What’s Costco’s Return Policy for Mattresses?

Costco offers a generous return policy for mattresses, allowing members to return most mattresses at any time if unsatisfied, with a few exceptions. Unlike many retailers that impose strict time limits, Costco provides flexibility, ensuring customer satisfaction.

However, policies may vary slightly depending on the mattress type (memory foam, hybrid, or innerspring) and whether it was purchased online or in-store. In this comprehensive guide, we’ll break down Costco’s mattress return process, eligibility criteria, refund methods, and key considerations to ensure a smooth experience.

Best Mattresses Available at Costco

If you’re considering purchasing a mattress from Costco, here are three top-rated options that combine comfort, durability, and value—perfect for different sleep preferences.

Tempur-Pedic TEMPUR-Adapt Medium Hybrid Mattress

The TEMPUR-Adapt Medium Hybrid combines memory foam and coils for balanced support and pressure relief. Ideal for side and back sleepers, its cooling cover and motion isolation make it a great choice for couples. Costco often offers this model at a competitive price.

Sealy Posturepedic Plus Ridge Crest II Plush Mattress

The Sealy Ridge Crest II Plush (Model: RRCRST2P) features reinforced edge support and responsive coils for a plush yet supportive feel. Its breathable fabric and durable construction make it a long-lasting option for those who prefer a softer sleep surface.

Novaform 14″ ComfortGrande Plus Gel Memory Foam Mattress

Costco’s exclusive Novaform ComfortGrande Plus offers premium cooling gel memory foam at an affordable price. With a medium-firm feel and CertiPUR-US® certification, it’s perfect for hot sleepers seeking pressure relief without sacrificing support.

Costco’s Mattress Return Policy: Key Details

Costco’s return policy for mattresses is designed to prioritize customer satisfaction, but there are important nuances to understand before initiating a return. Unlike many retailers that enforce strict time limits (such as 30 or 100 days), Costco generally allows returns at any time for mattresses, provided they are in resalable condition.

However, exceptions apply for certain products, and the process differs slightly between online and in-store purchases.

Timeframe for Returns

Most mattresses purchased at Costco can be returned indefinitely, meaning there’s no hard deadline. This applies to memory foam, hybrid, and innerspring mattresses sold under Costco’s standard return policy. For example, if you buy a Novaform ComfortGrande mattress and realize a year later that it’s too firm, you can still return it—a rare benefit in the retail industry.

Condition Requirements

The mattress must be in like-new, resalable condition to qualify for a full refund. Costco may reject returns if:

• There are stains, odors, or physical damage (e.g., pet hair, spills, or tears).
• The original packaging is missing (critical for online returns, as mattresses are often vacuum-sealed).
• The product shows signs of prolonged use (e.g., visible sagging or indentations).

For instance, a Tempur-Pedic mattress with a removable cover must be returned with the cover intact and unwashed to avoid rejection.

Exceptions to the Policy

Some mattresses fall under special return rules:

1. Third-party vendor items: Mattresses sold by external vendors (e.g., through Costco Next) may follow the vendor’s return policy instead.
2. Final sale items: Clearance or discounted mattresses occasionally marked “non-returnable.”
3. Custom orders: Adjustable bases or split mattresses may have restrictions.

Always check the product page or receipt for fine print. For example, the Stearns & Foster Reserve collection, when sold through a third party, might require returns within 30 days.

Online vs. In-Store Return Process

Online purchases typically require contacting Costco.com for a return shipping label, and the mattress must be repackaged in its original box—a challenge for compressed foam mattresses. In-store returns are simpler: Bring the mattress (and original receipt) to the returns desk. Pro tip: Call your local warehouse first, as some locations may arrange pickup for bulky items.

How to Successfully Return a Mattress to Costco: Step-by-Step Guide

Returning a mattress to Costco requires careful preparation to ensure a smooth process. While their policy is customer-friendly, following proper procedures will help avoid delays or rejections.

Pre-Return Preparation

Before initiating your return, take these essential preparatory steps:

• Inspect your mattress thoroughly: Check for any stains, odors, or damage that might disqualify it from being “resalable.” Even minor coffee spills or pet hair could void your return eligibility.
• Locate all original materials: This includes the mattress cover, tags, and especially the original packaging for online purchases. Memory foam mattresses typically come vacuum-sealed in plastic – you’ll need this intact for online returns.
• Gather purchase documentation: While Costco can often look up purchases using your membership, having your receipt or order confirmation speeds up the process.

