Over your lifetime, your sleeping needs change. Because of this, you may find that you need to alter your sleeping environment. When choosing a mattress, you should consider who you are buying it for. For example, babies will need specific cot mattresses, smaller in size than adult mattresses. We also stock a range of mattresses that cater specifically to children. Adults may require smaller or larger-sized mattresses depending on their height, weight and build, comfort preferences, and whether they sleep with a partner. We offer a range of adjustable mattresses and beds for those who may find getting in and out of bed a little difficult. We stock a range of mattress sizes, from a small single size, right up to super king size, and a wide variety of sizes in-between! Taking into consideration who the mattress is intended for will enable you to buy a mattress best suited to their needs. 3. How much space do you have? It is important to take into account the size of both your room and bed frame when choosing a mattress, as this can impact what size mattress you choose. Be sure to check what size bed frame you currently have, or would like. An equivalent size mattress should fit the bed frame. It is always a good idea to measure the exact dimensions of your bed frame and check this against the dimensions of the mattress you would like to buy, to be certain. Thinking about the size of your room is important too. Would a larger bed better suit your bedroom? Or do you only have room for a smaller-sized bed? Bed frames can sometimes be a little bigger than mattresses, whereas a divan bed base will have the same dimensions as the equivalent size mattress. Want your bed to take centre stage? As one of the key features of your bedroom, taking into consideration how much space you have available for your bed is important! An explanation of the different mattress sizes Below, we outline who the most popular mattress and bed sizes are most suitable for. What size is a single bed and mattress?

They\’re a great investment for your children and teens, offering years of quality sleep. What size is a double bed and mattress? The most popular bed size in the UK, the standard double bed, is a great fit for two adults. At 4\’6\” x 6\’3\” (135cm x 190cm), a bed and double mattress will fit well into a standard bedroom without overcrowding. They\’re also ideal for visitors if you have a spacious guest room, or if you want to give a little more space to a teenager.
