Ordering from The Mattress Warehouse was a great experience
Ordering from The Mattress Warehouse was a great experience. After placing my online order I received a follow up call from their office (unfortunately I cannot remember the lady's name but she was very professional and delightful) to confirm my order and double check my mattress choice. The delivery team, Mboh and Lwazi, were also very professional and efficient. Well done to everyone involved.

Description

Enjoy classic mattress comfort on luxurious fillings while supported beneath by the most traditional of coil systems.  Bonnell mattresses have displayed their value over time.  This soft yet firm bed is very stable and durable, promising full support night after night.  The virtually indestructible Bonnell springs provide uniform and consistent support without feeling too bouncy.  If you are looking for firm comfort, the Rest Assured Posture Guard Firm Mattress is a very good option.

Comfort level 2:  Firm

Ideal for the following sleeping styles:

  • Back sleepers
  • Stomach sleepers

Deluxe breathable surfaces
Moisture-reducing VISCOSE BREATHE blue gel and Hyper Soft polyurethane layers give the mattress its luxurious comfort and supportive feel.

Better durability with dual tempered Bonnell
Using heat and electronic methods to temper the Bonnell spring units means more rigidity and less compression as time goes by.

Active technology for more stability
The hourglass-shaped springs are hand-assembled and strategically connected to eliminate tilt and provide more stability.

Pre set to prevent sagging
You need not fear that your mattress will sag as you begin using it.  By compressing the Bonnell unit into a flatter position, the likelihood of initial sagging is ruled out. 

Heavy-duty 6 turn Bonnell
More turns in the Bonnell spring equals more strength.  This spring system gives 33% more working wire.

Stronger double knot
By knotting the springs at the top and the bottom, the springs can perform with more evenness and stability, and there is less risk of knot slipping.

Open-cell technology for more breathability
Polyurethane foams manufactured with an open-cell structure improve the ventilation ability of the mattress and encourage a more hygienic environment for a deeper sleep.

Soft knitted ticking
Enjoy the softness offered by the micro-quilted jacquard ticking which encapsulates the mattress. This durable outer fabric layer ensures comfort while dissipating heat.

Hygienic & Non-toxic
The foams, which are produced in-house at Strandfoam Group, are completely stable, hygienic and non-toxic.  

Quality dual-sided mattress
Providing the benefit of another sleeping surface, your comfortable dual-sided mattress will need to be flipped and rotated from time to time.

  • Deluxe breathable surfaces
  • Better durability with dual tempered Bonnell

Product Video
Firm
Beds with a firm comfort rating are great for certain sleepers. Firm mattresses give way a lot less under body weight, creating a firm and solid platform that allows perfect spinal alignment. People who like to sleep on their backs and stomachs will greatly benefit from sleeping on a firm mattress.
