After years of research and development Simba has created a unique industry first purer foam, Simba-Pure. Foam in other mattresses includes old ingredients to meet fire safety regulations. These old chemicals include TCPP, phosphate, parabens, biocides and persistent organic pollutants.
These old chemicals are safe for you, but harmful to the planet. Simba-Pure, is free from those pollutants and still exceeds fire safety regulations.

About the Product
A super king size mattress measures 180cm x 200cm x 25cm, making it 30cm (or a foot) wider than a standard UK king size. In old money, it's 6 feet wide.
In many retailers, a super king size mattress is the largest size available (we have one more!). Similar to a US king size, these offer the luxury of incredible space for couples - like having a standard UK single each - with plenty of room for kids and pets to clamber in for lazy Sunday morning snuggles. They need plenty of clearance space, but the area under the bed can be used to keep clutter out of sight, depending on the height and style of the base. If you're lucky enough to have a sizeable bedroom, or can move wardrobes and drawers into a separate dressing space, they're well worth the investment in dreamy comfort.
Traditional spring super king size mattress: Usually found in guest bedrooms as an economical option, the springs in these old fashioned coil mattresses are joined to each other. So there's plenty of support, but the bouncing can get a bit much (if it's not creaking too).
Pocket spring super king size mattress: Pocket spring mattresses offer more flexible support by placing each spring individually into a fabric pocket. These mattresses often still use bigger, cylindrical box springs, with all the pros and cons those offer.
Memory foam super king size mattress: Memory foam is a type of viscoelastic which moulds to the body, making memory foam mattresses very comfortable. However, they're also known for trapping heat and can go softer as they warm up, giving sleepers a sweaty, sinking feeling.
Latex super king size mattress: Latex mattresses are made with latex foam, which is considered a natural product. Bouncier than memory foam, latex is not as good at preventing motion transfer, and tends to be heavier and more expensive.
Hybrid super king size mattress: Hybrid mattresses bring together two different kinds of traditional design, such as springs and foam. This aims to combine the advantages of both, without the limitations - so you get comfort and support without overheating or bouncing around.
As an innovative, unique hybrid mattress, the Simba Hybrid® super king size mattress offers the same award-winning comfort at every size. Our British steel micro springs are smaller and lighter than traditional clunky box springs, which means that there's no see-saw effect when sharing a bed. They're also specially shaped using a patented design to move individually around the hips, spine and shoulders, providing hundreds of points of pressure relief. The Simba Hybrid® super king size mattress has a spring count of 3,000 conical pocket springs, more than some traditional super king size mattresses, matched to a thick layer of visco memory foam for cloud-like comfort.
The Simba Hybrid® Mattress also has a unique comfort layer made of open cell foam which, combined with the air flow offered by the spring layer and breathable sleep surface, makes for altogether cooler, more chilled out nights.
