  • Some factors to consider before selecting the size and dimension of your future mattress include:

Choosing the right mattress size involves considering various factors to ensure a comfortable sleep experience. Here are key considerations:

1. Bedroom Size: Assess the dimensions of your bedroom to determine the appropriate mattress size that fits well without overcrowding the space. To have plenty of space to move around your room and avoid feeling cramped, we recommend approximately inches of space around each side of your bed and bed frame.

2. Individual Characteristics: Consider your height and weight as personal factors that influence the choice of mattress size. This ensures that the mattress provides ample space and support for a restful night's sleep. Your sleep preferences should play a role in your decision-making too.

If you are a back sleeper:
Because you put the most pressure on your lower back, the best mattress for you are medium to firm mattresses. If a mattress is too soft, the torso may sink in more deeply, creating strain.

If you are a side sleeper:
A softer mattress is ideal for a side sleeper, as a too-firm may exert more pressure on your shoulder.

If you are a stomach sleeper:
Sleeping on your stomach may put unnecessary strain on the neck and back, which can be exacerbated by a mattress that does not give adequate support. The answer usually is somewhere in the middle. You might want to choose a responsive firm, medium mattress, or hybrid mattress.

If you are a combination sleeper:
Choose a mattress based on the position you sleep the most in, or a medium firm mattress that’s responsive to facilitate easy movement on the bed.

No matter how you sleep, look for a mattress that offers support and comfort.

3. Sleeping Arrangements: Determine whether you sleep alone or with a partner (or pet!). For couples, it's essential to select a mattress size that accommodates both individuals comfortably. Depending on how much space you have, a Queen, King, or California King beds are typically ideal.
