The Casper UK single mattress: Award-winning comfort
The perfect single mattress for your bedroom
Need a mattress for a compact bedroom that gives you space to sprawl and stretch in? Casper’s UK single mattress is 90 x 190 cm (or 3’0 x 6'3), 24 cm high, and weighs 19 kg. The single bed mattress is spacious enough, but shorter than a Casper EU single.
Why the Casper Single Mattress?
We carefully select only the highest-quality foams as the basis of the Casper mattresses. We want to make sure that our mattress not only cradles your body but supports you exactly where you need it.
The Casper relieves strain on your spine – no matter your body size, preferred sleeping position, or if you’re a light sleeper or deep sleeper. Casper’s innovative layered structure makes for the perfect level of firmness and softness.
You’ll find countless different types of single memory foam mattresses, varying in materials, firmness levels and zone layouts. Finding the ideal combination while trying to work through all of the technical jargon is no easy feat.
That’s why we chose to make the decision easier for you: We developed a mattress that suits around 80% of the population, straight out of the box. A mattress of unmatched quality that moulds to your body whilst keeping you cool throughout the night.
