Let’s break down the process. A king size mattress is a significant investment in your comfort and health. Knowing where to look—and what to look for—can save you time, money, and a lot of frustration.

Where Can I Buy A King Size Mattress

You can purchase a king mattress from a wide variety of places, each with its own advantages. The main categories are online mattress brands, traditional brick-and-mortar stores, department stores, warehouse clubs, and even furniture stores. Your choice will depend on how you prefer to shop, your budget, and your need for hands-on testing.

1. Online Mattress Brands (Bed-in-a-Box)

This is one of the most popular ways to buy a mattress today. Companies ship your mattress compressed in a box directly to your door.

  • Major Brands: Casper, Purple, Nectar, Saatva, Leesa, Tuft & Needle.
  • How it Works: You order online, the mattress arrives in a box, you unroll it, and it expands to full size.
  • Key Advantages:
    • Huge convenience and direct delivery.
    • Long risk-free trial periods (often 100 nights or more).
    • Competitive pricing due to the direct-to-consumer model.
    • Warranties are typically lengthy.
  • Things to Consider:
    • You can’t try it before you buy (though trials mitigate this).
    • You need space to unbox it and time for it to fully expand.
    • Returns usually require donation or pickup coordination.

2. Traditional Mattress Stores

These are dedicated stores focused solely on mattresses and sleep products.

  • Major Chains: Mattress Firm, Sleep Number, Original Mattress Factory.
  • How it Works: You visit the store, test mattresses with a sales associate, and arrange for delivery.
  • Key Advantages:
    • Ability to physically lie down on multiple models.
    • Expert advice from (though sometimes commissioned) sales staff.
    • Immediate availability or quick delivery from local warehouses.
    • Often have floor models or clearance items for sale.
  • Things to Consider:
    • Sales pressure can be a factor.
    • Prices may be higher due to overhead costs.
    • Store selection is limited to the brands they carry.

3. Department Stores

Large department stores often have extensive home sections.

  • Examples: Macy’s, JCPenney, Bloomingdale’s.
  • Key Advantages:
    • Opportunity to test mattresses while shopping for other home goods.
    • Frequent sales, holiday promotions, and coupon opportunities.
    • Well-known, trusted brands like Sealy, Serta, and Simmons.
  • Things to Consider:
    • Selection might be smaller than a dedicated mattress store.
    • Sales staff may be less specialized in sleep products.

4. Warehouse Clubs

Membership-based retailers known for bulk buys and value.

  • Examples: Costco, Sam’s Club, BJ’s Wholesale Club.
  • Key Advantages:
    • Excellent value and competitive pricing, often with bundles.
    • Generous return policies (Costco is famously lenient).
    • You can sometimes find high-quality name brands at a discount.
  • Things to Consider:
    • You need a paid membership to shop.
    • Inventory can be inconsistent—what you see today might be gone tomorrow.
    • Testing options are usually limited to a few display models.

5. Furniture Stores

Stores that sell entire room setups often include mattresses.

  • Examples: IKEA, Ashley HomeStore, Raymour & Flanigan.
  • Key Advantages:
    • Convenient if you’re also shopping for a bed frame or bedroom set.
    • IKEA offers unique sizing and modern, affordable options.
    • Can often package deals for delivery.
  • Things to Consider:
    • Mattresses may not be their primary specialty.
    • The focus might be more on the furniture than on sleep technology.

6. Direct from Manufacturer

Some established brands sell straight to the public.

  • Examples: Tempur-Pedic (through their own stores or website), Stearns & Foster.
  • Key Advantages:
    • Full access to a brand’s entire product line.
    • Potential for factory-direct promotions or discounts.
    • Specialized knowledge about the specific brand.

Key Steps Before You Buy Anywhere

Don’t just jump at the first sale you see. Follow these steps to ensure you get the right mattress.

Step 1: Determine Your Budget

King mattresses range from under $500 to over $5,000. Set a realistic range. Remember, this is a long-term purchase for your health. A good target for a quality king is often between $1,000 and $2,500, but excellent options exist at both ends of the spectrum.

Step 2: Know Your Size (It’s Not Just “King”)

There are actually two main king sizes in the US:

  • Standard King (Eastern King): 76 inches wide x 80 inches long. The most common choice.
  • California King: 72 inches wide x 84 inches long. Narrower but longer, ideal for taller individuals.