Online Return Process (Step-by-Step)

1. Contact Costco.com: Call their customer service (1-800-955-2292) or initiate a return through your online account. Provide your order number and reason for return.
2. Repackage the mattress: This is the most challenging step. The mattress must be compressed back into its original packaging. Professional tip: Use ratchet straps to gradually compress the mattress before sliding it into the plastic sleeve.
3. Schedule pickup: Costco will arrange for FedEx or another carrier to collect the packaged mattress. Note that some rural areas may require you to drop it at a shipping center.

In-Store Return Process

For warehouse returns:

1. Call ahead: Some locations prefer advance notice for large item returns. Ask about assistance with loading if needed.
2. Transport the mattress: Ensure it’s protected during transport. Use a mattress bag or plastic wrap to prevent dirt accumulation en route.
3. Visit the returns desk: Bring your membership card and receipt. The staff will inspect the mattress before processing your refund.

Special Considerations

For adjustable bases or mattress bundles, you may need to return all components together. Some customers report success returning just the mattress from a bundle, but policy technically requires returning the complete set. If you’re returning a mattress after long-term use (6+ months), be prepared for more thorough inspection of wear and tear.

Costco Mattress Return Policy Compared to Major Competitors

Understanding how Costco’s mattress return policy stacks up against other retailers helps consumers make informed purchasing decisions.

Timeframe Comparison Across Retailers

Condition Requirements Analysis

Costco’s “resalable condition” requirement differs significantly from competitors’ policies:

• Most retailers allow some signs of use during trial periods (e.g., Tempur-Pedic accepts returns with minor compression)
• Online brands like Casper and Nectar typically require only 30 days of use before accepting returns
• Warehouse clubs like Sam’s Club have similar policies to Costco but often enforce stricter 90-day limits for mattresses

Hidden Costs and Considerations

While Costco’s policy appears generous, consumers should understand these nuances:

1. Restocking fees: Unlike some competitors (0% at Costco vs. 15-20% at some furniture stores)
2. Return shipping: Online returns may require original packaging (difficult for expanded memory foam)
3. Membership requirements: Only Costco members can utilize the return policy

Expert Recommendations

Based on this comparison:

• For risk-averse buyers: Costco provides the most flexible long-term option
• For online shoppers: Brands with free pickup (like Saatva) may offer easier returns
• For quick decisions: Retailers with shorter trial periods encourage faster evaluation

Maximizing Your Mattress Trial Period: Expert Strategies

Optimal Evaluation Timeline

Follow this structured approach to properly test your new mattress:

1. Week 1-2: Initial Adjustment
   • Allow your body to adapt to the new sleep surface
   • Expect some initial stiffness as your muscles adjust
   • Note any immediate pressure points or discomfort
2. Week 3-4: Active Testing
   • Try different sleeping positions intentionally
   • Assess temperature regulation through multiple nights
   • Evaluate motion isolation with a partner if applicable
3. Month 2-3: Long-Term Assessment
   • Monitor for developing pressure points or sagging
   • Track changes in sleep quality and morning stiffness
   • Consider professional input from a chiropractor if needed

Professional Evaluation Techniques

Use these methods to objectively assess mattress performance:

• Spinal Alignment Check: Have someone photograph your side-sleeping position to analyze whether your spine maintains neutral alignment
• Pressure Mapping: Use a simple towel test – if you can slide a hand under your lumbar area with difficulty, the mattress may be too firm
• Temperature Testing: Monitor if you wake up overheated more than twice weekly, indicating poor thermal regulation

Common Evaluation Mistakes to Avoid

When to Consider a Return

These clear indicators suggest your mattress isn’t working:

• Persistent pain that lasts more than 30 minutes after waking
• Visible sagging deeper than 1.5 inches that develops within 6 months
• Consistent overheating despite proper bedding and room temperature
• Partner disturbance causing frequent sleep interruptions

Long-Term Considerations and Environmental Impact of Mattress Returns

Beyond the immediate return process, understanding the broader implications of mattress returns helps consumers make more responsible purchasing decisions.

