Mattress Construction

Materials Overview
The Douglas Alpine mattress features a carefully selected combination of materials that prioritize comfort, durability, and environmental responsibility: * EcoLight Cooling Gel Foam: A proprietary foam that delivers superior cooling and pressure relief while using up to 40% less carbon input than traditional memory foam. * Premium Elastex Foam: A latex-like foam that is hypoallergenic and offers responsive support without the heat retention of traditional latex. * Motion-Isolation Support Foam: This dense foam layer reduces motion transfer, ensuring uninterrupted sleep for couples. * Machine-Washable Cover: The mattress is wrapped in a stretch-knit, breathable fabric cover made from sustainable materials for added convenience and longevity. These materials are not only high-performing but also eco-conscious, aligning with the growing demand for sustainable products.
The Helix Plus is designed for Plus Size and Big & Tall and offers maximum support with a medium feel, it has five layers of construction:
  • Tencel Cover
  • 1.5" Helix Dynamic Foam
  • 1" Gel Memory Foam (Density: 4.0 lb)
  • 1.5" Memory Foam Plus
  • 8" Body Shaped Innersprings with reinforced perimeter
  • 0.5" DuraDense Base Foam.
The Simba 5000 Pro Flex is the coolest and most comfortable from Simba's range and is compatible with adjustable beds. The seven layers are:
  • Natural Canadian wool layer
  • Simbatex memory foam infused with graphite for cooling
  • Two layers of conical pocket miQro™ springs. Featuring up to 5,000 springs, made with British Steel, enclosed in a 100% polyester pocket

Comfort Info
Comfort is at the core of the Douglas Alpine’s design. The EcoLight Cooling Gel Foam layer adapts to your body’s contours, providing excellent pressure relief for joints and muscles. This layer also incorporates cooling technology, which dissipates heat and prevents uncomfortable temperature build-up during the night.
Ultra breathable cover and hybrid design increase airflow to keep the mattress cooler. No more sweaty nights.
Sleep like a pro with Simba's most advanced mattress ever. Experience ultimate comfort and airflow from up to 5,000 miQro® springs and unbeatable temperature regulation thanks to the luxurious natural wool top layer.
Support Info
Support is critical for maintaining healthy spinal alignment, and the Douglas Alpine excels in this department. The Elastex Foam provides responsive support that adapts to your body’s weight and sleeping position. Beneath this layer, the Motion-Isolation Support Foam offers a stable base, evenly distributing weight and minimizing sagging over time. This combination of materials ensures that the mattress provides targeted support to key areas like the lower back and hips while reducing pressure points—a common cause of discomfort and pain.
The new Helix Plus has higher density foams to match heavier sleepers and provide increased durability. The coil unit has best in-class edge support, so plus size sleepers never feel like they're falling off the mattress. An extra layer of high density, 4 pound foam is included in one of the three foam layers to help provide maximum support for people with high BMIs.
Even more pocket miQro™ springs mean greater airflow and unbeatable body weight distribution. Plush, lush, gravity-defying comfort. The springs are lighter and finer than traditional chunky bedsprings, so you won't get that poking-in feeling. And they're made to a patented, cone-shaped design which hugs every point of the body and pivots and flexes to distribute your weight fully for pressure relief.
Comfort Specs
The Douglas Alpine mattress is designed with a multi-layered approach to maximize comfort and support. Below is a breakdown of its key specifications: * Thickness: 3 inches of EcoLight™ Cooling Gel Foam. * Features: Enhanced pressure relief and temperature regulation.
Our special latex-foam hybrid alternative, designed to be denser to contour to your body.
Uniquely pressure relieving, we use 4 pound Memory Plus Foam - a special, ultra dense and extra durable Helix blend.
The Canadian wool layer is naturally temperature regulating and a dream for hot sleepers. Whatever the season you can rest cool and rest easy.
The Simbatex foam has an open-cell structure and uses advanced graphite cooling technology to draw heat away from your body, keeping you cool and comfortable.
Patented miQro springs allow air to move freely through the mattress - unlike pure memory foam which traps heat in. The conical design of the springs means they are cone-shaped and allow for greater airflow between the springs.
Support Specs
The Douglas Alpine excels in providing targeted support that alleviates pain and promotes healthy spinal alignment. Its combination of responsive Elastex™ Foam and dense support foam reduces pressure points in key areas such as the lower back, hips, and shoulders, making it an excellent choice for sleepers dealing with chronic discomfort. These layers work together to distribute weight evenly, ensuring long-term durability and consistent support for pain relief and overall comfort. * Thickness: 2 inches of Elastex™ Foam. * Features: Responsive and adaptive support for various sleep positions.
Firm Memory Foam provides ergonomic support and cushioning, the transition layer has a higher IFD to match your body type. Extra support.
Hundreds of individual taller coils designed to cradle and support heavier weight. Reinforced perimeter to provide edge support.
The bottom foam layer of the mattress provides base support and durability to the entire mattress.
Up to 5,000 miQro® springs mean greater airflow and better body weight distribution. These 25mm conical pocket springs are made with 100% British steel, manufactured in Leeds, and are enclosed in a 100% polyester pocket.
Simbatex memory foam moulds expertly to your body shape. It's like a mattress tailor made for you.
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.
A zoned support base provides different levels of support to different areas of your body to reduce pressure points.
Fabric Specs
* Material: Stretch-knit cover made from sustainable, breathable fabric. * Features: Hypoallergenic and machine washable for easy maintenance.
Each Plus mattress comes with our Ultra Breathable Tencel technology designed to increase airflow and to keep you cool.
With an even thicker hypoallergenic knitted cover, Simba have layered on the lux - without compromising airflow. The mattress has four convenient handles (on Queen and King sizes) to allow you to rotate or move your mattress with ease. Whilst the 750gsm cover itself is not removable or washable, the grey base fabric can be cleaned with a soft, damp and clean cloth using small circular motions. Using a mattress protector could help extend the life of your mattress.
