Firmness Info

The Ultima is available in 3 different firmness options:

  • Soft feel (3/10 firmness) Recommended for side sleepers, and those with a smaller build or weight.
  • Medium feel (5/10 firmness) Recommended for back and side sleepers and those who change positions throughout the night.
  • Firm feel (7/10 firmness) Recommended for front sleepers, average to heavier body frames, and people with back problems.

The Nectar Premier Hybrid is a medium-firm mattress. That's right in the middle of the firmness scale (a 6 to 6.5), where you get the most comfort and support.

The Simba Hybrid Pro is medium-firm in feel, however, because of the dual spring layers and wool layer the Pro provides a slightly softer, plusher, more luxurious feel than the Hybrid. 95% of Simba sleepers love their mattress. If it doesn't work for you, Simba mattresses that are returned are either refurbished or recycled; they never go near a landfill site.

Comfort Info

The Ultima has an innovative thermic cover that has been tested to reduce temperature by 2 degrees. Additionally, the continuous passive and dynamic airflow designs inside the mattress ensure optimal sleeping temperature.

Experience unparalleled comfort, with the heat-wicking cover and breathable open-cell CertiPUR™ foams, and you won't be disturbed by your sleeping partner thanks to the motion isolating properties of the layers.

Added springs and layers provide a plusher, more luxurious feel, even better heat regulation and ultimately an even more comfy night's sleep. Meaning there's now a Simba for a wider range of needs and budgets.

Two layers of springs means absolutely no sleep disturbance when your partner shifts and turns.

Support Info

The Ultima offers an incredible 6,000 nano and pocket springs in twin layers for the highest quality support, cushioned with luxurious layers of premium memory foam.

With unique 'wave technology', this ensures the right levels of support and pressure distribution, which helps to provide better spinal alignment while you sleep. The zones cater to various areas of your body supporting your head and neck to keep the head inline with your spine, a softer sink under the shoulders to relieve pressure and provide support, hip support, and zonal lower leg and foot support helping to keep your body aligned.

Deep springs, micro springs and memory foam in the Premier Hybrid deliver zonal support to relieve common pressure points beneath your shoulders, hips, and legs for better spinal alignment on all body shapes.

More Aerocoil® springs means even better body weight distribution for that plush, lush, gravity-defying comfort.

Refreshing Open-Cell Memory Foam
The ultimate comfort layer - the innovatory, large open-cell structure memory foam allows for 4 times the airflow for optimal breathability and comfort.

Dynamic Airflow
The dynamic airflow system actively and continuously draws fresh air into the core of your mattress, and engaging with the springs layers, pushes cool air up and throughout the mattress.

Dynamic Support layer
This layer enhances air flow, regulating your body temperature.

Micro-Springs layer
Is custom designed to draw heat away from your body and circulate fresh air with every move you make.

Natural British Wool Layer
Wool is hypoallergenic, naturally temperature regulating and moisture wicking and a dream for hot sleepers. Whatever the season you can rest cooler in winter and warmer in summer.

Open Cell Graphite Infused Simbatex Foam
This foam is infused with graphite, a natural mineral which draws heat away from the body for enhanced cooling. Furthermore, the open-cell nature of this Simbatex foam allows thirty times the airflow of viscoelastic memory foam.

Aerocoil® Springs
The conical design of the springs means they are cone-shaped and allow for greater airflow between the springs. The Pro has two layers of these micro springs which means twice the airflow!

Positioning Base Material

Aerocoil Spring Layers
The Pro has a double layer of springs, with up to 5,000 titanium Aerocoil® springs in total. This double serving means full and total body support. The top layer provides initial soft comfort and the second layer gives more gradual support. These two layers of 25mm conical pocket springs are made with titanium alloy, manufactured in Leeds and are enclosed in a 100% polypropylene pocket.

Edge to Edge Support Foam
The Edge Lift Technology or high definition foam with edge support means you won't get that feeling of rolling or falling off the bed when sleeping or sitting on the border.

Multi-Zoned Foam Base
A zoned support base provides different levels of support to different areas of your body to reduce pressure points. These nine customised zones adjust as you move, helping to keep your spine in perfect alignment.
