5 Best firm mattress for heavy person uk in the UK 2023

If you weigh more than 220 lbs, you may have a hard time finding a comfortable and supportive mattress. Most mattresses are not designed to accommodate larger bodies, and they can sag, sink, or lose their shape over time. Moreover, the heavier you are, the more firmness you need to keep your spine aligned and prevent pressure points. However, firm mattresses designed for heavier people are usually far more expensive than average ones, and they can be difficult to compare and choose from. That’s why my team of sleep experts have done the research for you. We have handpicked and tested dozens of mattresses that claim to be suitable for heavy sleepers, and we have compiled the list of the best firm mattresse for heavy person in the UK after analysing firmness, material type, sleep trial and value for the money.
