It limits motion transfer to a large extent, helping light sleepers fall asleep easily.

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.

Sleeping Position:

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.

Budget:

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.
