Sealy Millionaire President Firm Mattress

4.9 star rating


List Price £XXX.XX
PostureTech Zero Deflection Springs 29cm Depth Firm Tencel Cover

Select Size Size Guide


Providing all the support you need while sleeping, the Sealy Millionaire President Firm Mattress feels incredibly firm, even for those whose stature is larger than average. This is thanks to the PostureTech Zero Deflection Construction Springs. Due to the small diameter of the springs, the spring count is higher than standard open coil designs. This resilient spring system produces the firmest level of support, optimum levels of comfort and incredible responsiveness.

The mattress surface is stable and firm too due to the Edge Guard technology. The mattress edges are reinforced with a high density foam strip to increase supportiveness and prevent sagging. Even if you sleep right on the edge of your mattress it won’t bulge, and the reinforcing technology helps prevent you from rolling off.

Stay fresh as you sleep while the natural Tencel fibres work to absorb, relocate and release moisture. These breathable fibres have a higher absorption level than cotton and the lack of moisture keeps dust mites at bay while preventing any bacteria from forming. Also helping to keep you dry, cool and fresh are the Sealy Smart Fibres. Containing Purotex, friendly bacteria is released onto the mattress fabric to reduce moisture and mould while repelling dust mites. Endorsed by Allergy UK, this natural cleaning solution is essential for providing allergy sufferers with proper sleep in a hypoallergenic environment.


PostureTech Zero Deflection Springs

Sealy's PostureTech Zero Deflection spring system combats both weight and movement to avoid motion disruption during your sleep. It also helps to ensure stable and firm support across the entire sleep area.

29cm Depth

This mattress is approximately 29cm deep.

Firm Support

Good for people who sleep on their front or back.

Tencel Cover

The mattress cover incorporates Tencel, an innovative fibre that naturally cools you and manages moisture. Tencel also helps to combat bacterial growth and is soft and comforting.

Orthopaedic Support

Designed to offer a firmer sleep surface, providing targeted support for your back and joints.

Reinforced Edges

The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.

No Roll Together

Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.

Pressure Relieving

This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.

Turning Handles

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.


The mattress has fillings on both sides. Double-sided mattresses need to be turned regularly to keep them in good condition.

NBF Approved Product

Peace of mind and reassurance - the manufacturer of this item is an approved member of the National Bed Federation's Code of Practice.

Made in the UK

This item has been manufactured in the UK.
