How Much Does a King Mattress Cost? | Real Price Range

A king mattress typically costs between $900 and $2,500, with most quality models landing in the $1,500–$2,500 range.

King prices feel all over the map — budget options sit near $329 while premium builds top $12,000. That spread looks chaotic until you understand what separates a $500 king from a $5,000 one. Here’s the honest picture of what a king mattress costs and what actually moves the price.

What’s the Typical Price Range for a King Mattress?

The most defensible answer for a U.S. shopper: plan on spending $900 to $2,500 for a king that will serve you well. Quality options cluster between $1,500 and $2,500, according to the Sleep Foundation’s king mattress guide. Here’s how the range breaks down:

• Budget kings: $300–$800 — basic foam or innerspring models from IKEA and Ashley. IKEA U.S. lists kings at $329 to $799.
• Mid-range kings: $800–$2,500 — the sweet spot for most shoppers. Amerisleep’s AS1 king lists at $1,649, and Nectar Luxe Hybrid 5.1 king runs $1,799.
• Premium kings: $2,500–$5,000 — hybrid builds, cooling layers, and brand names. Spring Air Copper Plush Euro-Top Hybrid king lists at $3,599.
• Luxury kings: $5,000+ — adjustable, smart, or high-end specialty beds. Sleep Number’s premium kings reach $12,999.

How Does a King Compare to a Queen in Price?

For the same brand and model family, expect a king to cost $200 to $500 more than the queen version — roughly 15–25% more. That buys 16 inches of extra width (76 x 80 inches versus 60 x 80 inches), a meaningful upgrade for couples but only worth the premium if your bedroom can comfortably fit the larger footprint.

Why Do King Mattress Prices Vary So Much?

Materials and construction drive most of the difference. A $329 IKEA king uses basic foam; a $4,099 Tempur-Pedic king uses proprietary pressure-relieving material with a multi-layer build. Beyond materials, these factors move the price:

• Construction type: Innerspring beds cost less than hybrids, which cost less than all-foam or latex builds.
• Brand positioning: Established names like Tempur-Pedic and Sleep Number price kings at a premium.
• Features: Cooling gels, zoned support, adjustable bases, and smart capabilities each add cost.
• Durability: Higher-priced kings often use denser foams and stronger coils that hold up longer — a $500 king that sags in three years costs more per year than a $1,800 king that lasts a decade.

Promotional timing matters too. IKEA prices some kings with windows like “valid while supply lasts,” and retailer discounts can shift the same model’s price by hundreds of dollars. Always check the current listing before budgeting.

Where Should You Buy a King Mattress?

Most major U.S. retailers carry king sizes. Rooms To Go, Macy’s, Ashley, Costco, Target, and Mattress Firm all stock kings, with prices spanning from a few hundred dollars to over $5,000 in a single store’s catalog. For price-conscious shoppers, our tested roundup of the best budget king mattresses covers models that deliver solid comfort without the premium markup.

Before checkout, verify dimensions (76 x 80 inches for standard king) against your bed frame and confirm foundation and sheet compatibility. Also, don’t confuse standard king with California king — they’re different sizes, and comparing prices across sizes will mislead you.

For quality reference, Wirecutter’s mattress testing consistently emphasizes that a good mattress doesn’t need to cost thousands — but skimping too hard often means replacing the bed sooner. A $1,500–$2,500 king from a reputable manufacturer typically offers the best balance of comfort, durability, and value for most sleepers.
