Casper Mattress Warranty Coverage

The Casper mattress warranty is a 10-year limited warranty that protects against manufacturing defects in materials and workmanship. Unlike a return policy, this warranty is specifically designed to address long-term issues that may arise from faulty construction rather than general comfort preferences.

What’s Covered Under the Warranty

Casper’s warranty explicitly covers:

  • Sagging greater than 1 inch: This measurement must occur without any weight on the mattress and indicates a structural failure of the foam layers.
  • Physical flaws in the foam: Including cracks, splits, or permanent indentations that weren’t caused by improper use.
  • Zipper defects (for models with removable covers): Malfunctions in the zipper mechanism that prevent normal use.

A real-world example would be if your mattress develops a visible depression in the middle after two years of proper use on an appropriate foundation – this would likely qualify for warranty replacement.

What’s Not Covered (Common Exclusions)

The warranty contains several important exclusions that consumers often misunderstand:

  • Comfort preferences: Simply not liking the feel of the mattress isn’t covered.
  • Damage from improper use: This includes stains, liquid damage, or physical damage from pets.
  • Use on improper foundations: The mattress must be used on a firm, flat surface like a platform bed or adjustable base.

For instance, if you place your Casper mattress directly on slats spaced more than 4 inches apart and it sags as a result, this would void the warranty coverage.

How Coverage Changes Over Time

The warranty operates on a pro-rated system after the first year:

  1. Years 1-2: Full replacement for qualifying defects
  2. Years 3-10: Prorated coverage where you pay a percentage of the replacement cost

This means if your mattress fails in year 5, you might pay 50% of the current retail price for a replacement. Casper provides a detailed proration chart in their warranty documentation.

Key Consideration: The warranty is non-transferable and only applies to the original purchaser with proof of purchase. This is particularly important for those buying second-hand Casper mattresses.

How to File a Casper Mattress Warranty Claim: A Step-by-Step Guide

When you encounter a potential warranty issue with your Casper mattress, following the proper claim process is crucial for a successful resolution.

Step 1: Document the Issue Thoroughly

Before contacting Casper, gather comprehensive evidence of the defect:

  • Take timestamped photos: Capture clear images showing the defect from multiple angles. For sagging, place a straightedge across the mattress and measure the gap with a ruler.
  • Record your foundation details: Photograph your bed frame or base to prove proper support (slats no more than 4″ apart for most models).
  • Note purchase information: Locate your original order number or receipt – digital copies from Casper’s website are acceptable.

Pro Tip: Casper often requests a 30-day waiting period after noticing an issue to confirm it’s not temporary. Document the problem initially and again after this period.

Step 2: Initiate the Claim Process

Contact Casper through one of these channels:

  1. Online Form: The most efficient method via Casper’s warranty portal
  2. Phone Support: 1-888-498-0003 (best for complex cases needing explanation)
  3. Email: support@casper.com (include all documentation as attachments)

Expect to provide:
– Your original purchase information
– Mattress size and model
– Detailed description of the issue
– All supporting documentation

Step 3: The Evaluation Process

Casper’s warranty team typically responds within 3-5 business days. They may:

  • Request additional photos or information
  • Ask you to rotate the mattress to rule out temporary body impressions
  • Send a local inspector for significant claims (rare but possible)

Common Challenge: Claims often get denied initially for “normal wear and tear.” If this happens, politely request specific measurements showing your mattress doesn’t meet their sagging threshold (1″ without weight).

Step 4: Resolution Options

Approved claims result in one of these resolutions:

  • Full replacement (Years 1-2): New mattress shipped at no cost
  • Prorated replacement (Years 3-10): Discounted replacement based on mattress age
  • Partial credit: For minor defects not warranting full replacement

Important Note: You’ll typically need to dispose of the original mattress yourself. Some municipalities offer bulk item pickup for this purpose.

Maintaining Your Casper Mattress to Preserve Warranty Coverage

Proper mattress maintenance is critical for both longevity and warranty protection.

The Science of Mattress Degradation

Memory foam and polyurethane mattresses degrade through three primary mechanisms:

Degradation TypeCausesWarranty Implications
Compression SetConstant pressure points, excessive heatCovered if >1″ without weight
HydrolysisMoisture exposure, high humidityVoids warranty if unprotected
Off-GassingNormal chemical releaseNot covered (expected process)

Professional Maintenance Protocol

Follow this 4-step maintenance routine every 3-6 months:

  1. Rotate (Don’t Flip): Casper mattresses are single-sided. Rotate 180° to distribute wear evenly.
  2. Vacuum with Upholstery Attachment: Remove dust and allergens that can break down foam cells.
  3. Spot Clean Only: Use mild detergent (1 tsp dish soap + 1 cup water) – never saturate the foam.
  4. Air Out: Leave uncovered for 4 hours in a well-ventilated area to release moisture.

