John Lewis Hypnos Mattress Review

What is the John Lewis Hypnos mattress guide about?

This review guide delves into the defining features of a luxury mattress, covering construction methods, high-end fillings and spring types. We also compare and offer alternatives to John Lewis Hypnos mattresses. Understanding these luxury mattress fundamentals is crucial for customers before considering alternatives. This insight helps explain why our mattresses, celebrated as the pinnacle of luxury at the most reasonable prices, stand out as the superior choice.

What are the essential characteristics of a high end mattress?

The essential characteristics of a luxury mattress hinge on four main components in its construction: natural fibre content, types of fibres used, gsm of fibres and spring type. These elements determine the production cost and whether the mattress qualifies as a luxury item.

It’s a straightforward equation: if a mattress with cheaper components costs more than one with higher quality elements, you’re paying extra for an inferior product. Remember, a well-known brand name doesn’t automatically signify superior quality. True luxury mattresses invest in premium materials and sophisticated construction techniques to offer unmatched comfort and durability, justifying their price.

To gauge a mattress’s value, focus on these four critical elements:

Natural Fibre Content

• A truly luxurious mattress features 100% natural fibres. Wool, cotton, silk and horsehair surpass synthetic alternatives like the Hypnos eOlus, in ensuring a cool, temperature-regulated sleep. They’re more durable, maintaining shape and comfort longer. Plus, being hypoallergenic and chemical-free, they’re healthier for you and the environment. Their higher cost reflects the superior quality, sustainability and craftsmanship of natural materials.

Types of Fibres

• Luxury mattresses utilise fibres such as wool, cashmere, silk, horsehair, flax, coir and cotton for their unparalleled quality and benefits.

High GSM of Fibres

• GSM (Grams per Square Meter) measures fibre density in a mattress. A higher GSM means more fibres per square meter, leading to a plush, supportive sleep surface. It ensures comfort, supports even weight distribution and promotes durability. The higher the GSM, the more luxurious the mattress, reflecting in its price due to the cost of dense, high-quality materials.

Spring Type

• Calico pocket springs, encased in natural fabric and hand-tied, set the standard for luxury. They offer superior breathability, individual spring movement for targeted support and minimal motion transfer. Used by elite brands, these springs elevate a mattress’s comfort and longevity, marking its luxury status.

What type of springs do Hypnos mattresses at John Lewis utilise compared to Winstons Beds?

Calico Pocket Spring

• Features: Calico pocket springs are known for their exceptional craftsmanship, with each spring individually hand-tied with twine and encased in breathable, natural calico fabric. This design allows for independent movement, superior responsiveness and precise body contouring, reducing pressure points and improving sleep quality.
• Luxury Level: They are considered the most luxurious spring type, offering premium comfort and sustainability.
• Cost to Produce: 1600 calico spring unit for a king size mattress, the cost is approximately £250.
• Usage: Winstons Beds use these springs. Hypnos mattresses do not.

Spunbond Pocket Spring

• Features: This system involves springs wrapped in spunbond fabric, a cost-effective material that provides good support and comfort. However, it lacks the luxury and individual responsiveness of calico pocket springs.
• Comparison: While not as luxurious as calico pocket springs, they are not inferior; they offer a different value proposition. A mattress with spunbond springs should ideally cost less unless it significantly exceeds in other areas like GSM of natural fibres.
• Cost to Produce: 1500 pocket spring unit for a king size mattress costs approximately £85.
• Usage: Both Winstons Beds and Hypnos mattresses use these springs.

Micro Springs

• Features: Micro springs are small, thin springs used as a cheaper alternative to comfort fibres. They add support but lack the plushness and durability of more luxurious materials.
• Quality: Initially used by Winstons Beds, they were discontinued in favour of higher GSM of fibres and calico springs due to their subpar performance.
• Cost to Produce: A 2000 micro spring layer for a king size mattress costs approximately £30.
• Usage: Winstons Beds no longer use these springs, focusing on quality. Hypnos mattresses still include them.

What do Hypnos mean by “reactive spring” and “active turns”?

Hypnos frequently highlights “ReActive™ pocket springs” and the concept of “active turns” in their mattresses. Active turns refer to the coil count within each spring, with the suggestion being that more coils allow the spring to better adapt to the sleeper’s body, offering tailored support and distributing pressure evenly. The ReActive™ springs, with up to 10 active turns, claim to enhance comfort, support and mattress ventilation, promoting a cooler, more hygienic sleep environment.

However, it’s essential to view these terms with a critical eye. In the mattress industry, all pocket springs are inherently “reactive” to pressure and movement and the number of turns—a range typically between 8 to 10—does not alter a mattress’s fundamental qualities. Whether a spring has 8 or 10 turns, or whether a mattress contains 1500 or 1600 pocket springs, does not, in our professional opinion, impact the sleep experience.

