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 featuresHow 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.

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.

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.
