Expert review

If you're looking for a memory foam mattress that moulds to the shape of your body, you might want to consider the Ergoflex 5G. It's only available online, but you can get a full refund if you don't like it after sleeping on it for 30 nights. But mattresses can be comfortable without being supportive for your spine, so you should read our full mattress review before you order one.

What's included:
  • Pros and cons
  • What is it?
  • What's it like to lie on?
  • Is there anything I should watch out for?
  • Should I buy it?