Advanced Protection Strategies

Beyond basic care, these professional techniques extend mattress life:

  • Climate Control: Maintain bedroom humidity between 30-50% to prevent foam hydrolysis
  • Weight Distribution: For heavier individuals (>230 lbs), use a bunkie board for enhanced support
  • Seasonal Adjustments: In humid climates, run a dehumidifier during summer months

Common Maintenance Mistakes That Void Warranty

Avoid these frequent errors that compromise warranty coverage:

  • Using Cleaning Machines: Steam cleaners or carpet shampooers void coverage immediately
  • Improper Foundation: Using a box spring with slats >4″ apart causes premature sagging
  • Missing Protector: 92% of liquid damage claims get denied for lack of waterproof protection

Expert Insight: The Casper Wave Hybrid requires special attention to its zoned support coils. Avoid sitting on the edge repeatedly, as this can compress the perimeter foam beyond normal wear parameters.

Comparing Casper’s Warranty to Industry Standards: What Makes It Different?

Understanding how Casper’s warranty measures against competitors and industry norms helps consumers make informed purchasing decisions.

Industry Standard vs. Casper Warranty Features

The mattress industry typically offers these warranty benchmarks compared to Casper’s policies:

FeatureIndustry StandardCasper Warranty
Duration10 years (memory foam/hybrid)10 years (all models)
Sagging Coverage1.5″ depression1″ depression
Proration StartYear 3-5Year 3
Transferability25% allow transfersNon-transferable

Key Advantages of Casper’s Warranty

Casper offers several superior protections compared to competitors:

  • Stricter Sagging Threshold: The 1″ coverage standard is more stringent than most competitors’ 1.5″ policies
  • Full Replacement Period: Two full years of non-prorated coverage exceeds the typical 1-year industry standard
  • Zipper Coverage: Includes unique protection for cover zippers, which most warranties exclude

Notable Limitations to Consider

Consumers should be aware of these comparative limitations:

  1. Non-Transferability: Unlike some premium brands (like Tempur-Pedic), Casper doesn’t allow warranty transfers to new owners
  2. Foundation Requirements: Casper’s 4″ slat spacing rule is stricter than the typical 5-6″ industry standard
  3. Professional Inspection Requirement: For claims over $1,000, Casper may require third-party verification

Professional Recommendation: When to Consider Extended Protection

Based on usage patterns, these consumers might benefit from supplemental coverage:

  • Pet Owners: Consider a separate damage protection plan for claw/chew damage
  • High-Weight Individuals: Those over 300 lbs may want to explore reinforced models with specialized warranties
  • Renters: In high-humidity environments, additional moisture protection may be warranted

Industry Insight: Casper’s warranty is particularly strong for edge support claims compared to budget brands, but falls slightly short of luxury brands in terms of transferability and full-coverage duration.

The Environmental and Long-Term Cost Considerations of Casper’s Warranty

Beyond the immediate coverage details, Casper’s warranty program carries significant environmental and financial implications that conscious consumers should evaluate.

Environmental Impact of Warranty Claims

Casper’s replacement process involves important ecological considerations:

ComponentEnvironmental ImpactCasper’s Mitigation Approach
Foam DisposalTraditional polyurethane takes 500+ years to decomposePartners with local recycling programs in 60% of markets
Shipping EmissionsAverage 40kg CO2 per mattress shipmentCarbon-neutral shipping through offset programs
Material RecoveryOnly 20% of mattress materials typically recycledNewer models use 30% recycled content

Total Cost of Ownership Analysis

Evaluating the warranty’s financial impact over 10 years:

  • Replacement Costs: Prorated fees increase from 30% in Year 3 to 70% by Year 9
  • Protection Investments: Quality mattress protectors ($60-$120) typically pay for themselves by preserving warranty eligibility
  • Disposal Fees: Local mattress disposal costs average $50-$100, not covered by warranty

Emerging Industry Trends Affecting Warranties

The mattress industry is evolving in ways that impact warranty structures:

  1. Biodegradable Materials: New plant-based foams may lead to shorter warranty periods but easier recycling
  2. Subscription Models: Some competitors offer “warranty as a service” with monthly protection plans
  3. Smart Mattress Tech: Embedded sensors may soon provide automatic warranty claim documentation

Safety Considerations in Warranty Scenarios

Important health and safety factors to consider:

  • Off-Gassing Periods: Replacement mattresses require 48-72 hours of ventilation
  • Mold Prevention: Warranty claims for moisture damage require medical-grade documentation
  • Fire Retardants: All replacements meet updated CPSC flammability standards

Expert Insight: While Casper’s warranty is competitive today, industry movement toward circular economy models may make the current “replace-and-dispose” approach obsolete within 5-7 years. Consumers prioritizing sustainability should factor this into long-term purchasing decisions.

