What is an “extra-firm” mattress?

The typical scale of mattress firmness goes from 1-10. One being the softest and 10 being the firmest. A. extra-firm mattress typically ranges between 8-10 on the firmness scale. An extra firm style mattress is the firmest mattress you can get while still providing enough pressure relief and contouring for your body to sleep comfortably and healthily. The “extra-firm” realm of mattresses is perfect for those who lay on a standard firm mattress and believe it is not firm enough for them. 

What is the hardest mattress available?

The hardest or “firmest” mattress on the market is probably the Plank mattress by Brooklyn Bedding. The Plank is 2 sided and offer sleepers a firm and extra firm sleeping option. This mattress is built specifically for sleepers who prefer and ultra firm mattress. 

Is an extra firm mattress good for your back?

An extra firm mattress is suggested to be better for you back due to its supportive nature and proper alignment of the spine. However, if you are a side sleeper you pay opt for something a little less firm in order to allow for the proper curvature of your spine. 

What are the different types of extra firm mattresses?

Extra firm mattresses are available in a variety of different materials and styles. This allows for customers to still be able to choose a mattress that meets their comfort and material preferences even with the customized size specs.

  • Hybrid : A hybrid mattress is a fancy way of specifying that the mattress utilizes innersprings as well as foam. This gives the sleeper the traditional bounce and support of a spring mattress while also providing pressure relief and comfort properties of a foam mattress. 
  • Latex: Latex is known as the most “natural” option when is comes to mattress materials. Latex is poured form the rubber tree and is made without the use of harsh chemicals or additives that other products are made with. It is important to note that there are strict guidelines for mattresses in terms of chemical additives these days and many of the chemicals used in the past (such as Flame Retardant sprays) are no longer used on any mattresses.
  • Memory Foam: Memory foam has recently become very popular in the bedding market. The material was originally made for use by NASA and was ultimately used in mattresses due to its unique pressure relief and cradling properties. Memory foam has a very unique feel that some people love and others hate. If you have never tried sleeping on a memory foam mattress before it is important to note that the feeling it very different from a traditional spring mattress.

Extra-Firm Mattress Pricing

In general an extra-firm mattress utilizes less materials than a plush or softer pillow top mattress, therefore they tend to be slightly less expensive. The majority of quality extra-firm mattress builds will be around $700-$1200.  Latex mattresses are generally more expensive due to the higher natural material costs. 

Things to consider before choosing an extra firm mattress.

There are a variety of options when it comes to extra firm mattresses on the market and it is important to think about your specific needs when choosing which may be best.

  • Usage: How often will you be sleeping on this mattress? How long will it need to last? If you plan to sleep on this mattress for multiple nights in a row or want it to last for many years we recommend staying away from the entry level affordable mattresses. These entry level mattresses are intended for occasional use and won’t hold up as well as some of the higher end mattresses.
  • Sleeping style: Are you a back or stomach sleeper or a side sleeper. While an extra-0fi4m mattress may be great for a stomach or back sleeper you may want to opt for something slightly softer if you sleep on your side. 
  • Material: There are a variety of different mattress materials thart you can choose form when it comes to extra-firm mattresses. Latex is natural and will give more of a bounce feel. Memory foam conforms to your body and is great at offering pressure relief for joints. A hybrid mattress will feel most like a traditional innerspring mattress and will give amazing support while also conforming to the curves and movements of your body.

Should I use a mattress topper with an extra firm mattress?:

A mattress topper will make an extra firm mattress feel softer. We only recommend a mattress topper if you intend to make your mattress feel softer, not for making it firmer

Alternative options for purchasing an extra firm mattress?

If you prefer not to purchase your mattress online you can look for custom mattress factories in your area to build you a mattress you can test out before buying and build to your specific firmness level. A couple custom mattress manufacturers you can check out in person are:
