(Don’t Sleep On This! for 2026)

Are you throwing away your hard-earned money by not knowing when to buy a mattress at Costco? It’s a question that might keep you up at night, especially if you’re in the market for a new bed. Let’s dive into the world of Costco mattress sales and ensure you get the best deal possible in 2026!

Quick Summary Guide

Section 1: The Importance of Timing in Mattress Purchases

1. The Mattress Market Overview

The mattress market is a fascinating beast.

It’s driven by seasonal trends, consumer behavior, and even economic factors.

You might not think about it much, but people tend to buy mattresses at specific times of the year.

Why is timing so crucial?

Well, it all boils down to supply and demand.

Mattress retailers, including Costco, often offer significant discounts during periods of lower demand or during major sales events to clear out inventory and boost revenue.

For example, did you know that the mattress market is expected to reach $43 billion by 2027?

That’s a lot of mattresses!

With that kind of money on the line, retailers are constantly strategizing to capture your attention (and your wallet).

2. Understanding Sales Cycles

Mattress sales cycles generally revolve around peak shopping periods.

Think holidays, back-to-school season, and those major retail events that everyone circles on their calendar.

• Holidays: Memorial Day, Labor Day, and President’s Day are notorious for mattress sales. Retailers use these long weekends to lure in shoppers with tempting discounts.
  
• Back-to-School: Families often refresh their homes before the school year starts, which includes buying new mattresses for kids or college students.
  
• Black Friday & Cyber Monday: These are the granddaddies of all sales events. You can often find some of the year’s deepest discounts on mattresses during this period.
  

Economic factors also play a role.

When the economy is strong and consumer confidence is high, people are more likely to spend money on big-ticket items like mattresses.

Conversely, during economic downturns, retailers may offer more aggressive discounts to encourage sales.

Section 2: Costco’s Sales Strategy

1. Costco’s Unique Pricing Model

Costco operates on a membership-based model, which significantly affects its pricing strategies.

Because members pay an annual fee, Costco can afford to offer lower markups on its products, including mattresses.

This means you’re often getting a better deal right off the bat compared to traditional retailers.

Inventory turnover is also crucial for Costco.

They need to keep products moving to maximize space and efficiency in their warehouses.

This pressure to clear inventory often leads to sales events and promotions on mattresses.

2. Historical Trends of Mattress Sales at Costco

Let’s get down to brass tacks: when exactly does Costco put mattresses on sale?

Based on historical data, here are some patterns I’ve observed:

• January: New Year’s sales often extend into January, with discounts on mattresses to kick off the year.
  
• February: President’s Day weekend is another prime time for mattress deals at Costco.
  
• May: Memorial Day weekend typically brings significant discounts on a wide range of products, including mattresses.
  
• September: Labor Day weekend is another key sales event, with Costco offering competitive deals on mattresses.
  
• November: Black Friday and Cyber Monday are the big kahunas. Expect some of the year’s best prices on mattresses during this period.
  

For example, in previous years, I’ve seen Costco offer up to $400 off select mattress models during Black Friday.

They’ve also been known to bundle mattresses with bedding sets or offer free delivery and setup.

Section 3: Seasonal Sales Events to Watch For in 2026

1. Key Holidays and Events

Alright, let’s zero in on the specific holidays and events in 2026 where you’re most likely to find mattress sales at Costco.

2. Costco-Specific Promotions

Beyond the major holidays, Costco also runs its own special promotions throughout the year.

Keep an eye out for these:

• Warehouse Clearances: Costco occasionally clears out older inventory to make room for new products. This can be a great opportunity to find heavily discounted mattresses.
  
• Member-Exclusive Discounts: As a Costco member, you’ll often have access to exclusive discounts that aren’t available to the general public. Be sure to check your email and the Costco website regularly for these offers.
  
• Instant Savings: Costco frequently offers “instant savings” on select products, including mattresses. These discounts are automatically applied at checkout.
  

For example, I’ve seen Costco offer $100-$200 off specific mattress brands as an “instant savings” promotion.

These deals can pop up at any time, so it’s essential to stay vigilant.

Section 4: How to Prepare for Mattress Sales at Costco

1. Researching the Right Mattress for You

Before you even think about sales, it’s crucial to figure out what type of mattress you need.

Here’s a quick rundown of the most common types:

• Memory Foam: Known for its contouring and pressure relief. Great for side sleepers and those with joint pain.
  
• Innerspring: Traditional mattresses with coils. Offer good support and bounce.
• Hybrid: Combine the best of both worlds, with coils for support and memory foam or latex for comfort.
  
