Size of the Bed Room:
The size of your bedroom is crucial when choosing a mattress. Trying to fit a King size mattress in a small room would make the space look cramped up and would not leave any room for extra furniture. A twin-size mattress in a master bedroom would make your space look empty. Hence, choose your mattress size as per your room size and not just have a comfortable sleep but also make your room look aesthetically beautiful.
Body Weight and Height:
A medium firm or firm mattress is perfect for all body weight. If you wake up with body aches or sore muscles then kindly consult your Orthopedic or Chiropractor before buying a new mattress.
Your and your partner’s sleeping position needs to be considered before you buy a mattress. A wider mattress like King or California King mattress would be ideal if you like to have personal sleeping space or stretch out. Whereas a Queen mattress would be an excellent choice for those who like to cuddle and sleep.
The rule of the thumb is that the bigger the mattress, the more expensive it will be. However, this can change depending on the brand, the material, and its technology.
