King Size Mattresses at Ashley
When you’re shopping for a king-size mattress, talk with the experts at Ashley! We carry a wide selection of king mattresses to suit different sleeping positions and needs. Whether you want the added comfort of a pillow top, firmness to support your neck and spine, or hypoallergenic materials, we have the brands and styles to grant you a restful night’s sleep.King Mattress Dimensions
A king mattress size is typically 76 inches wide and 80 inches long (at least in the United States). The thickness can vary from 8 to 14 inches, depending on the features and manufacturer. A king mattress fits best in a large room, so it doesn’t appear cramped.California king mattresses are a slightly longer option if you or your partner is taller than average or if you prefer more legroom. These measure 72 inches wide by 84 inches long, so they’re slightly narrower than the standard king mattress size.
If the narrower measurement concerns you, look for a split California king mattress, which is 76 inches wide. Much like placing two twin XL mattresses side by side, a split mattress provides varying firmness on each side of the bed — a compromise for couples with varying preferences and positions. The added width also reduces the likelihood of feeling the other person toss or turn during the night.
What Brands Offer King Mattresses?
All major mattress manufacturers carry king mattresses. At Ashley, you’ll find top-name brands such as Sealy mattresses, along with Purple Mattress, Beautyrest, Stearns & Foster, Tempur-Pedic, GhostBed, Chime, Scott Living by Restonic, Serta, and our own rigorously tested Ashley Sleep line.We’re proud to offer such a variety so customers can find a mattress they want within their budget. The average price of a king-size mattress varies depending on materials and features. A memory foam mattress that provides good support and pressure relief can cost as low as about $400. A hybrid mattress that combines innerspring coils with memory foam to relieve pressure points with a breathable feel might run about $1,000 to $1,400. A luxury king mattress, such as one with high-quality materials, more coil layers for bounce and support, and other features, can cost more than $2,000.
While the price might give some people pause, consider that the average life of a king-size mattress is about seven to 10 years. Latex and high-density memory foams or polyfoam mattresses tend to last the longest while traditional innerspring beds last roughly five to six years. Some brands offer a 10-year warranty on material and manufacturing defects, while others have a trial period of 30 nights or more to test whether your new mattress inspires sweet dreams.
