Choosing the mattress size that is right for you is just as important as choosing your mattress comfort level and construction type and considering your sleeping position.
Your current needs, living space and sleeping arrangement will influence your decision between choosing a Full over a Queen bed, while consideration of your future plans may affect whether you choose a King-sized bed versus a Queen size one.
No matter your situation we know that one size definitely doesn’t fit all when it comes to a bed, so take some time and consider the information below as your own personal comfort and mattress sizes guide that is here to help you find your perfect fit.

Do you have a young adult living at home with you? Do you have a growing child you don’t want to buy multiple beds for throughout the years? Do you have a guest room?

WHY YOU SHOULD CHOOSE A QUEEN SIZE
Approx. Size & Dimensions: 60” X 79.5” / 4,770 sq in / 33.1 sq ft
Are you a single sleeper who likes to spread out or roll around while sleeping? Are you on a budget?

If you answered yes to any of these questions the most popular mattress size (queen) is what you should be looking at.

Do you like more room to spread out while you are sleeping? Do you love your significant other but crave your space in bed? Are you sharing the bed with a partner who is a hot or restless sleeper? Do you share a bed with someone on a different sleep schedule than you? Or are you a human or fur parent who sometimes shares their bed whether they really want to or not?

Are you 6’2″ or taller? Do your feet hang off the end of your current bed? Do you have a long, narrow master bedroom/sleep space? Do you crave more leg room in the middle of the night? Do you like to sleep with a lot of pillows and find yourself towards the end of the bed at night? Do you have fur babies that like to sleep at the foot of your bed? If you nodded a yes to any of these questions and are looking for a long, narrow sleeping solution with enough room to still spread out on, a California King might be the solution you are looking for.

There is no right or wrong answer to the age old question, “What mattress size is best for me?” A new place to sleep is an investment you won’t want to replace in a few years so make sure you take your time, write out a pros and cons list if you have to, and don’t forget to consider the future along with your current situation. Good luck! You’ve got this!
