For the highest standards of quality and safety
The Salus Sequoia 12000 Pocket Hybrid Box Top Mattress exudes ultimate luxury with its pressure-relieving, refreshing Gelflex foam comfort layer and sumptuous 42cm depth - our deepest mattress!
12000 springs
Providing a supportive core, the Salus Sequoia mattress includes a high 12000 spring count. A layer of 1000 springs are encased in individual fabric pockets which allows them to move independently. This means they can adapt to your movements to provide tailored full body support. The reactivity of the springs encourages better spinal alignment to ease aches.
11000 mini pocket springs provide additional bounce and cuddly comfort for a truly indulgent and luxurious sleep space. The mini springs promote air flow through the mattress. This reduces trapped heat and moisture to limit a build up of mould, mildew and odours.
Cooler comfort
Innovative Gelflex memory foam layer adds to the sumptuous 42cm depth of the mattress. The layer shapes around your body contours to lift weight off your pressure points. Letting your body experience rejuvenating pressure relief and comfort.
Formed with small cooling particles, this foam layer behaves like a gel to dispel excess heat and moisture. Delivering a wonderfully fresh feel that is cooler than standard memory foam and doesn't compromise on comfort.
Enhancing the freshness of the mattress further are the border air vents that increase airflow through the mattress. Topping off the mattress is a wool quilted finish that offers softness and greater breathability, helping the foam in delivering a cooler, fresher feel.
Extra comfort
This mattress features a box top layer which creates a cosy and cushioned sleep space. Transporting you to a world of relaxation and providing ultimate comfort night after night.
Maximised sleep space
High density foam is placed around the border of the spring unit to enhance its stability. This foam encapsulation also increases the durability of the mattress edge. Promoting a firmer feel that does not sink under pressure. So you can sit at the edge of your mattress when getting dressed and enjoy a maximised sleep space at night without a 'roll off' feel. Perfect if you share the bed with a partner so you can both stretch out undisturbed.
Softer feel
This mattress features a soft to medium firmness rating to deliver a comforting feel. Ideal for lighter and smaller stature sleepers. This is because it welcomes your body with soft comfort whilst the medium properties keep you from sinking in and losing support.
Easy care
The single-sided design makes it simple and easy to keep your mattress in good condition. Rotate it head to toe seasonally using the turning handles provided. This encourages even wear across the mattress to reduce and limit the build up of stains, odours and dips. So you can enjoy the brand new feel of your mattress for longer.
Made in the UK
This mattress has been made in the UK and held to strict safety standards to deliver nothing but the highest quality. The 10 Year Guarantee offers ultimate reassurance as you are protected against any manufacturing faults for years to come!
This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.
