Reviewing 6-Inch Medium Firm Mattresses


Our review process

No more trying to get through confusing articles and infographics to try to decide which 6-inch medium firm mattress you need! By reading this guide, you'll have an excellent understanding of what kinds of mattresses are available on the market, so you can confidently buy a mattress that will ensure comfortable sleep for years to come.

Before buying a 6-inch medium firm mattress, there are some important facts you should know. Medium firm mattresses are built with an indentation load deflection ranking of 29-31 pounds and are great for people who switch from their back to side when sleeping. They are perfect for couples where one likes to sleep on their side and the other on their back or stomach. However, they can become lumpy or sag with extended use, so it's possible that they'll be less comfortable and supportive since your body won't be aligned well.

6-inch mattresses can be carried easily thanks to their compact build. Great for trundle beds due to their slim nature, they are convenient for guests and sleepovers. They are suitable to use with standard-size sheets, so you can easily find linens and other bed accessories that fit. However, 6-inch mattresses tend to wear out quickly, so they will need to be replaced more frequently. In addition, they provide less support than other types of mattresses, negatively affecting the quality of your sleep.

They are ideal for couples, with a tight fit between the two sleepers. However, full-size mattresses are short in length, so they may not be a convenient option if you're 6'3" or taller.
