King Size Mattress FAQ

King size mattresses represent the pinnacle of sleeping luxury and space, but they're not right for every situation or bedroom. Whether you're curious about dimensions, cost, or the logistics of getting one home, we've covered the essential information to guide your decision.

What size is a king size mattress?

The standard king size mattress dimensions are 76 by 80 inches, providing the widest sleeping surface available in standard mattress sizes. This size fits best in master bedrooms that are at least 12x12 feet to allow proper room proportion and furniture placement. Ashley manufactures king size mattresses to these exact specifications with various firmness levels and sleep technologies.

What are the measurements of a king size mattress?

A king size mattress measures exactly 76 by 80 inches, making it 16 inches wider than a queen while maintaining the same 80-inch length. These measurements make king mattresses ideal for couples who want maximum sleeping space or families who occasionally share the bed. Ashley designs their king size mattresses to these specifications with various sleep technologies and comfort features

How wide is a king size mattress?

King size mattresses are 76 inches wide, offering the most spacious sleeping surface available in standard mattress sizes for home use. This width ensures couples have plenty of personal space while maintaining the intimacy of sharing one bed together. Ashley offers king size mattresses including hybrid mattress options in this standard 76-inch width with various support systems and comfort technologies for better sleep quality.

How much is a king size mattress?

King size mattress prices generally range from 600 USD for basic models to 1,600 USD for premium options with advanced comfort technologies and materials. The price depends on construction like memory foam, innerspring coils, or hybrid mattress design along with brand reputation and warranty coverage. Ashley offers competitive pricing on their king size mattress selection with clear information about features and value.

How much does a king size mattress weigh?

King size mattresses typically range from 600 USD to 1,800 USD depending on the materials, construction type, and comfort features you choose for your bedroom. Budget-friendly innerspring models start around 600 USD while premium memory foam and hybrid mattress options can cost 1,200 USD to 1,800 USD for quality construction. Ashley offers king size mattresses across this price range with financing options to help make comfortable sleep more affordable.

How to move a king size mattress?

Use heavy-duty moving straps and a furniture dolly when possible to help support the weight and make maneuvering easier through your home. King mattresses should never be folded or bent, especially memory foam and hybrid models, as this can permanently damage internal components. To avoid these challenges, consider Ashley's professional delivery, which ensures your mattress arrives safely and is properly positioned.

How to transport a king size mattress?

Rent a moving truck or large van if you don't own a vehicle capable of transporting a king mattress without compromising its integrity. Use multiple tie-down straps to secure the mattress and prevent movement that could cause damage during transit or create safety hazards. Ashley's delivery team uses specialized equipment and vehicles designed specifically for safe mattress transportation to your home.

How to get rid of a king size mattress?

You can donate your quality king mattress to local charities or shelters if it's in good condition, though you'll need to call ahead to confirm they accept donations and arrange pickup. Other options include selling through online marketplaces like Facebook or Craigslist, or taking it to mattress recycling centers that break down materials for reuse. When you purchase a new mattress from Ashley, their delivery team can conveniently remove your old one during the same visit.
