If you’re wondering where to buy a king size mattress, you’re in the right place. This guide will walk you through all your options, from online retailers to local stores, to help you find the perfect fit for your needs and budget.
Choosing a king mattress is a big decision. It’s a major investment in your sleep and health. With so many places to shop, it can feel overwhelming. But don’t worry. We’ll break down the pros and cons of each shopping avenue, giving you the clear information you need to shop with confidence.
Where To Buy King Size Mattress
You have more choices than ever before. The main paths are buying online or in a physical store. Each has its own advantages, and the best choice depends on what you value most: convenience, hands-on testing, price, or service.
1. Online Mattress Brands (Bed-in-a-Box)
This is a hugely popular modern option. Companies ship your mattress compressed in a box directly to your door.
- Major Brands: Casper, Nectar, Purple, Saatva, Tuft & Needle.
- How it Works: Order online, the mattress arrives in a box, you unroll it, and it expands.
- Key Advantage: Exceptional convenience and lengthy sleep trials (often 100 nights or more).
- Consideration: You can’t try it before you buy, relying on reviews and return policies.
2. Major Retail & Department Stores
These are classic, one-stop-shop destinations where you can see and feel many brands at once.
- Examples: Mattress Firm, Macy’s, Raymour & Flanigan, Ashley HomeStore.
- How it Works: Visit a showroom, test models on the floor, and work with a sales associate.
- Key Advantage: Ability to physically test comfort and firmness. Immediate availability and in-person negotiation.
- Consideration: Prices can be higher, and sales pressure is common.
3. Warehouse Clubs & Big-Box Stores
These stores offer value, often featuring well-known brands at competitive prices.
- Examples: Costco, Sam’s Club, Walmart, Target.
- How it Works: Both in-warehouse selection and online catalogs. Membership may be required for some.
- Key Advantage: Strong value pricing, generous return policies (especially Costco), and bundle deals.
- Consideration: Selection may be limited compared to specialty stores, and testing options can be minimal in-store.
4. Direct from Manufacturer or Specialty Stores
For high-end or specific mattress types, going straight to the source is a great idea.
- Examples: Tempur-Pedic stores, Sleep Number stores, local organic latex or natural bedding makers.
- How it Works: You visit a branded store or a factory showroom dedicated to that specific type of product.
- Key Advantage: Deep expertise on the product, highest quality materials, and often the best pricing for that specific brand.
- Consideration: Can be more expensive and options are limited to that brand’s lineup.
5. Furniture Stores
Many furniture retailers also have a robust mattress department, making it easy to coordinate your bedroom set.
This is a convinient option if your buying a new bed frame at the same time. You can ensure everything fits and matches stylistically.
6. Online Marketplaces
Platforms like Amazon and Wayfair host countless mattress sellers and brands.
- Key Advantage: Vast selection, competitive pricing, fast shipping (especially with Prime), and easy-to-read customer reviews.
- Consideration: Quality varies wildly. Be sure to research the specific brand, not just the marketplace. Return logistics can be more complicated.
Key Factors to Compare Before You Buy
No matter where you shop, keep this checklist in mind. It will help you compare apples to apples.
Sleep Trial & Return Policy
This is crucial, especially online. Understand the length of the trial, any fees for returns (like shipping or pickup), and the process. A 100-night trial is standard for online brands.
Warranty Coverage
Look for a minimum 10-year warranty. Read what it covers (like sagging over a certain depth) and what it excludes (stains, normal wear). A longer warranty often indicates better durability.
Delivery & Setup Options
Does the price include white-glove delivery? This means they bring it in, set it up, and remove your old mattress. Or is it curbside drop-off? Factor this cost and effort into your decision.
Price & Hidden Fees
Look beyond the sticker price. Check for sales tax, delivery fees, and any setup charges. Online prices often include everything, while stores may add fees.
Sales & Discount Times
Mattresses go on sale during major holidays. The best times to buy are around Memorial Day, Fourth of July, Labor Day, Black Friday, and New Year’s.
A Step-by-Step Guide to Making Your Purchase
Follow these steps to make a smart, stress-free decision.
Step 1: Determine Your Budget
Set a realistic range. King mattresses can range from $500 to over $3,000. Remember, this is a long-term investment in your sleep quality.
Step 2: Identify Your Needs
Think about your sleep style, any pain points (back, shoulder), if you sleep hot, and if you share the bed with a partner. This will guide you toward the right material (innerspring, memory foam, latex, hybrid).
Step 3: Research Online First
Read reviews on multiple sites, watch video reviews, and narrow down to 2-3 brands or models that fit your criteria. Don’t skip this research phase.
Step 4: Test In-Store (If Possible)
If you’re considering a model sold in stores, go test it. Lie down in your typical sleep position for at least 10-15 minutes per mattress. Wear comfortable clothes.
Step 5: Check Final Details
Before clicking “buy” or signing an order, double-check the trial period, warranty, delivery details, and the final all-in price. Make sure your room is ready for the new mattress arrival.
Common Pitfalls to Avoid
- Firmness Confusion: Firmness is personal. A “medium” from one brand can feel like a “soft” from another. Rely on your own comfort, not just the label.
- Ignoring the Foundation: Your new mattress needs proper support. Check if it requires a specific base or if your old box spring is still suitable.
- Impulse Buying on Sale: A sale is great, but don’t buy a mattress that doesn’t meet your needs just because it’s cheap. The deal won’t matter if you can’t sleep on it.
- Not Reading the Fine Print: The devil’s in the details with trials and warranties. Know the return process inside and out before commiting.
FAQ Section
Where is the cheapest place to buy a king size mattress?
Warehouse clubs like Costco and online marketplaces like Amazon often have the lowest base prices. Also, look for clearance sales at major retailers. But remember, the cheapest option isn’t always the best value if it compromises on comfort or durability.
What is the best website to buy a king mattress?
There’s no single “best” site. It depends on the brand you want. For bed-in-a-box brands, buy directly from their website (Casper.com, etc.) for the best trial terms. For comparison shopping, Amazon and Wayfair are excellent. Always check the return policy of the specific seller.
Can I buy a king mattress in store and have it delivered same day?
Sometimes, but it’s not guaranteed. Many larger mattress stores have same-day delivery if you purchase early and if the model is in their local warehouse. You must always ask about availability and delivery schedules before purchasing.
Is it better to buy a mattress online or in-store?
Online offers better convenience, longer sleep trials, and often better prices. In-store allows for hands-on testing and immediate takeaway. For many, a hybrid approach works best: research online, test specific models in-store if available, then compare prices and policies before buying from the channel that offers the best overall package.
What should I do with my old king mattress when I buy a new one?
Many retailers offer old mattress removal as part of a white-glove delivery service (sometimes for an extra fee). You can also donate it if it’s in good condition, or contact your local waste management for bulk pickup guidelines. Plan this ahead of time.
Finding the right place to buy your king size mattress ultimately comes down to your personal priorities. If you value ease and a risk-free trial, an online brand is a fantastic choice. If you need to feel the support and firmness for yourself, a trip to a showroom is essential.
Take your time, use the steps in this guide, and don’t rush the process. A good mattress lasts for years, so investing the effort now to find the perfect one is worth it. With the right information, you can navigate the market confidently and find the ideal king size mattress for countless nights of better sleep.
