Why Our Sleep Experts Loved It

becky says

When it comes to finding the perfect mattress, there are a lot of options to choose from. From memory foam to innerspring, there is a wide range of materials and designs to suit different preferences and needs. The Hypnos Marlow Ortho Deluxe Mattress is a new product from the retailer Mattress Online, which focuses on the high-quality and high-priced segment of the industry. This mattress is a perfect option for those who are looking for a luxurious, supportive, and sustainable sleep experience. In this review, we'll take a closer look at what makes the Hypnos Marlow Ortho Deluxe Mattress so special, who it might be best suited for, and what makes it suitable or unsuitable for certain individuals. Let’s dive into the specifics of each layer within this mattress to gain a better understanding of who will find it suitable.

The ReActive 7-turn Base Layer

The ReActive 7-turn pocket spring system is a unique feature of the Hypnos Marlow Ortho Deluxe Mattress. This system is designed to actively respond to your body shape and provide full-body personalised support. The springs are encased in individual pockets, which allows them to contour around your body shape and ease pressure points. This is different from a traditional innerspring mattress, which has one continuous coil system. This unique pocket spring system provides a more accurate support to your body and reduces the chances of the mattress sagging or losing shape over time.

The ReActive pocket spring system also provides superior edge support. The pocket springs are distributed evenly across the mattress, which means that the edge of the mattress is just as supportive as the middle. This allows you to use the entire surface of the mattress for sleeping, without feeling like you're going to roll off the edge.

Another benefit of this system is that it is highly durable and stable, thanks to the dual heating treatment of the springs. This treatment adds memory to the springs, allowing them to retain their height and shape for a long time. The pocket spring system is also designed to be long-lasting, which means that it will provide the same level of support and comfort for years to come, far outperforming poorer quality support systems like open coil and bonnell spring.

The Wool Comfort Layer

The deep wool comfort layer is an important feature of the Hypnos Marlow Ortho Deluxe Mattress. This layer is made up of sustainably sourced British wool, which is a natural and renewable material that is being used as a comfort filling to provide a soft and cosy feel while you sleep. The wool fibres are naturally breathable too which allows the mattress to wick away moisture and regulate temperature. This helps to keep you cool during the night, making it a great option for people who tend to sleep hot.

The wool comfort layer also provides excellent pressure relief, which is especially beneficial for people who suffer from aches and pains. The wool fibres conform to your body shape, providing a customised and supportive sleep surface that proves to be deep enough to protect you from the ReActive springs beneath. This helps to alleviate pressure on the hips, shoulders, and other sensitive areas of the body, resulting in a more comfortable and restful sleep regardless of your sleeping position.

The wool comfort layer is also hypoallergenic and naturally resistant to dust mites, mould, and mildew which makes it a great option for people who suffer from allergies or asthma or who just provide a cleaner and more refreshing night’s sleep. Another benefit is that the wool is naturally flame-retardant, which means that it doesn't require any chemical treatments to meet safety standards and gives you additional peace of mind.

But what makes this Hypnos mattress any different to other wool mattresses? Well, the Marlow is also hand tufted with higher quality British wool, with the tufting process helping to keep the mattress fillings in place and prolongs the lifespan of the mattress. The wool is also naturally insulating, which means that it helps to keep you warm in the winter and cool in the summer, making it a versatile option for all-year-round use. This is known in the industry as an all-season mattress and is something that has been difficult to replicate with other materials.

Final Thoughts

The Hypnos Marlow Ortho Deluxe Mattress is best suited for people who are looking for a firm, orthopaedic mattress that provides excellent bolstering. It's particularly well-suited for people who suffer from back pain, as the firmness of the mattress and the orthopaedic support it provides can help to relieve pressure points and align the spine. Additionally, the mattress is well-suited for people who are looking for a mattress that is made from sustainable, natural materials, as it is filled with layers of sustainably sourced British wool and cotton. The firmer feel does not completely rule out combination sleepers who might occasionally sleep on their side, as the superbly deep wool fillings have a decent amount of sinkage. With that said, we suspect dedicated side sleepers may have better experience from some of the medium tension variants in the same range. As the final piece of icing on the cake, the brand has been awarded a Royal Warrant from Her Majesty Queen Elizabeth II, which attests to its high quality and reputation. It also comes with a 10-year guarantee, so you can buy with confidence that your investment will last for many years to come.

Key Performance Indicators KPI question mark

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews. For example, a firm pocket spring support layer is more breathable and offers better back support but may prove unsuitable for side sleepers, the reverse is true for a soft-medium tension reflex foam support layer. This is one of 100+ datapoints considered when generating the below ratings.


*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • Back Sleepers
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.


  • Breathability
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Stability
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.


  • Initial Odour
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

Traditionally handcrafted

Traditionally handcrafted mattresses can offer a level of quality and attention to detail that is not always possible with machine-made products. The skilled craftsmanship that goes into making a handcrafted mattress can result in a product that is of a higher quality and that will last longer. 

Double-sided for long-lasting performance

The benefits of a double sided mattress are that you get twice the surface area of comfort layers. The real-world practicality of this means that you flip the mattress as well as rotate allowing for better settlement of fillings which increases longevity, while reducing the chance of dipping or spring problems that may otherwise occur. Ultimately the mattress will likely last longer and remain comfortable for a greater duration.
