Support system
A sumptuous mattress, luxuriously filled with sustainable natural fibres. Supported with a clever spring system to offer soothing orthopaedic support.

Individualised springs encased in cloth pockets. Expertly adapting to movement to distribute personalised support to each part of your body.

Stay snuggly all night long. Perfect all year round, wool is a natural insulator and has great temperature regulating properties.

Natural cotton fibres create a perfectly fresh sleeping environment. The soft fillings regulate your body temperature and wicks away moisture.

Helping to promote a healthy sleeping position. Orthopaedic support is specially designed to provide enhanced spinal alignment, joint support and improve posture.

Durable edge-to-edge support provides a maximised sleeping surface for a more secure sleep. Sit and lay comfortably right to the very edge with zero 'roll-off' sensation.

A traditional technique which creates a sturdier and more durable border. The stylish hand side-stitching method is used to improve longevity and edge-to-edge support.

Offering a soothing night's rest by evenly distributing your body weight across the mattress. The pressure point relief provides the ultimate relaxation needed for a deep slumber.

A traditional and elegant design that holds fillings in place whilst enhancing the stability of the mattress. The luxurious tufting ensures zero shifting, shape loss or sagging.

Free from harsh chemicals or irritants or allergens, this product is treated with a natural fire retardant formula. Better for you and the environment.

For the highest standards of quality and safety
Experience a luxurious support sleep with the Hypnos Marlow Ortho Deluxe Mattress.
Sustainable fillings
This mattress is finely filled with cosy natural fibres, welcoming a cool and fresh night's sleep. Constructed of layers of sustainably sourced British wool and cotton. They can be tracked and traced back to their origins with help from Red Tractor and Better Cotton Initiative.
Next to the spring unit is Hypnos' own eOlusâ„¢ fibres, which are made from recycled plastic bottles. These fibres are firmer than normal fillings because of their vertical structure. The fibres are great for added support and soothing pressure points. They are added next to the spring unit for extra durability and stability.
Responsive support
In the core of this mattress is Hypnos' unique ReActiveâ„¢ 7-turn pocket springs. Designed to actively respond to your body shape, the springs offer full-body personalised support. Contouring around your shape, the special springs ease pressure points.
Each spring has been dual heated, which adds memory to the springs, allowing them to retain their height. The treatment increases durability and stability, offering long-lasting performance that never fails.
Orthopaedic feeling
The Marlow has a soothing firm feel, which is great to relieve common back pain. The ortho feel adds a little extra support to your back. It aligns your spine and supports the heaviest parts of your body.
Supportive edge
The mattress border is hand side stitched onto the spring system, so the springs support you right to the very edge. All around the perimeter of the spring unit, rod edging has been added which increases the support around the border. The remarkable edge support increases the maximised sleeping surface, so you can stretch out all night long!
Flip it!
This mattress is double-sided, enjoy the long-lasting performance the Marlow has to offer. Simply flip and rotate the mattress seasonally to make sure the fillings don't settle and flatten.

This is a quality product. It is firm but very comfortable. Although 28cm deep, it is not too difficult to turn and/or flip as per the manufacturer's instructions. Highly recommend.

We were looking to replace our old orthopaedic Sweet Dreams mattress that we had had for about 5 years and had slept on Hypnos in hotels before so decided to shop for one. Mattress Online was the cheapest for the spec after finding that the model names were specific to them. The process was easy with support fast delivery and a fantastic delivery team that ensured the experience was great. The mattress is lighter than the old one making it easier to flip and rotate. Quality was very good as expected. Comfortable, warm sleep that feels firm but also cushioned in a floating sort of feeling With the Hypnos guarantee this should give many years of conditionally sleep