Durability and Longevity Analysis

Mattress lifespan varies significantly by material type, impacting return decisions:

Environmental Impact of Mattress Returns

Returned mattresses create significant ecological consequences:

• Landfill contributions: Approximately 80% of returned mattresses end up in landfills due to sanitation concerns
• Carbon footprint: Transporting a king-size mattress generates about 120kg CO2 emissions
• Recycling challenges: Only 56% of mattress materials are typically recyclable

Emerging Industry Trends

The mattress industry is evolving to address these concerns:

1. Extended warranties: Many manufacturers now offer 10+ year coverage to reduce returns
2. Modular designs: Some brands allow replacing only worn components
3. Sanitization technology: New UV treatment processes may enable mattress refurbishment

Responsible Return Decision Framework

Consider these factors before initiating a return:

• Repairability: Many sagging issues can be resolved with a mattress topper
• Donation options: Local charities may accept gently used mattresses
• Manufacturer warranty: Often provides solutions without full return

Special Scenarios: Navigating Complex Return Situations

While Costco’s mattress return policy is generally straightforward, certain situations require special handling.

Returns Without Original Packaging

For online mattress purchases requiring original packaging, follow these professional techniques:

1. Contact Costco Logistics immediately (1-888-426-7826) to explain your situation
2. Alternative packaging solutions:
   • Use heavy-duty contractor bags (6-mil thickness) for foam mattresses
   • Secure with nylon straps every 12 inches for compression
   • Include original tags and documentation inside the packaging
3. Photographic evidence: Take timestamped photos showing:
   • Mattress condition from multiple angles
   • All components being packaged
   • Clear images of any identifying labels

Frequently Asked Questions About Costco’s Mattress Return Policy

What exactly does Costco consider “resalable condition” for mattress returns?

Costco requires returned mattresses to be in like-new condition with no stains, odors, or physical damage. The mattress must retain all original tags and packaging materials, especially for online returns.

Minor compression from normal testing is acceptable, but visible sagging (>1.5 inches) or body impressions typically disqualify the return. Memory foam mattresses must be recompressible to original packaging size for online returns.

How do I return a mattress purchased online versus in-store?

For online purchases, contact Costco.com to initiate the return and repackage the mattress in its original vacuum-sealed packaging. In-store purchases simply require bringing the mattress to the returns desk with your receipt.

Online returns may involve FedEx pickup, while warehouse returns often provide loading assistance. Always call your local warehouse first for large item returns.

Are there any mattresses exempt from Costco’s generous return policy?

Yes, exceptions include mattresses sold by third-party vendors through Costco Next, clearance/discounted items marked “non-returnable,” and custom orders like split mattresses or adjustable bases. Always check your receipt or product page for special return conditions. Some premium brands may have manufacturer warranties that supersede Costco’s policy.

What’s the best way to repackage a memory foam mattress for return?

Use these professional techniques: 1) Gradually compress the mattress using ratchet straps, 2) Slide it into the original plastic sleeve or heavy-duty contractor bags, 3) Secure with nylon straps every 12 inches, 4) Include all tags and documentation inside the packaging. Allow several hours for this process and consider having two people assist.

How does Costco’s mattress return policy compare to other major retailers?

Costco’s no-time-limit policy is exceptionally generous compared to competitors’ 30-120 night trial periods. However, their condition requirements are stricter than specialty mattress companies that allow more visible use. Unlike some retailers, Costco doesn’t charge restocking fees but requires original packaging for online returns, which others may not.

What should I do if my local Costco refuses a mattress return?

Follow this escalation protocol:

1) Politely request the warehouse manager,

2) Contact regional returns at 425-313-8100,

3) Provide documentation of mattress condition and purchase details,

4) Reference Costco’s satisfaction guarantee policy.

Having timestamped photos of the mattress’s condition significantly strengthens your case.

Can I return just the mattress if I bought a bed bundle?

Officially, Costco requires returning all bundle components together. However, some customers report success returning just the mattress if other items remain unused. Your chances improve if:

1) The base is clearly unopened,

2) You’re within 90 days of purchase,

3) You have all original packaging.

Always confirm with customer service first.

How long does it take to receive a refund for a returned mattress?

Refunds typically process within 3-5 business days after Costco receives the return. Original payment methods (credit cards) are fastest, while checks may take 7-10 days. For in-store returns, you’ll often receive immediate credit. Online returns require warehouse inspection before processing, which can add 2-3 business days to the timeline.
