The Importance of Upgrading to a King Size Bed

Switching to a king size bed is one of the most important decisions you'll make in your life. It gives you more space and comfort, especially if you're an active sleeper or if you're sharing the bed with kids. A king size bed often leads to better sleep quality because it gives you more personal space.

At AHD Furniture we understand the importance of a stable bed frame. Not only does it provide you with the support you need, but it also sets the tone for your bigger room.

Understanding Standard King Size Bed Frame Dimensions

A king size mattress (commonly referred to as an “eastern king”) measures 76 inches wide by 80 inches long, or 38 inches for each sleeper. Knowing the dimensions of your king size bed frame will help you choose a frame that fits both your mattress size and your preferences.

A king size bed frame measures 76.5 inches wide by 78 inches long, or 80.5 inches by 82 inches, depending on the bed frame you choose. King size headboards are slightly wider than king size bed frames, measuring 79 inches wide by 81 inches long, or 48 inches wide by 64 inches high.

Variations of King Size Beds

In addition to standard measurements, king size mattresses come in several variations, each with its unique dimensions. AHD Furniture is here to guide you through these variations:

California King Bed

A California king mattress (also called a Western king) is 72 inches wide and 84 inches long. It’s 4 inches narrower than a standard king, but 4 inches longer. This size is perfect for taller sleepers looking for extra legroom. Make sure your bed frame can handle the extra length. In some cases, you can even use extension panels to extend your existing king size bed frame.

Split King Bed

The split king size mattress allows you to customize the firmness of your mattress to your individual needs. It is made up of two twin XL (38 in wide by 80 in long) mattresses that are side by side to make a standard 76 in by 80 in king mattress. This size is recommended by AHD Furniture for those who want a mattress that is tailored to their comfort and health needs, especially when combined with split adjustable base.

Oversized King Beds Measurements

While California kings are common, AHD Furniture introduces three other king mattress variations that are larger than a standard king:

Bed Size Dimensions (in inches) Dimensions (in centimeters) Mattress Size (approx.) Ideal for Recommended Maximum Height
Texas King 80 inches x 98 inches 203 cm x 249 cm 80 inches x 98 inches Spacious sleeping 6 feet 6 inches (78 inches) or slightly shorter
Alaskan King 108 inches x 108 inches 274 cm x 274 cm 108 inches x 108 inches Large families or groups 9 feet (108 inches) or slightly shorter

Types of King Size Bed Frames

As you embark on your bed frame search, AHD Furniture recommends considering different types of bed frames based on the size of your room and decor preferences:

Panel Frames

Standard and easy to find, panel frames consist of two side panels, a headboard, and a footboard. The foundation is made of wood or metal slats that support the mattress and a foundation if needed.

Platform Frames

Similar to panel frames but with a solid wood or slatted foundation, platform beds do not require an additional foundation to support the mattress. The mattress can be placed directly on the base of the bed frame.

Sleigh Beds

Made of wood, sleigh beds have a headboard and footboard resembling a horse-drawn sleigh. These frames often feature curved or scrolled woodwork and a slatted foundation.

Four Poster Bed Frames

Characterized by four large pillars at each corner, these frames, often made of metal or wood, have a decorative headboard and footboard.

Four Poster Bed Frames

Characterized by four large pillars at each corner, these frames, often made of metal or wood, have a decorative headboard and footboard.

Wyoming King

Similar to four-poster frames but with four additional slats connecting each pillar at the top, creating a square-shaped canopy. Curtains or fabric can hang from the canopy for decorative purposes.

Mattress Foundations and Adjustable Frames

AHD Furniture emphasizes the importance of proper mattress support. Most modern mattresses can be placed directly on the base of the bed frame, eliminating the need for a box spring. However, if additional support is required, consider:

Mattress Foundations

Available in solid or slatted options, mattress foundations can be placed in the center of most bed frames. These bases consist of a wood or metal box upholstered or covered in durable fabric.

Adjustable Frames

Ideal for customized comfort, adjustable bed frames allow sleepers to raise their head and legs during sleep, offering benefits such as reduced snoring and improved circulation.
