Is a Bigger Bed Really Better?
Do you really NEED a king-size mattress/bed? After all, they take up more space and cost more than their queen- or full-size counterparts. King bedding is more expensive too. But for many there are some definite advantages, including the following:
- More room for couples. Did you know that a full-size mattress only gives each partner two feet of ‘personal space’ which is less than a baby has in a crib!
- More room to move. Very few people stay dead still for seven to eight hours when they sleep. A bigger mattress means more room to move without falling out of bed!
- We are all getting bigger. According to a study published in the New England Journal of Medicine over the past 50 years people across North America have got larger and taller, so therefore, most people need a bigger bed!
- Going up a size is not as expensive as people think, with the average difference in price between queen and king-size mattresses being under $50.
