Ashley Sierra Sleep Limited Edition Firm Mattress Review

Updated November 10, 2022

The Sierra Sleep Limited Edition Firm mattress is a very firm bed designed for people who want a feeling that is almost like sleeping on the floor.  We’ve reviewed its features and highlights and have broken them down so that they are easy to understand.  If you are considering this model we're here to help you decide:

Comfort Scale Rating

The Limited Edition Firm mattress is rated a 1.5 out of 10 on our Comfort Scale (a 1 is hard, 10 is softest). This bed is very firm and almost feels like you are sleeping on a thickly carpeted floor. This mattress would work best for people who want an extremely firm bed.  If you want anything that's at least a little soft then you should consider a different model. If this is too firm, try the plush and pillow top versions of this mattress.

Pros & Cons

PROS CONS
  • Materials feature gel memory foam
  • Individually power-packed coils
  • Good bed for those who need really firm comfort 
  • Simplified shipping to your door

Pressure Test Results

We pressure tested the Sierra Sleep Limited Edition Firm mattress with large, medium, and petite-sized models while they laid on their back and side sleeping positions (Learn how we test.) 

Unsurprisingly, this bed didn't test very well because of how firm it feels.  Remember how we rated this bed a 1.5 on our 10 point comfort scale? Well, a rating of 1 on our comfort scale is literally the floor, hard and unforgiving.  This bed caused a lot of pressure in all body types and sleep positions which is why it earned a 'not recommended' score for 5 out of the 6 combinations represented below.  The red areas shown in most of the images show where there's an excess of pressure which causes discomfort leading to tossing and turning.  Furthermore, there is little evidence of proper back support which would cause lower back stiffness and even pain.

All of this only really means that the bed causes additional pressure on your body.  For those people who really like a very firm bed this information is moot, you'll like the bed just fine.

The Main Ashley Sierra Sleep Limited Edition Firm Features in Detail

Sierra Sleep Limited Edition Firm Cutaway

  1. 1. 1.5" Firm Support Quilt Foam 

    This quilt foam is the plush part of this bed which gives you some plush comfort while adding to this bed’s firm support.  This is the layer of material that “hugs” your body while you sink into the bed.

  2. 2. 2" Firm Support Foam

    High-density firm foam provides good body contouring, support, and motion transfer isolation, resulting in solid support with fewer disturbances due to partner movement.

  3. 3. 1/2" Gel Memory Foam

    The 1/2" of High-Density Gel Memory Foam conforms to your body’s shape and helps to relieve pressure points. This is especially important in the lumbar region because it helps with proper spine alignment.

  4. 4. Power-Packed Individually Wrapped Coil System

    The layer of 680 15-gauge Power-Packed Wrapped Coils conforms to any body type giving you stable support.  These coils are compressed before they get wrapped in a material so they provide more consistent support under your body for extra stability. 

Warranty

The Sierra Sleep Limited Edition Firm mattress has a 10-year warranty against factory defects.

Conclusion

The Sierra Sleep Limited Edition Firm Mattress by Ashley is a very firm bed. If you prefer a mattress with more softness or more plush feeling materials then you won't enjoy this bed. However, for those who prefer a very firm feel to their bed then this mattress is just about as firm as they come, you'll love this bed's feel! Try the plush and pillow top versions of this mattress if the firm does not work for you.

Our pressure testing has confirmed that this bed is not recommended for everyone with its very firm feeling.  In fact, this bed won't appeal to most people, just the ones who really truly enjoy a very firm feel to their mattress.  

This mattress is made with some premium materials like Gel Memory Foam and Firm Support Quilt Foam. Ashley Mattress has made this bed with quality materials while keeping it very inexpensive. The individually wrapped coils are also a better option than traditional tied-coil systems. They are more conforming adding to this bed's comfort and study support.

As firm beds go this model is a good choice.  The inclusion of some premium materials used in its construction, and the lower price, make this mattress a great value. Just remember that the feel will really only work for people who like a super firm bed and I wouldn't really recommend this model to anyone else.
