A cozy bedroom, Do Beds Need a Box Spring? [Here's Which Ones Do]

How A Box Spring Helps Your Mattress

Box springs support your mattress. They keep your bed level so you can sleep evenly, increase the life of your mattress, and may be required in the mattress’ warranty.  The coils in the box spring match the coils in your mattress.  This coil system allows for airflow to keep your bed cool.

Foam and latex mattresses cannot be used on box springs because the coils will damage the mattress by causing it to sag. Using a box spring with foam and latex mattresses will nullify most warranties for these types of beds.

Is it OK to Put a Box Spring on Floor?

It is okay to put a box spring on the floor.  When doing this, you may want to put a non-slip covering under the box spring, so it does not slide on the floor.  A box spring on the floor will not allow the air to flow through, and it also may collect allergens, such as dust.  In some climates, mold, which is very toxic when inhaled, can grow around and on the box spring on the floor.  Mold is a known cause of many illnesses, so you may consider this when deciding whether to put your box spring on the floor.

Can you use a piece of plywood instead of a box spring?

Yes, you can use a piece of plywood the size of your mattress instead of a box spring.  Be sure to check your mattress warranty, though.  If the warranty requires a box spring, using plywood as your base will void your mattress warranty.

Are platform beds better than box springs?

The answer to this question is a personal preference.  Platform beds are not as tall as the box spring beds.  They are usually five to seven inches tall.  If you can comfortably get in and out of bed lower than the traditional box spring style, then you may prefer the platform bed.  Platform beds can be a space saver in the room, more contemporary in design, and less expensive because you only need one mattress.  The platform bed is potentially firmer than you prefer.  So, trying out platform versus box spring beds is advised before purchasing one.

Do I need a box spring if I have slats?

Platform beds do not require a box spring.  The platform of the bed acts as the support for the mattress—slats make-up the platform, which curve upward and are two to four inches apart.  The upward curve gives spring to the bed, and the space between the slats allows air to flow to the mattress to keep it cool. 

Can you put a mattress directly on slats?

The mattress for a platform bed is placed directly on the slats of the bed.

Can you still use a box spring on a platform bed?

While box springs are not necessary for platform beds, they can be used on the bed if you would like the height of the bed to be higher.  It may also make the platform bed a bit softer.

Is it Bad to Put a Mattress Directly on Floor?

Placing a mattress on the floor may void your mattress warranty if it requires your mattress to be on a box spring or platform.  It is not bad to put your mattress on the floor as long as it does not affect the mattress warranty.  It will be affected by the same problems foundations experience when placed on the floor and cause difficulties getting up from the mattress if you are not very agile.
