About the Silentnight Safe Nights Lullaby Cot Bed Mattress
Last checked
A breathable polyester core defines this 70 x 140cm Silentnight cot-bed mattress, rather than springs, foam blocks or deep natural fillings. It is firm, 5 of 5, with a softer-feeling cover over a supportive inner structure, which is the right emphasis for a newborn mattress: babies need a flat, resistant sleep surface, not adult-style cushioning. Firmness is the point here. The foam-free polyester build is conservative in luxury terms but sensible in cot-bed terms; compared with adult memory-foam mattresses or pocket-sprung nursery hybrids, this is about airflow, washability and stable support rather than pressure-relief contouring. The removable hypoallergenic cover washes at 40°C, and the separate inner sleep surface means the mattress can still be used while the outer cover is being cleaned, a practical detail with more nursery value than an extra comfort layer. Silentnight also describes the surface as chemical-free and safety-tested in a SATRA-approved lab, though “chemical-free” is best read as a reassurance about the sleep surface rather than a technical material category. The spec is honest for a nursery mattress: firm polyester support, washable hygiene, and breathability ahead of plushness.
Parents moving a baby from a bedside crib into a cot bed are the clearest fit, especially where the priority is a firm newborn surface with easy cleaning built into the design. Sleep settling is the strongest theme in the feedback: babies are described as adapting well, staying comfortable and seeming less hot overnight, which lines up with the breathable polyester core and the lighter, washable cover rather than contradicting the spec. Hygiene is a real strength. Praise repeatedly lands on the cover coming off easily, washing without fuss and feeling soft enough on top while the mattress remains supportive underneath, so the “soft surface, firm support” wording appears to match how it behaves in use. The weakness is less about failure and more about expectation management: it is described as solid and practical rather than transformative, and there is no repeated evidence here of premium padding, luxury natural fibre feel or adult-mattress-style pressure relief. For parents wanting a firm, washable, breathable cot-bed mattress for a newborn, this is the right call. For families wanting a more luxurious nursery build with richer natural fillings, look at premium natural-fibre cot mattresses instead.

Popped this SBM in the cot and it feels nicely firm with a soft cover, which suits me fine. Our little one seems to settle quicker, and I like that the cover comes off for a wash without any drama. The breathable feel is a comfort, especially on warmer nights. Not a miracle worker, but a solid buy for the money.
Trustworthy item with ample support. Baby remains cool and cosy throughout the night thanks to the breathable core. A good, firm comfort grade for newborns. Washable cover is a thoughtful bonus.
With a cushioned, supportive sleep surface and a removable, washable cover, our Lullaby mattress is the perfect addition to your little ones room.
Our baby sleeps amazing! He now sleep, rolls over and enjoyed the comfort of his bed! Going from a Next to me bed to a cot bed was the best transition and he did amazing with it!