• Latex: Made from natural or synthetic latex. Durable, breathable, and offers good support.

It’s also a good idea to test out mattresses in-store, if possible.

Lie down on different models and see what feels best for you.

Don’t be shy – this is a significant investment!

And don’t forget to understand Costco’s return policy.

They’re known for their generous return policy, but it’s always good to know the details before you buy.

Once you know what type of mattress you want, it’s time to set a budget.

Consider these factors:

• Mattress Type: Memory foam and hybrid mattresses tend to be more expensive than innerspring models.
  
• Size: A king-size mattress will cost more than a twin-size.
  
• Features: Extra features like cooling technology or adjustable bases can add to the price.
  

Prioritize features that are most important to you.

Do you need excellent edge support?

Are you a hot sleeper who needs a cooling mattress?

Knowing your priorities will help you make the most of your budget.

Frequently Asked Questions

What brands of mattresses does Costco typically carry?

Costco partners with reputable brands like Sealy, Serta, Beautyrest, and their exclusive Kirkland Signature line, offering a range of hybrid, innerspring, memory foam, and latex options. These brands are selected for their durability, comfort, and value, with many featuring cooling technologies, pressure relief, and edge support ideal for various sleep positions such as side, back, or stomach sleeping. Before purchasing, consider your preferred sleep style and any specific needs like motion isolation for couples or lumbar support for back pain relief.

What mattress firmness levels are available at Costco?

Costco mattresses come in plush, medium, firm, and adjustable firmness options to suit different body weights, sleep preferences, and health concerns. Plush models excel for lightweight side sleepers seeking hip and shoulder cushioning, while firm options provide robust support for heavier individuals or stomach sleepers to maintain spinal alignment. Evaluate your body weight—typically under 130 lbs for plush, 130-230 lbs for medium, and over 230 lbs for firm—and test in-store if possible to ensure the level promotes proper posture and minimizes pressure points.

Does Costco offer a sleep trial period for mattresses?

Many Costco mattresses include a generous 365-night sleep trial, allowing you to test the mattress in your home for a full year before deciding on a return. This extended period accounts for body adjustment time, unlike shorter trials elsewhere. Factors to consider include setup time, initial off-gassing for foam models, and consistent sleep tracking to assess comfort, temperature regulation, and support over weeks, ensuring it meets long-term needs for you or your partner.

What warranties come with Costco mattresses?

Costco mattresses typically feature 10- to 25-year limited warranties covering manufacturing defects like sagging over 1.5 inches or foam breakdown, with pro-rated replacements after the full period. Prorated portions mean you pay a percentage based on usage years, so review terms for coverage on coils, foam integrity, and workmanship. Consider your expected longevity needs—longer warranties suit families or those investing in premium models—and register the product promptly to activate full protection.

What is Costco’s return policy for mattresses?

Costco provides a hassle-free 100% satisfaction guarantee with no-restocking fees on mattresses within the sleep trial window, including free returns via white glove service for many models. This policy is more generous than competitors, but note exclusions for hygiene covers removed or damage from improper use. Weigh this against your confidence in the purchase—trial it thoroughly at home, protect with a waterproof cover, and coordinate return pickup to avoid common pitfalls like mismatched sizes or unmet expectations on firmness.

Does Costco provide delivery, setup, and old mattress removal?

Yes, Costco offers white glove delivery for an additional fee, including in-home setup, old mattress haul-away, and packaging removal, ensuring a seamless transition without lifting heavy items. Standard shipping is curbside for online orders. Budget-conscious buyers should factor in room access for king sizes, stair navigation, and disposal fees elsewhere—opt for this service if mobility is limited or to prevent damage during DIY moves, prioritizing convenience alongside total cost.

Are Costco mattresses compatible with adjustable bases?

Most Costco hybrid and foam mattresses are designed for adjustable bases, with flexible constructions that bend without damage, supporting zero-gravity positions for acid reflux or snoring relief. Innerspring models may have limitations, so verify specs for flexibility ratings. Before buying, measure your bed frame compatibility, consider split king options for couples with differing preferences, and ensure warranty coverage extends to powered base use for optimal ergonomic benefits.

What financing options are available for Costco mattress purchases?

Costco provides 0% APR financing through partners like Synchrony for qualified members on purchases over a certain amount, with terms up to 48 months, plus Citi Visa cards for everyday rewards. Avoid high-interest traps by paying off promptly, calculating total costs including delivery, and comparing to personal loans if needed. This flexibility aids bigger investments in split mattresses or bundles with protectors and pillows, aligning payments with budgets while securing quality sleep sooner.