Optimizing Your Casper Mattress Setup for Maximum Warranty Protection

Proper mattress configuration goes beyond basic assembly to ensure long-term performance and warranty validity.

Engineering-Approved Foundation Specifications

Casper’s warranty requires specific support systems that maintain structural integrity:

  • Platform Beds: Must have slats ≤4″ apart (3.5″ recommended for heavier models like the Casper Wave Hybrid)
  • Adjustable Bases: Require full-contact support (no gap >2″ when flat) and must support ≥600 lbs distributed weight
  • Box Springs: Only approved if less than 2 years old and specifically designed for foam/hybrid mattresses

Advanced Climate Control Recommendations

Environmental factors significantly impact mattress longevity and warranty claims:

  1. Temperature Regulation: Maintain bedroom temperature between 60-75°F to prevent foam hardening or excessive softening
  2. Humidity Management: Use dehumidifiers in climates with >60% average humidity to prevent foam hydrolysis
  3. Air Circulation: Allow 3-5″ clearance on all sides for proper ventilation and heat dissipation

Professional Installation Techniques

Follow these certified procedures when setting up your Casper mattress:

StepProcedureWarranty Significance
1. UnboxingUse plastic cutters (not knives) to prevent accidental slicing of cover fabricPrevents voiding of cover-related warranties
2. ExpansionAllow 48-72 hours for full expansion in a climate-controlled roomRequired for accurate defect assessment
3. AlignmentEnsure mattress is centered with ≤1″ overhang on any sidePrevents edge compression damage

Troubleshooting Common Setup Issues

Address these frequent problems that could affect warranty coverage:

  • Partial Expansion: If mattress hasn’t fully expanded after 72 hours, rotate 180° and apply gentle pressure to stubborn areas
  • Foundation Gaps: Use 1/2″ plywood sheets to bridge excessive slat spacing (must be ventilated with 10+ 1″ holes per sheet)
  • Initial Odors: Normal off-gassing should dissipate within 96 hours – prolonged odors may indicate manufacturing defects

Engineering Insight: The Casper Nova Hybrid requires special attention to its seven-zone support system. Ensure the shoulder relief section (marked by stitched lines) aligns properly with your upper body position for optimal performance and warranty compliance.

Frequently Asked Questions About the Casper Mattress Warranty

What exactly does the Casper mattress warranty cover?

The Casper warranty covers manufacturing defects in materials and workmanship for 10 years, including sagging exceeding 1 inch (without weight), physical flaws in foam layers, and zipper defects on removable covers.

It does not cover normal wear, comfort preferences, or damage from improper use. The first two years offer full replacement, while years 3-10 provide prorated coverage based on mattress age.

How do I measure sagging to determine if it qualifies for warranty?

Place a straightedge across the mattress surface and measure the gap at its deepest point using a ruler. The measurement must exceed 1 inch without any weight on the mattress. Document with timestamped photos showing the straightedge and ruler clearly. For accuracy, measure in multiple locations and take measurements over 30 days to confirm permanence.

Can I transfer my Casper warranty if I sell or give away my mattress?

No, Casper warranties are strictly non-transferable. The warranty only applies to the original purchaser with valid proof of purchase. This differs from some competitors like Tempur-Pedic that allow one-time transfers. Secondhand buyers receive no warranty protection, which significantly affects resale value.

What foundation requirements must I meet to keep the warranty valid?

Your mattress must be supported by a firm, flat surface with slats no more than 4 inches apart. Platform beds, adjustable bases, and bunkie boards are approved, while traditional box springs may void coverage. The foundation must provide continuous support without sagging or gaps exceeding 2 inches when flat.

How does the prorated replacement cost work after year 2?

After the initial two years, you pay a percentage of the current retail price for a replacement. The proration schedule increases linearly: 30% in year 3 up to 70% in year 9. For example, a $1,200 mattress with a year 5 claim (50%) would cost $600 to replace. Original shipping fees may still apply.

What’s the best way to document issues for a potential warranty claim?

Maintain a warranty file with:

(1) Original purchase receipt,

(2) Timestamped photos every 6 months showing mattress condition,

(3) Documentation of your proper foundation, and

(4) Records of all maintenance.

For potential issues, take weekly measurement photos over 30 days to demonstrate the problem’s progression.

Will using a mattress protector void my Casper warranty?

No – in fact, Casper recommends using their waterproof protector or equivalent. However, protectors must be breathable and cannot contain vinyl or other non-permeable materials that might trap moisture. The protector should be washed monthly according to manufacturer instructions to prevent allergen buildup.

How long does the warranty claim process typically take?

Most claims are resolved within 10-14 business days. Simple claims with thorough documentation may be approved in 3-5 days, while complex cases requiring inspection can take 3-4 weeks. During peak periods (January-March), add 5-7 additional days for processing. Always keep your original mattress until the claim is fully approved.
