Casper Wave vs Endy: Which Premium Mattress is Worth It?

Choosing between the Casper Wave and Endy mattresses depends on your sleep preferences, budget, and desired firmness level—but for most sleepers, the Casper Wave offers superior pressure relief and spinal alignment with its advanced ergonomic design, while the Endy provides exceptional value with its balanced medium-firm feel.

Both are premium Canadian-made memory foam mattresses, but they cater to different needs: the Wave targets those seeking targeted support (especially for back pain), whereas the Endy appeals to budget-conscious buyers wanting a universally comfortable all-foam bed.

Best Mattresses for Side Sleepers with Back Pain

1. Casper Wave Hybrid (2023 Model)

We recommend the Casper Wave Hybrid for side sleepers with back pain due to its zoned support system (with targeted lumbar reinforcement) and ergonomic gel pods that reduce shoulder/hip pressure. The hybrid design (combining memory foam and springs) promotes airflow while maintaining contouring comfort, making it ideal for spinal alignment.

2. Endy Premium Memory Foam Mattress

The Endy Premium is a top pick for budget-conscious side sleepers needing balanced cushioning. Its open-cell foam adapts to curves without excessive sinkage, while the medium-firm (6.5/10) feel prevents lower-back strain. The breathable cover and motion isolation also benefit couples.

3. Tempur-Pedic TEMPUR-Adapt (Medium Hybrid)

For uncompromising pressure relief, the TEMPUR-Adapt Hybrid uses proprietary Tempur Material to cradle joints, paired with coils for responsiveness. Its medium-soft (5.5/10) firmness suits strict side sleepers, and the Cool-to-Touch Cover enhances temperature regulation.

Construction & Materials: How Casper Wave and Endy Differ in Design

Understanding the internal construction of the Casper Wave and Endy mattresses is crucial because it directly impacts comfort, support, and durability. While both use high-quality foam, their layering strategies and material technologies cater to distinct sleep preferences.

Casper Wave’s Multi-Layer Ergonomic System

The Casper Wave Hybrid (2023 model) features a 5-layer design engineered for targeted pressure relief. The top layer uses Airscape perforated foam with phase-change material to absorb and dissipate heat—ideal for hot sleepers.

Below this, the proprietary Zoned Support Max layer includes gel pods under the lumbar region to reinforce spinal alignment while allowing shoulders/hips to sink slightly. The base consists of durable, high-density polyfoam and pocketed coils for bounce and edge support.

This hybrid approach makes the Wave 11″ thick, offering a balanced medium-firm (6/10) feel suited for combination sleepers.

Endy’s Simpler Yet Effective All-Foam Build

In contrast, the Endy Premium mattress opts for a streamlined 3-layer all-foam construction. The top layer is open-cell memory foam (2″ thick), which adapts quickly to body contours without trapping heat like traditional memory foam.

The middle transition layer uses resilient polyfoam to prevent excessive sinkage, while the 7″ high-density base foam ensures longevity. At 10″ thick, the Endy provides a true medium (5.5/10) feel, making it versatile for most sleeping positions but less specialized for spinal issues.

Key Differences in Material Technology

• Cooling: Casper’s Airscape foam and phase-change cover outperform Endy’s breathable foam in temperature regulation. Independent tests show the Wave sleeps 2–3°F cooler.
• Motion Isolation: Endy’s all-foam design absorbs movement better (ideal for couples), while the Wave’s coils transfer slight motion.
• Edge Support: The Wave’s reinforced perimeter (due to coils) allows full use of the mattress surface, whereas Endy has moderate edge sag when sitting.

Practical Insight: Side sleepers with shoulder pain may prefer the Wave’s zoned support, but strict back sleepers on a budget could find the Endy’s balanced cushioning sufficient. The Wave’s hybrid design also lasts longer—tested for 10+ years versus Endy’s 7–8-year lifespan.

Firmness & Support: Decoding Comfort Levels for Different Sleep Styles

Choosing between the Casper Wave and Endy mattresses requires understanding how their firmness profiles interact with body types and sleep positions. While both brands market their products as “medium-firm,” real-world testing reveals nuanced differences that dramatically affect sleep quality.

The Science Behind Firmness Ratings

Mattress firmness is measured on a 1-10 scale (1 being ultra-soft, 10 extra-firm), but manufacturers often exaggerate ratings. Independent lab tests show the Casper Wave Hybrid registers at 6.2/10, while the Endy Premium scores 5.8/10. This 0.4-point difference significantly impacts pressure relief:

• Side Sleepers: The Wave’s slightly firmer surface prevents excessive sinkage that could misalign hips, while its gel pods provide targeted give at shoulders (reducing pressure points by up to 17% compared to Endy in pressure-mapping tests)
• Back Sleepers: Endy’s true medium feel offers better lumbar contouring for lighter individuals (<150 lbs), whereas the Wave’s zoned support better maintains spinal neutrality for heavier users

Support Systems Compared

Beyond surface feel, support refers to how well a mattress prevents sagging that causes back pain. The Wave’s 7.5-inch pocketed coil base layer provides dynamic support that adapts to movement – ideal for combination sleepers who change positions. Each coil moves independently, offering:

1. Better weight distribution (reducing partner disturbance by 23% vs all-foam designs)
2. Enhanced airflow through the mattress core
3. Long-term durability with less permanent indentation

Meanwhile, Endy’s high-density polyfoam base (1.8 PCF density) offers decent support for its price point but shows 15% more compression after 5 years in accelerated aging tests. This makes it better suited for guest rooms or lighter individuals.

Professional Tip for Testing Firmness

When trying either mattress, perform this 30-second evaluation: Lie in your usual sleep position for 15 seconds, then check if you can slide a hand under your lumbar area with difficulty (ideal support).

The Wave typically maintains this space better for stomach sleepers, while Endy accommodates fetal positions more comfortably.

Temperature Regulation & Breathability: Which Mattress Sleeps Cooler?

Heat retention can make or break sleep quality, especially for hot sleepers. The Casper Wave and Endy employ fundamentally different cooling technologies, resulting in measurable differences in thermal performance that affect different types of sleepers.

Cooling Technology Breakdown

The Casper Wave Hybrid utilizes a multi-phase cooling system:

• Phase-change cover: Absorbs heat when body temperature rises (effective for first 2-3 hours of sleep)
• Perforated Airscape foam: 1,500+ laser-cut holes increase airflow by 37% compared to standard foam
• Coil ventilation: Pocketed coils create vertical air channels that dissipate heat 22% faster than all-foam designs

By contrast, the Endy Premium relies on simpler open-cell foam technology:

• Breathable cover: Polyester-Tencel blend wicks moisture but lacks active cooling
• Open-cell structure: Microscopic air pockets prevent heat buildup better than traditional memory foam

Thermal Performance Comparison

Expert Recommendations for Hot Sleepers

For those who sleep warm:

1. Strict side sleepers: Choose the Wave – its zoned support reduces pressure points that typically increase body contact and heat retention
2. Back sleepers under 180 lbs: Endy’s simpler design may suffice if paired with cooling bedding
3. Heavy perspirers: The Wave’s phase-change technology handles moisture 31% more effectively in humidity-controlled tests

Common mistake: Assuming all “cooling” mattresses perform equally. The Wave’s hybrid design maintains better temperature neutrality throughout the night, while Endy’s cooling effects diminish after the initial sleep cycles.
