Finding the most comfortable mattress can be quite challenging, especially if you’re sleep-deprived!
The secret to ultimate comfort lies in density and thickness.
This article is a buying guide for the best extra-firm mattresses.

The Soft Mattress: A Leading Cause of Back Pain?
Many people mistakenly believe that the softer a mattress is, the more comfortable it is.
As we get older, we learn this isn’t true.
Falling asleep on a soft mattress with poor support can lead to back and neck problems, especially for side sleepers.
Your spine needs to stay straight while you sleep to breathe properly and keep circulation as free as possible.
Other problems that can come from a soft mattress include interrupted sleep or sleep that isn’t very deep, leaving you feeling less refreshed in the morning.
When your breathing or blood flow is blocked, you likely won’t get enough oxygen to your brain, which prevents proper rest.
The worst part is that these effects tend to accumulate, leading to poor posture during the day.
Why Would Having an Extra Firm Mattress Help Me to Sleep Better?
Extra-firm mattresses have the density needed to support your weight and keep your spine straight.
This can resolve many hip aches, joint problems, burning or raw nerves, and stiff muscles.
We often create pressure points from incorrect posture, and sleeping in the correct posture tends to relieve them.
The main benefit of sleeping on an extra-firm mattress is getting a deep night’s sleep.
When you sleep well, you reduce pain and your perception of pain, and you have more energy during the day.
Your body needs time to rest to breathe better, improve blood flow to the brain and body, and reduce stress.
Extra-firm density mattresses also last much longer than soft mattresses, which are made to sink into but lose their plushness very quickly.
Features of a High-Quality Extra Firm Mattress
The best extra firm mattresses available on the market at the moment usually have one or more of the following features:
- Orthotic Design – some extra firm mattresses have notches, grooves, or ridges in odd places. These are usually placed there to alleviate pressure points on your back and help to keep your spine in place. Make sure you are the right size if a mattress has a built-in body-contour design.
- Memory Foam – everybody is looking to buy a memory foam mattress these days, and awareness of them is spreading like wildfire. Memory foam sinks in and sets its shape to match the 3D outline of your body! If you fall asleep on a memory foam mattress in a straight position, it can hold that shape all night with maximum softness and optimal density. Memory foam mattresses offer the best compromise between the softness we crave and the firmness we need.
- Multi-Layered – foam technology hasn’t stopped at memory foam, though. Some mattresses have multiple foam layers, each designed with a function in mind to aid your sleep and reduce heat or pressure build-up.
