DLX Classic 12" Firm

GoodBed Expert Review
Our Take on DLX Classic 12" Firm

Founder of GoodBed
Michael Magnuson

Founder of GoodBed, Leading Mattress Expert

Bottom Line - Is the DLX Classic 12" Firm the right mattress for you?
Bottom line best icon BEST if you
  • Want a very firm mattress
  • Are either a stomach or back sleeper
  • Regularly sit or sleep along the edge of your bed (edge support is excellent)
  • Have a clear preference for sleeping 'on' your mattress rather than 'in' it
  • Want a mattress that helps you stay cool while you sleep
  • Prefer no 'memory feel' in your mattress
  • Can sometimes be disturbed by other movements in the bed (motion isolation is very good)
  • Want it to be as easy as possible to move around and change positions during the night
Bottom line not ideal icon NOT IDEAL if you
  • Are a side sleeper, especially if you weigh less than 150 lb
  • Don't like a lot of bounce in your mattress
  • May use this mattress on an adjustable base (adjustable base compatibility isn't the best, but is still pretty good)
  • Prefer some softness in your mattress
  • Want a natural or organic mattress (though this mattress is still pretty good in terms of avoiding harmful chemicals)

Additional Information

General Description

Two-sided longevity. Unrivaled comfort. All made possible with innovative technology and superior materials in the USA. Our Classic Mattress is ideal for sleepers who appreciate a consistent feel but want a choice in firmness level.

Mattress Construction:

  • Luxurious Hyperflex Fabric: This is the topmost layer of the mattress, which provides a soft, breathable surface that promotes airflow and a cool sleeping environment.
  • Airsoft Viscose Fibers: The next layer is composed of airsoft viscose fibers. These are ultra-soft and offer excellent temperature regulation, ensuring you stay cool throughout the night.
  • ¾” LoftAdapt Foam (Density: 1.8 lbs.): This layer provides initial body contouring, offering a perfect balance of softness and firmness for optimal comfort.
  • ¾” LoftAdapt Foam (Density: 1.8 lbs.): A second layer of LoftAdapt Foam reinforces the initial layer, further enhancing body contouring and providing pressure relief.
  • ¾” Refresh Performance Foam (Density: 1.8 lbs.): This performance foam layer is designed to provide deeper support and body-hugging comfort. It also enhances breathability, ensuring you stay fresh all night.
  • 8” Advanced Hybrid Spring: The heart of the mattress, this layer provides robust support to align your spine correctly and reduce pressure points. Its hybrid design also ensures efficient airflow, adding to the cooling performance of the mattress.
  • ¾” Refresh Performance Foam (Density: 1.8 lbs.): Mirroring the fifth layer, this foam layer offers deeper support and body contouring for the other side of the mattress when flipped.
  • ¾” LoftAdapt Foam (Density: 1.8 lbs.): A replica of the third and fourth layer, this foam layer provides body contouring and pressure relief when you opt to use the other side of the mattress.
  • ¾” LoftAdapt Foam (Density: 1.8 lbs.): An additional LoftAdapt Foam layer reinforces the initial layer, further enhancing body contouring and providing pressure relief for the other side of the mattress.
  • Airsoft Viscose Fibers: This layer, mirroring the second layer, provides extra cushioning, breathability and temperature regulation.
  • Luxurious Hyperflex Fabric: The bottom layer of the mattress (or the top when flipped) is made from the same luxurious Hyperflex fabric for a soft and breathable surface.
