Key benefits

Key Benefits of the Simba Hybrid Essential King Size Mattress

  • Room to sleep apart, together: At 75cm each for two people sharing, you can turn over or stretch out without negotiating for space at 3am.
  • Less disturbance on different schedules: The 1500 miQro pocket springs move independently, which means an early alarm on one side transfers less across to the other.
  • Extra length for taller sleepers: At 200cm long, the UK king suits anyone approaching six foot whose feet currently hang off a standard-length mattress.
  • Easier to handle than deeper kings: The 20cm profile keeps this UK king lighter to rotate than most hybrids at this width, useful if you do it alone.
  • Cooler with two aboard: Two sleepers generate more heat than one, and the breathable Simbatex foam layer helps that warmth escape rather than build up.

Who should buy the Simba Hybrid Essential King Size Mattress?

This size suits you if...

You share the bed every night and a double has started to feel like a negotiation, one of you keeps earlier hours than the other, or you or your partner are tall enough to want the 200cm length. It also suits couples in pregnancy and the months after, when propping pillows and shifting position takes up more of the bed than usual.

Consider another size if...

Your bedroom falls short of the 2.7m x 2.9m we suggest as a minimum for a king, which is common in newer builds once wardrobes go in. We'd recommend the UK double instead, which keeps the same medium firm feel in a smaller footprint.

FAQ's

Frequently Asked Questions About the UK King

Is the Simba Hybrid Essential UK king good for couples?

Yes, and it's the size we'd point most couples towards. At 150 x 200cm you get 75cm each for two people sharing, and the 1500 pocket springs limit how much of your partner's movement reaches your side. Lightweight side sleepers may find the medium firm feel slightly too firm, though, whatever the size.

Is the UK king long enough for someone over six foot?

The UK king is 200cm long, or 5ft x 6ft 6in overall, so most people over six foot will fit with room to spare. If length is your main reason for upgrading, the UK king delivers it; the UK double and smaller sizes in this range are shorter as well as narrower.

Does the Simba Hybrid Essential come in a super king?

No. The UK king is the largest size Simba makes in the Hybrid Essential, and it's 30cm narrower than the UK super king. If you want super king width you'd need a different mattress; within this model, the UK king is the most space you can buy.

What room size do I need for the Simba Hybrid Essential in a UK king?

We suggest a minimum of 2.7m x 2.9m, with around 3.2m x 3.2m feeling comfortable. That allows walking space on both sides and room for bedside tables. Measure with wardrobes and drawers in place, because a new build master bedroom can shrink quickly once the furniture goes in.

Is the UK king Simba Hybrid Essential hard to move upstairs?

Simba doesn't publish a weight for this size, but the 20cm depth makes it slimmer and lighter to manoeuvre than most hybrid kings. A 150cm-wide mattress is still a two-person job on stairs, so have someone on the other end. Rotating it once it's in place is manageable alone.
