A great mattress is an investment in your comfort and health, but even the most durable products can face wear and tear over time. That’s where warranties come in they protect your purchase and give you peace of mind. However, not all warranties are equal, and many buyers overlook the fine print.
The zero-gravity foam warranty is one of the most transparent and reliable in the UK mattress industry. It ensures that your mattress remains protected against defects, material faults, and premature sagging for years to come. This comprehensive guide explains everything you need to know about the zero gravity foam warranty, including terms, coverage limits, exclusions, and the replacement policy process.
What Is a Zero Gravity Foam Warranty?
A zero gravity foam warranty is a formal agreement between the manufacturer and the buyer that guarantees the product’s performance and quality for a specific period. It covers manufacturing defects and structural faults that could affect comfort or longevity.
The warranty reflects confidence in the product’s design, durability, and craftsmanship all backed by a strong product guarantee UK.

Key Coverage Areas Include:
- Structural defects in the foam core.
- Cracks or splits in the foam material under normal usage.
- Permanent indentations deeper than the standard limit (usually 2.5 cm).
- Faulty zippers or cover stitching issues.
- Early sagging not caused by improper handling or base support.
With these inclusions, the zero gravity foam warranty gives you assurance that your mattress is built to last.
Duration of the Warranty
The zero gravity foam warranty typically lasts between 10 to 15 years, depending on the brand and model. Most premium UK manufacturers offer a full 10-year product guarantee, while some extend partial coverage up to 15 years with pro-rated replacement terms.
Warranty Duration Breakdown:

|---|---|---|
| Full Warranty | 1–10 years | Manufacturer covers all costs |

Mattress Warranty Terms Explained
Understanding mattress warranty terms can be tricky. Manufacturers often use specific phrases that describe coverage conditions. Here’s what they mean:
Common Warranty Terms
| Term | Meaning |
|---|---|
| Full Replacement | The manufacturer provides a new mattress if a defect is proven within the full warranty period. |
| Pro-Rated Coverage | You share the replacement cost depending on the mattress age. |
| Indentation Limit | Minimum depth (usually 2.5 cm) before the warranty applies. |
| Proper Base Requirement | Warranty valid only if the mattress is used on a compatible bed base. |
| Non-Transferable | Coverage applies only to the original purchaser. |
These mattress warranty terms are standard across most zero gravity foam warranties, helping protect both manufacturer and customer interests.
What the Zero Gravity Foam Warranty Covers
The zero gravity foam warranty ensures that the mattress remains structurally sound and comfortable over its expected lifespan. Below are the core coverage points:
1. Foam Integrity
The warranty covers cracks or splits in the foam under normal use. High-quality zero gravity foam rarely deforms, but coverage ensures protection if it does.
2. Indentation and Sagging
If your mattress shows permanent sagging or indentations deeper than 2.5 cm, you can file a claim under the zero gravity foam warranty.
3. Cover Defects
Issues such as frayed stitching, broken zippers, or torn covers due to poor manufacturing are included.
4. Manufacturing Defects
Any production faults affecting comfort, durability, or foam response are fully covered under the product guarantee UK.
5. Replacement Policy
Depending on warranty terms, the mattress may be replaced or repaired free of charge during the coverage period.
What’s Not Covered in the Warranty
While the zero gravity foam warranty is generous, it doesn’t cover everything. Understanding exclusions prevents unpleasant surprises later.

Common Exclusions
- Normal wear and tear from daily use.
- Comfort preference changes (too soft/firm complaints).
- Physical damage such as cuts, burns, or stains.
- Mold or odor due to moisture or poor ventilation.
- Improper foundation or bed base use.

Always read your mattress warranty terms carefully to avoid voiding the agreement accidentally.
Replacement Policy: How It Works
The replacement policy under the zero gravity foam warranty ensures you receive a fair resolution if a defect is confirmed.
Replacement Process:
- Contact Customer Support: Submit a claim with proof of purchase and photos of the defect.
- Inspection: The manufacturer may request an inspection or foam compression test.
- Approval: If the issue falls under warranty terms, approval is granted.
- Replacement or Repair: The mattress is replaced or repaired according to the product guarantee UK policy.

This process ensures every customer receives quick and fair assistance.
Warranty Essentials to Remember
- Keep your receipt or proof of purchase.
- Always use the mattress on a compatible base.
- Avoid moisture and protect it with a cover.
- Check the indentation depth limit (usually 2.5 cm).
- File claims promptly after noticing defects.
These points help maintain the validity of your zero gravity foam warranty throughout its lifespan.
Warranty vs Product Guarantee UK
| Feature | Zero Gravity Foam Warranty | Product Guarantee UK |
|---|---|---|
| Coverage | Manufacturing defects, sagging, foam cracks | Broader — includes satisfaction and delivery support |

| Claim Process | Requires inspection & approval | Often retailer-managed |
| Cost | Free or pro-rated after 10 years | Varies by brand |

Both offer strong buyer protection, but the zero gravity foam warranty provides deeper coverage for long-term foam integrity and structure.
