In brief: The Casper Original (8.5/10, ~€495-995) is the best Casper brand mattress available in France. Its patented 3 support zones, AirScape™ ventilation technology and 28 cm thickness make it a reference for sleepers who get hot at night and want targeted lumbar support.

Casper is one of the pioneers of the online mattress, founded in 2014 in the United States. The brand popularised the concept of the universal foam mattress even before Emma arrived in Europe. With millions of mattresses sold worldwide and a strong presence in luxury hospitality, Casper embodies American expertise in sleep comfort. In 2026, the Casper Original remains the brand's flagship model in France.

The Casper philosophy: sleep as science

Casper has always adopted a data-driven approach to mattresses. The brand employs engineers and ergonomists who study the biomechanics of sleep to design products adapted to the majority of body types. This corporate culture translates into concrete innovations: patented support zones, lab-tested materials, and a design that prioritises function over marketing.

The result is a mattress that doesn't try to be the softest or the most spectacular, but the most scientifically adapted to the human body in sleep position. It's this rigour that makes Casper frequently recommended by back health professionals in the United States.

The history of Casper

Founded in 2014 in New York by Philip Krim, Jeff Chapin, Luke Sherwin, Neil Parikh and T. Luke Sherwin, Casper Sleep revolutionised the American mattress market by offering a single universal model sold exclusively online. The concept met immediate success: $1 million in revenue during the first 28 days of launch.

Since then, Casper has expanded its range to the entire bedroom (pillows, sheets, bedding) and established itself in Europe with an offer adapted to local standards and dimensions. The brand is also present in luxury hospitality, reinforcing its quality image.

The culture of innovation

Casper invests heavily in R&D. The brand has its own research laboratory in New York, where engineers test dozens of foam configurations, perforations and support zones before validating a product. This scientific approach is visible in every detail of the Casper Original.

Casper Original: detailed analysis

Rating: 8.5/10 | Price 140x200: ~€495 | Price 160x200: ~€795

Detailed technical composition

The Casper Original stands out with its multi-layer foam construction with 3 patented support zones. At 28 cm thickness, it is thicker than the average foam mattress, allowing it to stack several functional layers without compromise.

Layer 1 — AirScape™ perforated foam The top layer uses AirScape™ technology: a perforated foam that allows air to circulate freely through the mattress. Unlike classic memory foams that tend to trap heat, the Casper offers active ventilation that reduces the sensation of nocturnal overheating. The perforations create micro-air channels that function as a passive air conditioning system.

Layer 2 — Zonal transition foam This intermediate layer is cut into 3 zones of differentiated firmness — the core of Casper's innovation. The upper zone (head and shoulders) is softer, the central zone (hips and lumbar) is firmer, and the lower zone (legs) offers intermediate support.

Layer 3 — High-resilience foam The Casper Original base is made of CertiPUR-US certified high-resilience foam. This layer ensures mattress durability by preventing long-term sagging. It constitutes the support foundation that works in synergy with the upper layers.

The 3 patented support zones

The core of Casper's innovation lies in its 3-zone differentiated firmness system:

• Head and shoulders zone: softer to avoid pressure points at the shoulders, particularly critical for side sleepers
• Hips and lumbar zone: firmer to maintain spinal alignment and prevent pelvic sagging
• Legs zone: intermediate support for homogeneous comfort from head to toe

This architecture aims to solve the classic problem of foam mattresses: uniform comfort that doesn't match real anatomical needs. According to the Sleep Foundation, differentiated support significantly improves sleep quality for people with lumbar tension.

AirScape™ technology

AirScape™ technology is not just a marketing gimmick. The perforations in the top foam create a network of air channels that allow continuous ventilation. Result: the mattress surface temperature stays 2 to 3°C lower than a standard foam mattress. For sleepers who get hot at night, this difference is noticeable from the first nights.

