Why Are Our Prices So Low?

We source genuine branded mattresses from trusted European suppliers, including overstock, clearance and end-of-line stock. By buying these products at reduced prices, we are able to pass the savings directly on to our customers.

All mattresses sold by Magnus Dream are 100% genuine, brand new and unused, and have never been returned by a customer.

Please note that the outer cardboard box may show signs of storage or transit, such as dents, creases, tears or additional protective tape/wrapping. This does not affect the mattress inside, which remains brand new, unused and factory-compressed/wrapped.

If the original outer box is too badly damaged to provide adequate protection, the mattress may be placed into another Emma mattress box to ensure safe storage and delivery.

Please note: Our mattresses are sold without the manufacturer’s 10-year guarantee. Returns, faults and after-sales support are handled directly by Magnus Dream in accordance with our Returns Policy.

Firm Comfort & Temperature Regulation

The Emma Diamond Hard combines innovative Diamond Degree® graphite foam, pressure-relieving comfort foam and a supportive 7-zone cold foam core to provide firm, comfortable support.

The graphite-infused upper layer helps dissipate excess body heat, while the comfort foam adapts to the body’s contours for effective pressure distribution.

The 7-zone support system provides targeted support across different areas of the body, making the mattress suitable for back, side and front sleepers.

Its breathable foam construction promotes ventilation, while the removable and machine-washable cover makes everyday care easier.

Designed for single-sided use, the mattress should be rotated from head to foot approximately once a month.

Features & Benefits

Trusted Emma Quality: Designed by Emma to combine adaptive comfort, responsive support and a breathable hybrid construction for a comfortable night’s sleep.
Adaptive Hybrid Comfort: A combination of AirAdapt™ foam, MemoryAdapt™ foam, supportive HRX foams and AeroFlex™ pocket springs provides a balanced mix of cushioning, pressure relief and responsive support.
Responsive Body Support: Individually encased AeroFlex™ pocket springs respond independently to pressure and work with the adaptive foam layers to provide support across the sleeping surface.
Reduced Motion Transfer: Individually responsive pocket springs and adaptive foam layers help limit the transfer of movement across the mattress, reducing disturbances when your partner changes position during the night.
Enhanced Breathability: Open-cell AirAdapt™ foam and the AeroFlex™ pocket spring construction encourage airflow through the mattress, helping to create a fresher and more comfortable sleeping environment.
Pressure-Relieving Comfort: MemoryAdapt™ foam adapts to the shape of the body and helps distribute pressure more evenly for comfortable support throughout the night.

Mattress Unpacking Instructions

To protect the environment and ensure safety, all our mattresses are carefully vacuum-sealed and tightly packaged before shipping. Your new mattress will arrive at your home rolled up and vacuum-packed to ensure the product's safety during transportation.

Carefully cut open the outer packaging using only the knife included in the pack.

Unroll the mattress onto your bed, carefully cut the vacuum packaging, and allow the mattress to expand.

After approximately 6 hours, rotate the mattress 180°.

Allow at least 48–72 hours for full expansion. Some mattresses, particularly hybrid models, may take longer.

Please allow additional time for full expansion:
Most mattresses expand within 48–72 hours, but some may require additional time to reach their full size, shape and height, particularly hybrid models due to their layered and pocket-sprung construction. As some of our mattresses may have been vacuum-packed for a longer period before sale, this is normal and does not affect the quality or performance of the mattress.
