Silentnight Deep Sleep Mattress Topper

The Silentnight Deep Sleep topper is the UK's default answer to a too-firm or past-its-best mattress: a 5cm layer of soft hollowfibre in a quilted cover that sits on top of the mattress and changes how the bed feels for less than the cost of a takeaway for four. With over 24,000 Amazon reviews at 4.4 stars, it is comfortably the most-bought mattress topper in the country. It works in two situations. On a mattress that's too firm, the hollowfibre layer adds genuine plushness at the surface — shoulders and hips sink in rather than pressing flat. On an ageing mattress, it papers over minor dips and tired springs, buying a year or three before replacement becomes unavoidable. Elasticated corner straps hold it to mattresses up to around 30cm deep, and the whole topper is machine washable. Silentnight is Britain's biggest bed manufacturer, and the topper is hypoallergenic and produced to the company's usual safety standards. It compresses with use, as all soft fibre toppers do, and responds well to a regular shake-out. For students, renters, guest beds and anyone not ready to spend £600 on a new mattress, it's the highest-impact £23.50 you can spend on your sleep.
