Mattress manufacturers say eight years. The Better Sleep Council recommends every seven to ten years. But how often should you really replace your mattress? The truth is, a number of factors are involved.

Here, we look into the tell-tale signs it’s time to ditch the old and bring in the new.
The variables

A variety of aspects come into changing your mattress, the first being the type. Innerspring mattresses, for example, which can be used on a regular or double day bed, can last up to ten years. Good quality memory foam ones, however, can last up to 15 years with the right care and regular rotation. On the other end of the scale, hybrid mattresses often need to be replaced every six years.

Other, more personal factors come into play too, including your body size, whether you sleep with a partner or alone, and how you sleep. To maximise the lifespan of your mattress, however, clean and rotate your mattress regularly, keep pets off the bed, and air it occasionally by removing the sheets and covers.

When it’s time to change

The primary sign that it’s time for a change is a decline in your sleep quality. A lumpy, saggy mattress will cause your sleep to suffer, leaving you feeling drained during the day. The upper part of a mattress comprises layers that support your body and relieve pressure. When these begin to deteriorate, you may experience aches and pains where the support is failing. If you’re finding you wake with stiffness or soreness, or that your sleep is worse than normal, it may be time to change your mattress.

Experiencing worse allergies can indicate a need to change your mattress too. Over time, dust mites can get into your mattress, and their faeces - which contain a protein that causes allergic reactions or irritates asthma symptoms – can build up. While vacuuming or steaming the area can help, an increase in allergies out of season may mean a new mattress is required.

How to choose a good mattress

There’s no hard and fast rule to choosing the perfect mattress. Whether you’re sleeping on a single, a double or a day bed, there are some key points to be aware of. For example, if you experience shoulder pain, a firm mattress won’t cushion you enough and may lead to you waking in the night from the pain. Conversely, if you have hypermobile joints, a soft mattress won’t provide enough support.

If you get hot easily, it may be wise to avoid memory foam. This is because the dense structure of foam means there’s nowhere for heat to escape – so springs are a better option. Finally, just trying a mattress can give you an idea of how it feels to you. If you’re unsure when you test it, find other options rather than assuming it’ll be fine. A small niggle can be a big hassle after a few months.
