You spend up to 16 years of your life in bed, so a good mattress is a serious investment. Before you head to the shop to start testing, get to know your options with our buyer's guide to mattresses.
- A bed should be 10cm longer than the tallest person who will be sleeping in it, so a king-size is the minimum for someone 6ft or more, and wide enough to allow both partners to lie side by side, hands behind heads, without elbows touching.
- To check if a mattress is supporting you properly, lie down and slide a hand beneath the small of your back. If your hand fits easily, it's too soft; not at all, and it's too firm.
- The base will affect how the mattress feels. A sprung divan will make a mattress seem softer than a solid divan or slatted base.
- Sprung and pocket mattresses are padded with fillings including cotton, lambswool and mohair. Luxurious options, such as cashmere and silk, will mean the finished product is more expensive.
- ‘Orthopaedic' is a term that describes mattresses with a firmer spring. While some swear by them, it's more important to choose a mattress that gives proper support as opposed to just being very hard.
