About the product

What's a king size mattress topper?

A king size mattress topper is an additional layer used to boost the comfort of an existing mattress (though you won't need it for the Simba Hybrid® Mattress!). The Simba Hybrid® king size mattress topper is the same length and width as a UK king size mattress - just slimmer. The dimensions are 150cm x 200cm x 7cm.

Why choose a king size mattress topper?

If you've invested in the extra space afforded by a king size bed, you're definitely a comfort seeker. But if your mattress still doesn't feel quite right - and changing it isn't on the cards right now - you can still use a double mattress topper for an instant upgrade.

What kind of king size mattress toppers are available?

Latex king size mattress topper: A natural material that tends to be a bit firmer than memory foam, durable, and good for reducing motion transfer. On the downside, it can be sweaty, and some people are allergic to latex.

Memory foam king size mattress topper: Memory foam is adaptable and tends to be budget-friendly, but it can make you feel like you're sinking in too much and tends to get hot.

Fibre fill king size mattress topper: Not dissimilar to putting a thick duvet onto the bed, these are budget friendly and tend to be hypoallergenic. But they don't offer much support.

Foam and springs king size mattress topper: Springs are not easy to find in a king size mattress topper, but are a great way to balance support and comfort and upgrade a mattress.

What's special about the Simba Hybrid® King Size Mattress Topper?

It's hard enough to find a king size mattress topper that offers the comfort of foam with the support of springs. Not only have we done that, we've used the same specially shaped, 100% British steel springs that we put into our Hybrid® Mattress. They move individually in their pockets, and the cone-shape helps them flex in all directions to offer fantastic weight distribution and pressure relief for the shoulders, spine and hips. Plus there's none of the clunky bounciness you get with old-fashioned, traditional springs. And there's a layer of our unique Simbatex air-flow foam, which combines comfort with cooling. Thought we couldn't beat our Hybrid® Mattress? We didn't, we just topped it.
