Frequently asked questions on Mattresses
A mattress usually lasts around 6–8 years, depending on the type, quality and how well it is cared for. You should replace yours sooner if it feels unsupportive, visibly worn, damaged or sagging.
Signs your mattress may need replacing include sinking, sagging, visible wear and tear, stains or odours, worsening allergy symptoms, sore muscles when you wake up, or struggling to get comfortable during sleep.
It’s recommended to clean your mattress around every six months, or more often if you suffer from allergies, have pets, or your mattress is exposed to dirt, spills or stains.
For small stains, spot-clean the area with a small amount of suitable cleaning solution on a clean cloth, then blot rather than soak the mattress. For a fresher mattress, dry baking soda can be sprinkled over the surface, left for a few hours, then removed
A divan bed is a bed made with a matching base and mattress designed to fit perfectly together. Divan bases often include built-in drawer storage, offering easy-access space without needing to lift the mattress.