Strengths:

• 3 patented support zones for optimised spinal alignment
• AirScape™: superior ventilation to standard foam mattresses
• 28 cm thickness: generous surface comfort and deep support
• High-resilience foam base: durability and stability
• 100 nights trial satisfaction or money-back
• 10 years warranty
• OEKO-TEX Standard 100 and CertiPUR-US certifications
• Removable cover for easy maintenance

Weaknesses:

• Price climbs in larger sizes — over €700 in 160x200
• No spring technology — motion isolation remains inferior to hybrids
• Availability sometimes limited on certain sizes in France
• Finish adequate but less premium than Tediber on unboxing

Sleeping sensation: The sensation is medium (5/10), with a welcome that envelops without trapping. Back sleepers particularly appreciate the reinforced lumbar support. Side sleepers find a good balance between shoulder softness and hip support. People who get hot at night notice a real difference compared to classic memory foam mattresses.

Comfort by sleeping position

Back sleeper: This is the optimal position for the Casper Original. The reinforced lumbar zone maintains the natural curve of the spine without creating pressure points. Support is precise and the sensation of support is immediate.

Side sleeper: Very good comfort. The soft zones at the shoulders allow natural decompression, while hip support preserves spinal alignment. Side sleepers under 85 kg will be particularly satisfied.

Stomach sleeper: Adequate. The 28 cm thickness and firmer central zone prevent pelvic sinking. Medium-weight stomach sleepers find an acceptable compromise, but people over 90 kg will prefer a firmer mattress.

As a couple: Good adaptation. Motion isolation is satisfactory thanks to the foam layers that absorb movements. However, it remains inferior to a hybrid mattress like the Simba.

The minor downside: the price climbs quickly in larger sizes. In 160x200, it often exceeds €700, placing it above the Emma Original and close to the premium segment.

Casper accessories: the Original pillow

The Casper Original pillow extends the sleep experience with an airy memory foam construction that follows the cervical curve. It is an excellent complement for sleepers who want a coherent set.

The pillow uses the same philosophy as the mattress: perforated foam for ventilation, differentiated ergonomic support and removable cover. For sleepers suffering from cervical pain, the Casper mattress + pillow combination offers a complete solution.

Against Emma Original, Casper wins on ventilation and zonal support. Emma wins on price. The choice depends on your priority: if you get hot at night or have mild lower back pain, Casper is superior. If you're looking for the best value for money, Emma remains ahead.

Against Simba Hybrid, Casper is cheaper but also less technological. Simba offers superior motion isolation thanks to micro-springs, but Casper compensates with more refined lumbar support and a more contained price.

Against Tediber, Casper positions itself as the technical and breathable choice. Tediber appeals with its French image and enveloping welcome, but Casper scores objective points on breathability and zonal support. For a back sleeper with lumbar tension, Casper is superior. For a side sleeper seeking immediate comfort, Tediber may be preferable.

Sleeping position and Casper Original

Position	Suitability	Comment
Back	Excellent	Reinforced lumbar zone = optimal support
Side	Very good	Soft welcome at shoulders
Stomach	Adequate	28 cm thickness prevents pelvic sinking
Couple	Good	Satisfactory motion isolation
Hot sleeper	Excellent	AirScape™ = superior ventilation

Verdict: for which sleeper should you choose Casper?

Choose the Casper Original if:

• You tend to get hot at night and want better ventilation
• You suffer from mild lumbar tension and need zonal support
• You sleep on your back and want reinforced lumbar support
• You appreciate scientific design and technical patents
• You are looking for a thick and comfortable mattress (28 cm)

The Casper Original may not be for you if:

• Your budget is under €500 (see our budget selection)
• You want maximum motion isolation for a couple (opt for the Simba Hybrid)
• You prefer a very soft and enveloping welcome (Casper remains assured and structured)
• You want a spring mattress (see our hybrid comparison)

Rotation every 3 to 6 months is sufficient to maintain homogeneous comfort. The Casper Original is not reversible — it has a dedicated top face.
