A new mattress will certainly take up the most of your time when purchasing a new bed. But if you don’t have a robust bed frame, your new mattress may not perform or endure as long as it should.

Mattresses are supported by bed frames. Bed frame sizes are normally the same as the dimensions of the accompanying mattress, even if the exact measures differ by an inch or two. As a result, bed builders use the same nomenclature for mattress sizes to describe bed frames.

For your convenience, we’ll cover the most typical bed frame measurements, unique instances, and the various types of bed frames now on the market.

Bed Frame Height

In most cases, the height of a bed frame is between 12 and 16 inches. For the average adult, this is the ideal height. Most adults can sit on the edge of their bed with their feet firmly on the ground and their knees bent, thanks to a conventional mattress height of 10 to 15 inches. To make getting in and out of the bed a little less cumbersome, consider raising the bed’s height.

Be aware that bed frame height might vary greatly based on the style and purpose for which it is being used. Some modern bed frames are fairly low to the ground, while others are rather tall. These beds may not be suited for the elderly or people with mobility concerns because of their height.

Many alternative bed frame heights can be found outside the norm. Toddler and young kid bed frames are often lower to the ground and may contain guard rails for the safety of your child. The height of different parts of the bed can be adjusted using adjustable bed frames.

Specialty Bed Frame Sizes

The six typical mattress sizes are normally accommodated by bed frame dimensions. For bespoke or gigantic mattresses, such as the Alaskan King or the Family Size, there are various caveats.

Additionally, bunk beds and loft beds are instances of speciality bed frames, in which two or more beds are stacked on top of one other. Additionally, trundle beds allow users to hide away the mattress while they are not in use, just as Murphy beds. Aside from being built to carry standard-sized mattresses, these speciality bed frames can also be used as a piece of furniture because of their unique design.

What Is a Bed Frame?

You can think of a bed frame as the part of your bed that holds the mattress and foundation. It is also known as a bed frame, which raises your mattress off the ground.

A bed frame consists of four legs and a rectangular structure to hold the mattress and bed foundation. In other cases, the mattress is supported by a separate foundation that can be nested inside the frame. A headboard, footboard or footer, and posts may also be included in more elaborate bed frames.

It is common for children’s or hospital beds to include higher guard rails on the side of the bed frame, as well. The use of adjustable bed frames is also on the rise. A multi-hinged bed foundation with an electronic control allows you to adjust the angle of support for your bed using this bed frame style.

Consider foundations, which have a flat surface and are not supported by slats; and box springs, which have springs inside. Despite the fact that foundations provide a more stable platform for the mattress, they tend to be less breathable. In contrast to other mattress types, box springs were originally developed to supplement innerspring mattresses and aren’t required in most cases.

Benefits of Using a Bed Frame

A bed frame’s primary tasks include supporting the mattress, increasing airflow, and raising the bed to a comfortable height.

It is easy for a mattress to sag if it is not placed on a flat, firm foundation. The purpose of a bed frame is to keep a mattress from becoming deformed or sagging with the weight of the person sleeping on it. As a matter of fact, many mattress manufacturers will refuse to honor a manufacturer’s warranty if you don’t utilize an appropriate bed frame.

Because it raises your mattress off the floor and rests on a pair of slats, a bed frame aids in better ventilation for your mattress as a whole. Additionally, this inhibits the formation of mold and germs, and keeps the mattress from coming into contact with dirt and dust.

In order to make a statement, many people choose a bed frame that enhances the design and feel of the space. Under-bed storage can also be achieved with the help of a sturdy bed frame.


Types of Bed Frames

It’s fascinating to see how designers have experimented with the basic framework of a bed over time. We’ll take a look at some of the most prevalent bed frame styles.

In a panel bed, the headboard and footboard are joined by two side panels that form the frame. Panel bed frames, which are often built of wood, are known for their sturdiness. Box spring foundations are commonly used with panel beds.

An integrated slatted wood, solid wood, or metal platform in a platform bed frame avoids the need for a separate base to support the structure of the bed. Headboards and footboards are optional on platform beds.

The sleigh bed frame became popular in the United States and Europe in the 19th century. This bed frame style has a curving headboard and footboard and sometimes raised edges on the side panels to mimic a sleigh or sled. Modern sleigh beds may be made of metal or leatherette instead of wood, and its curves and flourishes may be less pronounced.

