The Silentnight Amsterdam Miracoil Ortho Mattress is a wonderfully firm mattress with a supportive, orthopaedic feel.
Featuring extra firm support, this is a sturdy mattress that gives your back the care and support it needs. The Miracoil spring system provides the dependable support that Silentnight are renowned for. The edges are stable and prevent roll-off. The middle is equally firm, so you won't roll together either.
Whilst the Amsterdam is very firmly supportive, it doesn't sacrifice your comfort. All wrapped up safely inside the elegant damask cover, there's a thick and luxurious layer of Eco Comfort Fibresâ„¢. Eco Comfort Fibresâ„¢ are resiliently supportive fibres that cushion you comfortably.
With Eco Comfort Fibresâ„¢, there's no overheating. These clever fibres help to evaporate body heat so you can enjoy a cooler, fresher sleep. 100% sustainable and recycled, Eco Comfort Fibresâ„¢ help you to care for the planet as you sleep!
The surface of the Amsterdam boasts a tufted finish - the hallmark of a good, firm bed. The button-like tufts are expertly applied to the mattress by hand. These tufts lock all the filling layers firmly in place and extend the longevity of your mattress.
The Amsterdam is the perfect choice if you're looking for a cleaner, healthier sleep. It's both chemical- and foam-free for your peace of mind. Helping guard against allergens and dust mites, this mattress is hypoallergenic so you can enjoy a sneeze-free slumber.
As a single-sided mattress, it's easy to keep your new Amsterdam in the great condition you expect. Simply rotate it regularly - there's no need to flip it over!

This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.

Verified Purchase
not a comfortable mattress at all in my opinion, not enough padding for me, feels like sleeping directly on the springs and too firm, also the left and right edges of the mattress feel softer/lower than right down the middle (spine) of the mattress which is rock hard, I wouldnt recommend this mattress
Verified Purchase
It was definitely a great purchase having a disability and finding the right type was important to me enabling good support and allowing me a decent night's sleep which is really important for ones wellbeing, very comfortable and a price that was excellent.
