Mattress Size vs Mattress Thickness

Now that you know mattress measurements, another common question that arises is what about the mattress thickness. Does it come into play when choosing the mattress size and mattress dimensions?

Mattress size is about how wide and long the mattress is, like Twin or Queen. But when it comes to the thickness, it is almost like the underrated hero of mattress comfort. While size ensures you have enough room to spread out, thickness impacts how your body sinks in and receives support. It's all about finding the sweet spot between feeling hugged and feeling like you are on the floor.

The ideal thickness is a personal choice. However, factors like body type and sleeping style also come into play. Most mattresses range from 4 to 12 inches thick. So, you can go with the option that feels right to you.

Here's a quick tip: When shopping for a mattress, consider trying out different thicknesses to see what feels most supportive and comfortable for you. You can also opt for a mattress with trial nights to try it before you make a commitment. For instance, The Sleep Company offers 100 trial nights!

Additional Factors to Consider to Choose the Right Mattress Dimensions

Here are a few other factors you must consider when it comes to choosing the right mattress size and mattress dimension.

1. Room Size

Imagine a very large room and a single bed. Seems odd, doesn’t it? At the same time, picture a large bed in a small room. This feels almost claustrophobic, doesn’t it?

That’s why apart from considering your height, room size is important, So, before making a decision, measure the length and width of the room. You must make sure the mattress fits comfortably without crowding the space. Leave enough room for other furniture and also ample walking space around the bed.

2. Height Of All Sleepers

Don't only consider your height but the height of all sleepers. This includes you and your partner. Let’s say, you are 5’9 and your partner is 6’2. A double bed won’t suffice. Here, you will have to go for a queen.

3. Future Considerations

Choosing a mattress is a big investment. Therefore, consider any future needs that may arise. For instance, life changes or changes in family size must be taken into account.
