How Long Do Mattresses Last?

Each type of mattress and its unique construction influences its lifespan. The most common types are memory foam, spring, gel and latex. Memory foam and latex mattresses are known for their durability but multiple factors - such as hygiene (breakfast in bed being a common culprit!), changing sheets regularly and the addition of a mattress topper or protector - contribute to their longevity. Generally, a good quality mattress should last between seven and ten years, but some could surpass this period.

How To Choose The Right Mattress

You might be thinking, "What is the most comfortable mattress?" But the real question is, "What is the most comfortable mattress for me?" Everyone sleeps differently, meaning there's no 'one size fits all' method to mattress shopping. Instead, think about whether you prefer plush comfort or firm support, require hypoallergenic materials or suffer from health issues like back pain. Mattresses aren't as aesthetically pleasing to shop for like bedroom chairs or storage, but we recommend test-napping before you buy your next mattress, which adds a fun factor!
