Bed Sizes & Mattress Sizes in the UK

It's important when bed or mattress shopping that you buy a bed appropriately sized to you. Of course, if bedroom floor space is not a limited resource then you may be tempted to buy the biggest bed you can get for your money and there's nothing wrong with that. You can always go bigger, if you prefer a bigger bed and have the space for it in your bedroom. However, there is such thing as too small a bed. With this guide, we hope to prevent people from making the big mistake of buying a bed that's too small for them!
