Mattress buying guide

A good night’s sleep is imperative to our physical and psychological well-being, so choosing the right mattress is one of the most important decisions you will make. The Sleep Council advises that a mattress should be changed at least every seven years to maintain the health benefits. In the video below our home expert, Lucy Alexander explains why putting a little thought into getting the right bed and mattress can help you sleep easier.

How to buy a mattress

We all know the importance of catching our 40 winks, so save yourself the sleepless nights and check out our must-read guide to tracking down your perfect mattress!

A bed is nothing without a great mattress – our body repairs and heals while we are sleeping. Interestingly, broken sleep is down to discomfort most of the time, which starts with the mattress.

Ideally you would replace a divan base and a mattress at the same time, but we understand that budgets don’t always stretch that far. The following checks should help you decide if you need a new frame:


Do I need a new bed and mattress?

  • Check the existing base for sagging or out of place springs, squeaking and/or creaking. If you find any of these, you probably need a new base!
  • If your bed has drawers, check to see if they’re damaged, as well as making sure all feet/castors are still there and that the two halves of your bases are connected and lined up.


If you have a bed frame or bedstead

Make sure the frame is sturdy and level and that it doesn’t have any parts missing, such as slats, bolts or other fittings. Ensure all the screws and bolts are tight and that the frame isn’t making any noise when in use.


Did you know?

Did you know that we spend a third of our lives in bed? So, that’s three years and four months you’ll spend on your next mattress… make sure it’s a good one! A great mattress should last for up to 10 years – read our mattress care guide to make sure you’re getting the most out of yours.
