Firmness Info

Choosing your perfect mattress is all about your own personal preference. With Brook + Wilde you can choose a soft, medium or firm mattress.

Choose soft if you like sinking into a luxurious marshmallow-like mattress, the soft is supportive but with extra levels of coziness.

The medium offers the perfect balance of support and sink.

Go firm if you are looking for a firmer level of support while maintaining superior comfort levels. Less springy, but more supportive.

A medium-firm mattress perfect for all sleeping positions. the Emma NextGen is a 7 (medium) mattress on the firmness scale. For a softer feel, see the the Emma Luxe Cooling mattress.

The Simba Hybrid Essential is a medium-firm mattress, however, 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.

  • Support Foam (Wave Technology)

The Emma NextGen Premium Mattress is Emma's best selling mattress, featuring a 6-layer construction:

  • Supportive foam that relieves pressure
  • 7 different zones of pocket springs

The Simba Hybrid Essential is 20cm deep and contains all the Simba patented sleep tech that made Simba the world's most five star reviewed mattress brand. The four layers of the Hybrid® Essential are:

  • Breathable sleep surface (500g Hypoallergenic knitted cover)
  • Open cell graphite infused Simbatex foam
  • Up to 1,500 25mm conical pocket Aerocoil™ springs, enclosed in a 100% polypropylene pocket
  • Multi zoned foam support base.

Comfort Info

Should your Brook + Wilde mattress feel too soft or too firm for your liking, you can swap it with one of their other mattresses, free of charge, or select a refund in full.

Improved infinity pocket springs with a breathable layer of Point Elastic Airgocell® foam work together to create a sleep environment that is both cool and comfortable all night long.
The increased size of the springs allows for improved airflow. The Point Elastic Airgocell® foam absorbs and evaporates sweat, further regulating your temperature and ensuring a restful night's sleep.

Each individual Aerocoil® spring flexes gently in response to you and your partner's movements, offering personalised support to each of you without disturbing the other. And as they compress and extend with you, they gently push air through the comfort layer, helping to keep you at just the right temperature.

Support Info

Each mattress is ergonomically engineered to provide improved support to the neck, shoulders, hips and legs. These 4 zones offer different levels of support based on your body's needs. The neck support zone helps keep your head inline with your spine. The shoulder support zone gives softer sink to relieve pressure and provide support. The hip support zone looks after the natural curves of your body giving targeted lumbar support. Finally, the leg support zone gives lower leg and foot support to keep your body perfectly aligned.

The 7 different zones of pocket springs are tailored to provide optimal support for specific parts of your body (head, shoulders, chest, lower back, hips, thighs, and feet).

Combined with supportive pressure-relieving foam, our mattress provides exceptional support, aligning your spine and reducing pressure points for a truly restorative sleep experience, even as you change positions throughout the night. The reinforced core zone further ensures maximum spinal alignment.

Using body profile data from ten million sleepers, Simba's sleep scientists have created a mattress designed and crafted for every sleeping style and body type.

Comfort Specs

Thermo-Regulating High Density Foam
The unique open cell structure in the memory foam top layer provides a higher level of moisture evaporation and breathability, which helps your mattress to stay cooler for longer so you can sleep more comfortably all night long.

Point Elastic Airgocell® Foam
enhances breathability and regulates temperature by absorbing and then evaporating sweat. An additional layer enhances airflow and offers velvety softness.

Open Cell Graphite Infused Simbatex Foam
This layer uses an open cell foam, that allows thirty times the airflow of memory foam. On top of that, Simba have infused it with a naturally occurring mineral called graphite; that draws heat away from your body.

Support Specs

Thermo-Regulating High Density Foam
This HD foam supports your spine easing stress on those pressure points.

Support Foam (Wave Technology)
This specialist foam has cushioning qualities and relieves pressure points. The added depth and density it provides aids spinal alignment and your shoulders.

Pocket Springs
The first pocket spring layer has 1,000 springs engineered to move with you as you shift position to reduce pressure points. A second layer of 2,000 additional pocket springs give a little more push back and bounce. In combination, the spring layers work in perfect harmony giving you the right amount of support and bounce which can be lacking from foam alternatives.

Support Base Foam
This base gives structure and solidity to the overall mattress, in particular supporting the larger base layer of pocket springs.

Halo Memory Foam™
This memory foam perfectly adapts to your body shape for targeted spinal alignment, ultimate pressure relief and body-hugging comfort.

Supportive foam
A layer of foam to relieve pressure, promote proper spinal alignment and provide exceptional support.

7 Zone Pocket Springs
A layer of tall ergonomic pocket springs dynamically adapt to your body as you change sleeping positions throughout the night. Each of the 7 zones are designed to give personalised support for the different parts of your body.

HRX Supreme™ Foam
HRX stands for High Resiliency Extra. This counter pressure layer provides uniform support to keep your spine aligned, maximizing relief, rest, and recovery in any sleeping position.

The Simba Aerocoil® microspring comfort layer
Up to 1,500 conical springs work together to distribute weight whenever they feel pressure. They are smaller and slimmer than the regular tall chunky bed springs, and because they are made of super-strong Titanium alloy (manufactured here in Leeds), this magic metal means even a micro size (25mm high with a thickness gauge of 0.9mm, which is the size of a very thin paperclip) gives you the support you need, but being so small and fine you won't feel a single one.

Multi-Zoned Foam Base
With five separate support zones to make sure the base adjusts as you move, keeping your body in perfect, sleep-inducing alignment.

Fabric Specs

Removable, Washable Top Cover
The top cover can be unzipped and is removable and washable at 30 degrees. This four way stretch cover is breathable to allow for air circulation.

Memory Foam Protector
This protector allows the top cover to move freely and allows the memory foam top layer to work independently. No more friction between the fabric and foam which allows both components to work out their maximum potential.

UltraDry™ Original Cover
This award-winning cooling cover disperses heat and effortlessly wicks away any moisture. This premium temperature-regulating cover is removable and machine-washable and is made from 100% polyester.

The side cover is made of 100% polyester. The bottom cover is made of 85% polyester and 15% polypropylene.

What is the Cooling cover?
Upgrade your sleep with the advanced Cooling Cover, meticulously designed to boost the temperature regulation capabilities of the NextGen Premium Mattress.
This specialized cover surpasses our standard version with a unique cooling treatment that maintains a consistently cool sleep environment while adding extra comfort. Its user-friendly design makes maintenance effortless. Elevate your sleep quality and seize the opportunity for superior cooling comfort.

A 500g super soft, hand-knitted cover; this hypoallergenic sleep surface keeps your mattress fresh and cool. The cover is not removable or washable but you can spot clean it if you choose not to use a Simba Mattress Protector.
