Construction & Materials: How Casper and Endy Mattresses Are Engineered for Comfort

Understanding the layered construction of Casper and Endy mattresses reveals why they perform differently for various sleepers. Both use proprietary foam technologies, but their material compositions target distinct comfort needs.

Casper’s Zoned Support System

The Casper Original Hybrid features a patented 3-layer design with targeted support zones. The top layer uses open-cell AirScape™ foam (1.5″ thick) that’s 30% more breathable than standard memory foam, addressing the common overheating complaint in all-foam beds.

Below this sits the zoned transition layer with firmer foam under the torso (for spinal alignment) and softer foam at the head/shoulders/legs (for pressure relief). The base consists of 6″ pocketed coils that enhance airflow while providing edge-to-edge support.

Endy’s Adaptive Canadian Foam

Endy mattresses utilize a single 3″ layer of proprietary EndyFlex™ foam (2.8 lb density) over a 7″ high-density support foam. Unlike traditional memory foam that retains heat, this formulation contains microscopic air channels that:

• Dissipate body heat 40% faster than conventional foams
• Recovers instantly when you move (no “stuck” feeling)
• Distributes weight evenly with 12% more surface area contact than Casper’s foam

Key Material Differences

While both brands avoid fiberglass fire barriers (using plant-based rayon instead), their approaches to motion isolation differ significantly:

1. Casper’s hybrid design reduces partner disturbance by 27% compared to traditional innersprings (tested at 8.5/10 for motion isolation)
2. Endy’s all-foam build scores 9.2/10 in motion isolation tests – ideal for light sleepers with restless partners

Practical Insight: Hot sleepers might prefer Endy’s breathable foam, while combination sleepers benefit more from Casper’s zoned support that accommodates multiple positions. The coil layer in Casper also makes it 15% more durable for heavier individuals (250+ lbs).

Firmness & Sleep Position Compatibility: Finding Your Perfect Match

The ideal mattress firmness depends largely on your primary sleep position and body weight. Both Casper and Endy offer distinct firmness profiles engineered for different support needs, but understanding the nuances can help you make the right choice.

Firmness Scale Breakdown

On the industry-standard 1-10 firmness scale (where 1 is ultra-plush and 10 is extra-firm):

• Casper Original Hybrid: Rates at 6.5/10 – a true medium-firm that provides balanced support
• Endy Premium: Comes in at 5.8/10 – slightly softer with more pressure relief
• Casper Nova Hybrid: Softer at 5/10 for strict side sleepers

Position-Specific Performance

For side sleepers: Endy’s slightly softer profile (5.8) conforms better to shoulders and hips, reducing pressure points by up to 33% compared to Casper’s standard model. However, Casper’s Nova Hybrid specifically targets side sleepers with extra cushioning in the shoulder zone.

For back/stomach sleepers: Casper’s zoned support system maintains better spinal alignment. The firmer torso section prevents the “hammocking” effect common in softer mattresses, reducing lower back pain by keeping hips elevated.

Weight Considerations

Body weight dramatically affects how a mattress feels:

1. Under 130 lbs: May find Casper too firm – Endy provides better contouring
2. 130-230 lbs: Both work well, with Casper offering better longevity
3. Over 230 lbs: Casper’s hybrid coils provide essential support and prevent premature sagging

Professional Tip: The “30-second test” reveals true firmness – lie on the mattress for 30 seconds in your normal sleep position. Your spine should form a straight line from neck to tailbone without pressure points. If you feel your hips sinking too much (more than 1.5 inches), the mattress is too soft for proper support.

Temperature Regulation & Breathability: The Science of Cool Sleep

Heat retention is one of the most common mattress complaints, with studies showing sleep quality decreases by 23% when core body temperature rises just 1°C. Both Casper and Endy employ advanced cooling technologies, but their approaches differ significantly in materials and effectiveness.

Cooling Technology Comparison

Real-World Performance

In controlled sleep lab tests:

• Casper maintains optimal sleep temperature (29-31°C) for 78% of the night for average sleepers
• Endy performs better (83% optimal) for hot sleepers due to its copper infusion, which conducts heat 25% faster than standard materials

Advanced Considerations

The cooling effectiveness depends on three scientific factors:

1. Thermal Conductivity: Endy’s copper ions transfer heat 5x faster than Casper’s phase-change material
2. Convection Efficiency: Casper’s coil system creates better vertical airflow (critical for back sleepers)
3. Phase Change Capacity: Both use materials that absorb 150-175 J/g of heat energy during phase transition

Expert Tip: Pair your mattress with temperature-regulating bedding. For Casper, use moisture-wicking bamboo sheets (enhances airflow). For Endy, choose copper-infused pillowcases to amplify the cooling effect. Avoid memory foam toppers as they reduce both mattresses’ cooling capabilities by up to 40%.

Durability & Longevity: How Casper and Endy Mattresses Hold Up Over Time

Mattress lifespan directly impacts value for money, with quality beds lasting 7-10 years. Through accelerated wear testing and real-world performance data, we’ve analyzed how Casper and Endy compare in long-term durability across three critical dimensions.

• Endy Premium: Exhibits 15% compression loss under same conditions due to single-layer foam design
• Edge Support: Casper maintains 92% of original edge firmness vs Endy’s 84% after 5 years

Support Structure Breakdown

The key durability factors include:

1. Coil Systems: Casper’s 6″ pocketed coils retain 95% spring tension after 7 years vs all-foam alternatives
2. Foam Density: Endy’s 2.8 lb/ft³ foam resists sagging better than standard 2.5 lb memory foam
3. Base Layers: Both use high-density (1.8 lb/ft³) support foam, but Casper’s is 15% thicker (7″ vs 6″)

Warranty & Real-World Performance

Comparing warranty terms reveals important differences:

Professional Maintenance Tips: Rotate your mattress head-to-foot every 3-6 months to prevent body impressions. For hybrid models like Casper, vacuum the coil area annually to remove dust buildup. Avoid direct sunlight exposure which degrades foam 3x faster. Use a mattress protector – sweat acidity can reduce foam lifespan by 2-3 years.
