Double bed dimensions are 138 centimeters by 188 centimeters and 28 centimeters wider in dimensions. At 188 centimeters, this mattress size is the same length as a single size bed and maybe too short for some adults. However, the extra width gives solo sleepers room to stretch out. Sharing this mattress size with a partner would be difficult, as each sleeper gets just 69 centimeters of individual space – less than a single size bed.
At 138 centimeters wide, a double size mattress is best for a solo sleeper. Two people may find it comfortable for a short period of time, but it would be cramped and difficult to sleep in certain positions. That’s why this mattress size is ideal for older children and guests. Children and teenagers grow quickly, and parents can choose a double bed over a single bed to prevent replacing mattresses for a significant time. Guests may also be more comfortable on a double mattress since it gives more room to sit, organise, and move
