How To Choose The Right Mattress Size?
When picking the right mattress, there is more to consider beyond its dimensions and minimum room size. Mattresses directly impact the quality of your sleep and should be considered an investment. Keep these factors in mind when shopping for a new mattress.

Sleeping Partner

One of the most critical factors when picking a mattress size is who you are sharing the bed with. While a full mattress suits most couples, it may not suit couples with children or pets. A king mattress might be best if you share a bed with multiple people.

Height

Most beds are wide enough for at least one person but may not always be long enough. For example, a twin bed might be wide and long enough for an average-height sleeper but certainly won’t be able to accommodate someone over 6’5”.

Room Size

Your bed should leave enough space for the rest of your furniture. As a rule of thumb, you’ll want to leave at least two feet of free space on each side of your bed to ensure you can move around comfortably. Where your room is located can also influence your decision. For instance, moving a king bed can be extremely challenging if your room is on the second floor of your home. Consider door and staircase width, as these factors can also dictate how you maneuver your mattress.

Budget

You should always consider your budget when shopping for a new mattress, but don’t make it your priority. When mattress shopping, what you pay for is what you get. Don’t buy the cheapest one you see – you risk compromising quality and longevity. Mattresses are an investment. Purchasing a high-quality mattress can save you more in the long run, as it can help you avoid premature deterioration.

Get Overall Comfort With The Right Mattress Size
Choosing a mattress can be confusing, especially when facing many options and size. However, you can make the process easier by considering the size of your room, height, budget, and whether you plan to share a bed with someone else. Quality mattresses cost hundreds of dollars and often last more than a decade, so you’ll want to do ample research to ensure you make the right choice!
