Not necessarily. Just because a mattress is more expensive does not guarantee its comfort to you. Remember, each person has a different preference when it comes to sleeping position, thickness, and firmness of the mattress. So, before investing your money, it is important for you to understand your own requirements. However, an expensive mattress does feature better build quality and more sleeping technologies built into it. Most importantly, an expensive mattress does come with better support from the manufacturer in terms of warranty and trials.
