Hence, always have room dimensions in mind before buying your mattress. A wrong choice can make your room look too small or empty.

Body Weight and Height

Even though a medium to firm mattress is recommended for everybody. Still, know your weight and height well to understand its compatibility with your mattress. If you wake up with aches and a sore body then its time to consult your orthopedic doctor and choose the right mattress.

Sleeping Position:

Your sleeping position and your mattress size go hand in hand. If you are a combination sleeper then huge mattresses are an ideal choice for you, if you like to snuggle then compact mattress sizes are an excellent choice.

Budget

Always know your budget before purchasing a mattress. The bigger the size, the kind of materials used, brand standing- all of the put together decide on the pricing of the mattress. If all of these are good quality and known then the mattress would be on the expensive side.
