“If your mattress is no longer providing the comfort and support you need for a good night's sleep, it’s time to replace it,” says Tristine Hargreaves, executive director at Bed Advice UK and The National Bed Federation. An ageing mattress doesn’t just lose its feel-good factor; it can show clear signs of decline, from sagging to lumps, and may leave you waking with aches and pains. Hargreaves recommends replacing your mattress every seven to 10 years, noting that stretching beyond this window often results in a tangible drop in both comfort and support.
If yours has reached that point, we found the Simba hybrid luxe mattress to be the best mattress overall. Over several months (and sometimes years), we’ve tested dozens of mattresses in real homes, cutting through the noise to identify those that genuinely deliver. Our mattress testers ranged from 20 to 65, with varying body types and sleep styles. Each mattress was trialled for a minimum of one month (but often years) to build an accurate picture of how it performed over time. Our final edit spans a range of firmness levels, materials and price points.
