Double Mattresses

Double mattresses are the most popular standard mattress size measuring 135 cm (4 feet 6 inches) wide and 190 cm (6 feet 3 inches) long - a great choice for two adults if you have limited space in your bedroom. From memory foam and pocket sprung to orthopaedic and medium-firm mattresses, we have the right double mattress for you.

60 night comfort exchange

Our comfort exchange gives you 60 nights to get really comfortable before making a decision. If you're still not loving your new mattress within 60 nights from delivery, you can exchange it for another mattress. It's as simple as that.

Here's how it works:

  1. Pick your new mattress on the official Silentnight website
  2. Sleep on it for at least 28 nights as it can take a little time to adjust to a new mattress
  3. If you're not happy after the initial 28 nights you can exchange it for a new mattress, as long as you claim within 60 nights of delivery
