Super friendly and efficient service
Super friendly and efficient service. From when I placed my order all the way through to delivery, I was kept in the loop all the time. My mattress was even delivered earlier than expected. Thabani and Mbo even made sure they contacted me 30 minutes prior to delivery to make sure someone was available to receive the mattress. Well done to the Mattress Warehouse team on exceptional service.

Bed
I had a great experience with the Matress marehouse, I had ordered for DBN, 2 beds and Naushaad Razaak was beyond exceptional. Frequent updates and friendly engagements until the beds were delivered and constant check up post delivery to check how we are with our newly bought beds. Thank you Naushaad with your service. Much appreciated. I will be coming back for more.

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 Bed 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.

To summarise the Rest Assured Posture Guard Firm Bed:

  • Deluxe breathable surfaces
  • Better durability with dual tempered Bonnell
  • Hygienic & non-toxic

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.
