and whether or not a certain size is for you. We also look at the dimensions of popular bed sizes, what thickness they are likely to offer, and how to measure mattress thickness to know what you are dealing with.
What makes mattress thickness and how to measure it
When you’re trying to work out what thickness memory foam mattress is best for you, you should consider the different layers within. The thickness is created by the layering that goes on inside mattresses. The different layers have their own functions, whether it be for your comfort or to take more of your weight. Some layers may be purely to keep you cool on hot days.
Before we look into a mattress thickness guide, it is worth fully understanding what makes up this size. What is within that 10 or 12 inches of mattress? Is a pillow top mattress thickness higher because of what is on the top? We discuss the layers and the average mattress thickness below.
As you probably know, most mattresses have springs. The support layer is where these springs will be located. They help to give support and spread the weight of a person laying on the bed. Obviously, springs aren’t comfortable to lay on, so the other layers make the bed far comfier.
The support layer often also has high-density foam which can be called reflex foam. In extreme examples this is used instead of springs and gives all of the support properties.
The comfort layer is the closest to the surface. Different brands use different materials to create a comfy surface for people to lay on. There are lots of different options. Often, natural fillings are popular. Things like wool or cotton, or even horsehair can be an ideal way to stay comfort, especially for people who stay in the same position while they sleep. Latex, which is durable while also comfy, is another popular material.
Foam layers may be used to give extra durability and a really soft finish, but it does mean that the mattress tends to be more expensive. The same applies for memory foam. These comfort layers are great for handling pressure points and giving a finish that keeps you comfortable all through the night. Some comfort layers also include things like gels to keep you cool if you live in a warm environment.
Mattresses have a number of covers. Some manufacturers even let you choose what cover you would like.
Knitted covers offer a fabric with elastic properties, they’re popular on memory foam models and they are breathable so even in hot environments they are suitable.
Damask covers have a hard-wearing design that is woven. They can last a long time.
Tufted and quilted covers also provide you with an extra level of warmth. This is ideal if you need to snuggle up to get warm on a cold winter’s night. Covers are often washable and replaceable so if you experience any issues with your cover, you can buy another. You might even have warmer covers for different times of the year.
