Why choose a king single mattress?

When buying a mattress for a solitary sleeper, a large two-person mattress can seem like a waste of space in your bedroom. But that doesn’t mean you need to totally forego the comfort of a generously sized mattress. A king single is the perfect combination of luxurious size and pragmatic compactness.

And speaking of perfect combinations, our mattress combines a pocket spring system with the comfort of a king single memory foam mattress to give you a sublime night’s sleep. It’s supportive and comfortable, all at the same time.

Trial the mattress for 100 nights

You can’t really know if you love a mattress until you’ve slept on it. That’s why we offer a 100 Night Guarantee. If you don’t love it, we’ll take it away and give you a full refund.

Quality comfort

Our hybrid mattresses have all the support of pocket springs, and all the comfort of memory foam. It’s the technology that has won us back to back Bedbuyer awards for most outstanding overall mattress in a box in 2020 and 2021.

CertiPUR-US certified foam

Some foams are better for you — and for the environment — than others. We use high-class foam, that has a low level of Volatile Organic Compounds (VOCs). This is foam without the toxic chemicals and ozone depleters.

What our customers have to say

Frequently Asked Questions

Yes! We believe that everybody deserves to sleep on a mattress that they love. If you decide that our mattress just isn’t for you within 100 nights, we will happily donate it to a local charity and refund you the full amount of the mattress.

If you live within reach of one of our partnered charities, they’ll even pick the mattress up for free. If you’d like to find out more about the 100 Night Guarantee, get in contact with our team.

In addition to memory foam, there are several other materials that go towards making the best king single mattress in a box.

  • Dynamic edge support: Sick of mattresses that sag? Our edge support preserves the structural integrity of your mattress.
  • 3D spacer fabric: Side panels which provide airflow and ensure that you don’t get too hot during the summer nights.
  • Cashmere knitted fabric: Soft, luxurious cashmere, because you deserve a pristine level of comfort.
  • Gel infused memory foam: NASA-level technology that’s great for your joints and contours to your body.
  • Natural latex: Riddled with ventilation holes, this chemical-free latex really lets the mattress breathe.
  • High definition pocket springs: These put the spring into king single pocket spring mattress. With our spring system, you’re sure of a comfortable and well supported sleep.

Just open the box, take off the protective layer, roll out your mattress and, hey presto, you’ve got a beautiful new sleeping solution.

Any sturdy bed base will serve you well. We recommend a flat base, rather than a springy surface like a spring bed base, for optimum mattress performance.