As the name suggests, a 4-poster bed has four tall posts, or columns, at each of the bed’s four corners. Posts can also be used only for decoration in specific situations. In many cases, four-post bed frames have a tester, which is a rectangular upper support structure. This can be used to put up a canopy or drapes to keep you warm at night and provide you some privacy.

Two bed frames are placed on top of one another, with a staircase leading up to the upper sleeping area. However, it isn’t uncommon to see three-bed bunks in high-density settings like dormitories, military barracks or even hostels. Children love bunk beds, and they’re a fantastic option for anyone who has a restricted amount of floor space, but they’re typically only available in twin sizes.

A loft bed, like a bunk bed, has a raised bed frame. A loft bed frame, on the other hand, does not include a second bed. The space beneath the lofted bed can be utilized for a variety of purposes, including the establishment of a study or lounge area or the storage of household goods. A loft bed is an effective way to make the most of a tiny room’s limited floor area if you just need to sleep one person.

An additional mattress can be stored beneath your primary mattress using a trundle bed frame, which has a rolling platform. For individuals who wish to welcome visitors but don’t have the space for a separate guest room, this is a perfect option.

There are built-in storage compartments underneath a mattress in a storage bed frame. It’s a good option for people who don’t have a lot of extra space in their bedroom or closet. There are numerous variations on the theme of storage beds. The captain’s bed, which has a set of drawers underneath the mattress on either side of the frame, is a common type of storage bed. An Ottoman bed features a concealed compartment beneath the mattress that can be accessed by raising the bed.

Common Bed Frame Materials

It is essential that your bed’s foundation be supported by a solid bed frame. The majority of bed frames are constructed from solid and long-lasting materials like wood or metal.

Solid wood beds are the most common, however plywood or fiberboard can be used in some low-cost variants. birch is the least expensive of the solid wood options, with oak and pine being the most common.

Wood-based bed frames are often more robust and less likely to wobble or squeak under strain because of their hefty component sections. Wooden beds, on the other hand, tend to be heavier because of their thick and solid design.

Metal is a long-lasting, reasonably sturdy material that is frequently less expensive than solid wood in its construction. Metal bed frames are also lighter and easier to maintain than wood ones. Metal bed frames can be made in a variety of forms, from futuristic and industrial to more traditional, using alloys such as brass or steel.

Bed frames can also be upholstered, which means that padding and textiles are used to cover them, giving them a unique appearance and feel. For people who desire a headboard with a softer surface or prefer the look of a covered bed frame, upholstered bed frames may be a good option. If you’re looking for an easy-to-clean bed frame, upholstered ones are not the best option.

What is the standard bed frame height?

In general, the bed frame height spans from eight to eighteen inches for most people. If the frame has replaceable legs, the height is determined by the brand, model, and type of frame. In addition to reducing dust exposure, raising the mattress off the floor can provide additional storage space.

Should the bed frame be bigger than the mattress?

When purchasing a new bed frame, be sure that it is the same size as the mattress. A queen-sized bed, for example, needs a queen-sized frame to sit on. Buying a bed frame that is too big for your mattress can cause the mattress to move around. In contrast, if you buy a bed frame that is too small for your mattress, you risk damaging both the bed and the frame.

Can a twin bed fit two adults?

Even if two adults can fit in a twin bed without falling out, it won’t be cozy. Sleeping area for each person will be approximately 18 inches. This is sufficient for some people to comfortably rest on their sides, but not much more. For couples, we don’t recommend a mattress smaller than a queen.

Can a king bed fit in a 12 x 12 room?

A normal king mattress can be accommodated in a room as long as it is at least 12 feet by 12 feet in size. If the room’s dimensions are enough, there should still be plenty of room for additional bedroom furniture such as nightstands and lamps. It’s also a good idea to leave some room on the floor for movement.

Is a double and full the same size?

The term “double bed” refers to a mattress of the full-sized variety. Despite the name, a double bed is only suitable for one person. A crib-sized mattress has approximately the same amount of sleeping area as a 27-inch-wide mattress for two people to share.


You can’t go wrong with a bed frame in your bedroom. They add a fashionable aspect to the space while also raising your mattress off the floor. In order to have the most support and comfort, make sure your bed frame matches the size of your mattress, whether it is old or new.
