More horizontal space = a good night's sleep

Buying a new bed and choosing the best mattress is a huge investment. You spend a third of your life lying on them, so when you need to fork out for a new one, you want to make sure you get the best bed size to ensure a peaceful and uninterrupted night's sleep. But how do you know what to look for?

When you bought your bed, did you choose it based on the best bed size for you and your partner? Or did you just pick one that looked good in your bedroom? Most people would fall into the latter category, as the general expectation is that beds, much like the other furniture in your home, need to look just as good as they feel comfortable.

However, when it comes to buying a bed, size really does matter.

We asked the not-for-profit National Bed Federation (opens in new tab) to give us their top tips for choosing the best bed size for you and your partner to guarantee a good night's sleep. 

1. Size matters

'Buy as big a bed as you can,' says Simon, 'more space equals less partner disturbance, which equals better sleep'.

Simon continues, 'If you do visit a store (when they’re finally open again!) discuss your requirements with the store's expert as they know more about beds than you, and get a shortlist of about three or four beds.'

'If you’re shopping with your partner, lie beside each other on each bed and put your hands behind your head. If your elbows touch each other then there’s not enough space – opt for a bigger bed size. Lie on each bed for at least five to ten minutes, turning over and lying in different positions - don’t just lie like a statue!'

2. Always test a bed using a pillow

'It's also a good idea to take your normal pillow with you,' adds Simon, 'or choose a new pillow whilst you’re in the shop. The  pillow makes a huge difference to keeping your whole spine in the correct position when lying on your back or side.'

3. Do your research, both on and offline

'Ask friends and relatives for their personal recommendations and experiences with different products and retailers websites. Don’t rush into buying – take your time. Make a list of what your key requirements are, for example, pressure relief, allergies, ease of use, such as a no-turn mattress.'
