About the Silentnight Amsterdam Miracoil Ortho Mattress
Last checked
Back-care firmness is the purpose of the Amsterdam, rather than a side benefit. This is an extra firm, 5 of 5, orthopaedic mattress built around Silentnight’s Miracoil spring system, with Eco Comfort Fibre above it, a damask cover, hand-tufting and a 24cm depth. Miracoil sits in the traditional continuous-spring family, so the support is broad and springy rather than individually responsive in the way a pocket-sprung or memory-foam hybrid mattress behaves; the manufacturer’s three-zone language gives some shape to the support, but it is still not a profile-hugging construction. Honest spec for the price tier. The comfort layer is also conservative: recycled Eco Comfort Fibre is breathable, vegan-friendly and foam-free, but it is not a plush pressure-relief layer, and the tufting deliberately tightens the surface to keep the fillings in place and preserve that firm feel. Edge support and no-roll-together claims make sense for a taut Miracoil build, especially compared with softer open-coil mattresses, though couples should still expect more bounce than from a denser pocket-sprung unit. The single-sided design reduces maintenance to rotation only, and the weights are manageable rather than punishing, at 22.5kg for a double and 26kg for a king.
For back sleepers wanting a flat, braced surface, the spec lines up with the strongest owner sentiment: positive reviews repeatedly mention back-pain support, a properly firm feel and a well-made finish for the money. Its 4.6-star average from 479 ratings is carried by buyers who wanted an unforgiving orthopaedic mattress and felt they received exactly that, with one substantial positive account saying the firmness was more liveable than the label suggested for a 13.5-stone sleeper. The same firmness divides opinion sharply. Low-scoring reviews describe the surface as too hard, with one person needing a topper after back pain, while other unhappy accounts raise more serious durability complaints: spring feel through the top fabric, softening after a few weeks, movement causing the whole mattress to bounce, and noise loud enough to disturb sleep. Those complaints cut against the stable-edge and no-roll-together promise, so the practical reading is that the Amsterdam suits people who prioritise a rigid, cool, foam-free surface over cushioning and motion isolation. Side sleepers with sensitive shoulders or hips may find the Eco Comfort Fibre too lean, and lighter bodies may not compress the spring unit enough to get much give. If you’re a back sleeper who wants a very firm, low-maintenance orthopaedic mattress, this works. If you’re a fidgety couple or need softer pressure relief, a pocket-sprung hybrid in the next price tier makes more sense.

Specifications
Manufacturer specifications without the jargon, easy to scan and compare.
No roll-together
Crafted with innovative technology, this item ensures independent sleeping zones, eradicating disruptions caused by movement by one person, thereby offering you a serene night's sleep. Furthermore, this distinctive attribute aims to promote even weight distribution, essentially contributing to better sleep posture and relieving areas of high pressure, ensuring you wake up refreshed and invigorated each morning.
24cm deep
Featuring a substantial depth of 24cm, this mattress provides ample cushioning and support, catering to varying sleep preferences with its luxuriously cozy yet supportive feel. The enhanced depth also suggests a higher level of material build, implying improved durability and longevity, encouraging an extended mattress lifespan that's a beneficial investment for the long run.
Extra Firm
Boasting an 'Extra Firm' rating, this mattress offers unparalleled support, ideal for individuals who prefer a structured sleeping surface or those with certain back conditions. However, be mindful, as it may fall short on plush comfort characteristic of softer options, potentially making it less suitable for side sleepers or those who favour a more cushioned feel.
Orthopaedic Support
This king-size sanctuary of comfort grants sterilised hypoallergenic filling that ensures sleep is not disrupted by common allergens. Furthermore, an impressive tally of 2000 individually nestled springs provides the spine with correct alignment, tackling backaches and promoting a healthy sleeping posture.
Fire Resistant
Ensuring safety during your peaceful slumber, fire resistance is a crucial feature that reduces the risk posed by potential accidents involving flammable materials. Furthermore, it demonstrates the manufacturer's commitment to adhere to strict safety standards, prioritizing your well-being over all else.
National Bed Federation Approved Brand
Receiving approval from the National Bed Federation indicates that the product meets specific industry standards and quality benchmarks. This approval serves as a reassurance of the product's reliability and durability, though discerning buyers may still want to consider personal comfort preferences.
Eco Comfort Fibre
Encompassing sustainable and recyclable materials, Eco Comfort Fibre contributes to a greener environment while offering substantial comfort. This technology, simultaneously breathable and resilient, aids in maintaining an ideal sleep temperature and delivers an uninterrupted, restful night.
Chemical treatment-free
Opting for a mattress unmarred by chemical treatments essentially heightens your exposure to a more organic, safer sleeping environment. This invariably furthers your health prospects by diminishing potential toxic threats, directly contributing to a wholesome, restorative slumber.
Lower back support
You'll find comfort in knowing that lower back support benefits considerably from this mattress's construction. It can work wonders in maintaining spinal alignment, thus enhancing sleep by reducing discomfort, particularly for individuals accustomed to sleeping on their sides.
Damask cover
Woven fabric gives the mattress surface a tighter, smoother feel under sheets, with a patterned thread structure that resists the baggy stretch some softer covers can develop. Spills can sit in the weave, making a protector sensible.
Vegan-friendly
Plant-based or synthetic fillings avoid wool, silk or other animal-derived fibres, leaving the surface suitable for shoppers avoiding animal materials. Check cover materials and fire barrier details where allergies are involved.
Approved by the National Bed Federation
Factory auditing checks that the mattress is made under UK rules for flammability, fillings and labelling, giving you a clearer paper trail for what arrives at home. It doesn't prove comfort, firmness or long-term durability.
5 year guarantee
Fault cover puts manufacturing problems in writing, making a loose strut, failed fixing or collapsed padding less of a gamble after delivery. Accidental damage, fabric marks and poor fitting usually sit outside it.
Hypoallergenic
Hypoallergenic mattresses are the perfect choice for those with allergies or sensitivities, as they protect against allergens and irritants. They're also a great choice for those with asthma or respiratory issues.
Miracoil springs
Linked wire coils spread body weight across the mattress, giving your hips and shoulders a steadier surface and helping reduce the dip towards the middle. Couples may prefer pocket springs for calmer movement.
Reinforced mattress edge
Firmer sides help the mattress hold its shape when you sit or sleep near the border, giving you more usable width across the bed. It won't stop a soft comfort layer dipping under weight.
Handcrafted in the UK
Factory workers assemble and finish the mattress by hand, leaving small variations in stitching or edge detail you may notice up close. It doesn't prove better support or longer life.
Single-sided
Bed-making is simpler because the comfort layers stay on the top face, leaving the underside to stabilise the mattress while you lie on the cushioned surface. Don't flip it over.
