Within each of the category names you mention there are three
different mattresses. It will depend on which particular
mattress in each category that you are trying to compare. The
Argos website does quote the firmness ratings for each.
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:
Pick your new mattress on the official Silentnight website
Sleep on it for at least 28 nights as it can take a little time to adjust to a new mattress
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
