  • Why choose a super king size mattress protector from Simba?

    Our mattress protectors do more than one job. This is a further layer of protection that brings a full range of benefits. Our mattress protectors in super king size not only provide an additional layer of comfort, but also extend the life of your mattress. Because even the biggest beds can benefit from a mattress protector.

    Like all products at Simba, our super king mattress protectors have been built upon innovative, performance-led technology. They’ve been designed to help you get the best night’s sleep possible. We want you to sleep well, and wake up feeling refreshed.

    First of all, the materials used. They’re made from super-soft and lightweight 200 thread count cotton. This breathable material allows for optimum airflow around you and your mattress which is key to regulating your body’s temperature at night, so there’s no need to worry about overheating here.

    The quality and sustainability of the materials we use is a high priority. That’s why we’re part of the Better Cotton Initiative (BCI), a not-for-profit organisation which seeks to transform the cotton industry by bettering environmental protections, sustainability measures, and working conditions. Better Cotton is not physically traceable to end products, but BCI farmers benefit from the demand for Better Cotton in equivalent volumes to those we source. This initiative is transforming the cotton industry by improving working conditions, sustainability measures, and environmental protections.

    Additional comfort comes from the 200gm fill that our mattress protectors have, and our super king mattress covers also use Bi-Ome® tech. This targets and eliminates microorganisms that can cause odours. It also reduces the rate at which they grow and multiply. The result is a cleaner, fresher mattress, for a longer period of time.

    When it comes to putting the mattress protector on, we’ve made it easy. Each of our mattress covers have bound edges. Not only do these look good, but they provide a very secure fit. Your Simba mattress protector will stay perfectly in place from the time you go to sleep, to when you wake up.