Make sure you measure your room and your bed frame before deciding. An Alaskan King or other specialty sizes require different retailers altogether.

Step 3: Identify Your Preferred Mattress Type

This affects feel, price, and where you might shop.

  • Memory Foam: Contours to the body, excellent pressure relief. Often found online and in most stores.
  • Innerspring: Traditional bouncy feel with coil support systems. Ubiquitous.
  • Hybrid: Combines coils with foam or latex layers for balanced comfort. Very popular in mid-to-high-end markets.
  • Latex: Responsive, buoyant, and often cooling. Sold by specialists and some online brands.
  • Airbed: Adjustable firmness on each side (e.g., Sleep Number). Sold in their own stores and some department stores.

Step 4: Research and Read Reviews

Once you have a type and budget, research specific models. Use independent review sites, not just testimonials on the brand’s own website. Look for patterns in reviews—if dozens of people say a mattress sleeps hot, it probably does.

Step 5: Test If Possible

If buying in-person, test properly. Wear comfortable clothes. Lie down in your usual sleep position for at least 10-15 minutes per mattress. Don’t feel rushed. Bring your partner if you share the bed.

Step 6: Understand the Fine Print

This is crucial for both online and in-store purchases.

  • Trial Period: What is the length? Are there any fees for returns?
  • Warranty: What does it cover (sagging, defects)? What is the process for a claim?
  • Delivery & Setup: Is it free? Do they bring it to your room? Do they remove the old mattress?
  • Return Policy: Is it a full refund? Do they arrange pickup, or do you have to donate it?

How to Get the Best Deal

Timing and negotiation can save you hundreds.

  • Shop Holidays: Major holidays (Memorial Day, 4th of July, Labor Day, Black Friday) offer the best sales.
  • Negotiate in Stores: In brick-and-mortar stores, the price is often not fixed. Ask if it’s the best price or if they can include free accessories (pillows, sheets, a bed frame).
  • Check for Price Matching: Many retailers will match a competitor’s advertised price.
  • Look for Clearance: Floor models, discontinued lines, or returned items can be deeply discounted.
  • Consider the Bundle: Sometimes buying a mattress, frame, and protector together gets you a better overall package deal.

Common Pitfalls to Avoid

  • Ignoring Return Policies: A great price means nothing if you’re stuck with a mattress you hate.
  • Buying Based on Name Alone: A well-known brand doesn’t guarantee it’s the right mattress for your body.
  • Assuming Higher Price = Better Quality: While often true, the mattress-in-a-box revolution has created high-quality options at lower prices due to their business model.
  • Forgetting About the Foundation: Ensure your current bed frame or base is compatible with your new mattress type (e.g., some foam mattresses require a solid or slatted foundation with minimal gap).

FAQ Section

Where is the cheapest place to buy a king size mattress?

Warehouse clubs (Costco, Sam’s Club) and online brands during sales often offer the best value for the quality. IKEA is also a source for very budget-friendly king mattresses. Always balance price with return policy and quality.

Can I buy a good king mattress on Amazon?

Yes, Amazon sells many reputable bed-in-a-box brands and has its own lines. The advantage is fast shipping and Amazon’s return process. The disadvantage is you cannot test it first, so rely heavily on reviews and product details.

What should I do with my old mattress when I buy a new one?

Many delivery services offer old mattress removal for a small fee (often $50-$150). This is the easiest option. You can also donate it if it’s in good condition, or contact your local waste management for bulk pickup rules. Some charities will even pick it up for free.

Is it better to buy a mattress online or in-store?

It depends on your preferences. Online is great for convenience, long trials, and value. In-store is essential if you need to physically test a mattress before committing and want immediate, expert guidance. Many people now research online and then test finalists in person.

How long does it take to get a king mattress delivered?

Online brands typically ship within 1-5 business days, with delivery a few days after that. Traditional stores may offer next-day delivery if the model is in stock, or it could take 2-6 weeks for a special order. Always ask for an estimated delivery timeline before paying.

What’s the difference between a king and a California king?

A standard king is wider (76″ vs. 72″) while a California king is longer (84″ vs. 80″). The Cal King provides more leg room for tall people, but the standard king gives more width for couples or families with pets/kids. Sheet sizes are different and not interchangeable.