What matters more is the type of spring used and ensuring the spring count is within an optimal range. A count below 1500 might not offer sufficient support, while exceeding 3000 springs often means incorporating micro springs. Micro springs, being less costly than natural fibres, can reduce the natural fibre content in the mattress. This substitution can affect the mattress’s breathability and durability since natural fibres offer superior moisture regulation and longevity. Therefore, the key is finding a balance, ensuring a spring count that provides adequate support without sacrificing the benefits of natural materials.

In summary, while Hypnos’s emphasis on “ReActive™ pocket springs” and “active turns” may imply superior technology, the practical difference in comfort and support between varying numbers of turns or slight variations in spring count is minimal. Focus instead on the quality of materials, the overall spring count within the recommended range of 1500 to 3000 and the presence of natural fibres for a truly luxurious and supportive mattress experience.

What is eOlus fibre used by Hypnos and is it natural?

eOlus fibre or recycled fibre comfort pad, utilised by Hypnos in their mattresses, originates from recycled polymer-based bottles. This process involves reusing discarded plastic bottles, transforming them into a fibre without employing harsh chemicals. Polymer-based bottles, commonly made from plastics like PET (polyethylene terephthalate), are widely used for packaging beverages and other products.

eOlus cannot be considered a natural fibre. Natural fibres are derived directly from plants (like cotton or flax), animals (such as wool or silk), or mineral sources and undergo minimal processing. In contrast, eOlus is synthetically produced from man-made materials, thus placing it in the synthetic fibre category.

When a mattress incorporates eOlus or any synthetic fibre, it cannot be classified as 100% natural. This distinction is crucial for consumers seeking purely natural products for their health benefits, environmental impact, or personal preferences. Therefore, mattresses containing eOlus, despite their sustainable attributes, should not command the same price as those made entirely from natural materials, reflecting the difference in material origins and the value associated with natural fibres.

Why is mattress GSM so important?

GSM stands for Grams per Square Meter and is a key indicator of the density and quality of fibres used in a mattress. A higher GSM means a denser, more plush mattress, offering greater comfort and durability. This is because the mattress contains more of the premium fibres that provide support and regulate temperature for a better night’s sleep.

If you’re comparing two mattresses that both use premium fibres, but one has a higher GSM than the other, the higher GSM mattress should logically be more expensive. The reason is straightforward: fibres are the most costly component in mattress production. A higher GSM indicates that more material has been used, elevating the production costs. Consequently, a mattress with more GSM demands a higher price tag.

Therefore, if a mattress with a lower GSM is priced higher than one with a higher GSM, it raises concerns about value for money. In essence, you’re likely paying more for less, indicating a discrepancy between price and quality. Always check the GSM when choosing a mattress, as it directly reflects the comfort, quality and value you’re getting.

If Hypnos doesn’t disclose the GSM of their mattresses, how can you determine if you have a higher GSM?

Understanding the approximate GSM (Grams per Square Meter) of a mattress, even when it’s not explicitly stated by manufacturers like Hypnos, is possible by calculating it based on the mattress’s dimensions and total weight.

Firstly, calculate the mattress’s area in square meters (m²) by multiplying its width by its length in centimeters (cm) and then dividing by 10,000.

For a one-sided mattress, the areas are approximately:

• Single – 1.71m²
• Small Double – 2.28m²
• Double – 2.57m²
• King – 3m²
• Super King – 3.6m²

For a double sided mattress, the areas double:

• Single – 3.42m²
• Small Double – 4.56m²
• Double – 5.14m²
• King – 6m²
• Super King – 7.2m²

Next, to calculate the GSM, you need the total weight of the mattress and the weight of the springs. Subtract the spring weight from the total mattress weight to find the weight of the fibres. The approximate weight of 1500 pocket springs ranges between 21kg to 35kg, varying by the type and size of spring.

For example, if a king-size double-sided mattress weighs 50kg and contains 1500 pocket springs, subtract the spring weight from the total (let’s say 30kg for this calculation), leaving the fibre weight. Multiply this fibre weight by 1000 to convert it into grams. Finally, divide this number by the area in square meters of the mattress to get the GSM. If the mattress is single-sided, ensure you use the corresponding area in your calculation.

This method gives you a rough estimate of the GSM, helping you assess the density and quality of the mattress’s materials compared to others, even when the GSM is not directly provided by the manufacturer.

Now that you understand the factors determining a mattress’s quality, it becomes clear. A mattress featuring 100% natural fibres, a higher GSM of these fibres, a more luxurious spring type and hand-stitching incurs higher production costs, marking it as superior. Conversely, mattresses lacking these elements should not command the same price, as they represent an inferior product.
