At 10cm deep, the Simba Hybrid Cot Bed Mattress has a slimmer profile than an adult mattress, which is normal for cot bed designs and helps little ones get in and out safely as they grow. Simba publishes very little detail on its product page, so we can't tell you about the layers inside, any trial period or guarantee. If those details matter to you, and with a purchase for a baby they usually do, it's sensible to ask Simba directly before you buy.

Why should you choose this mattress?
If you already trust the Simba name and want a hybrid design scaled down for a cot bed, this is the brand's option. A hybrid construction usually combines springs with foam, which in principle means support alongside a softer sleeping surface.
Key features & layer details
Knitted top cover
A 315g knitted cover that is removable and machine washable, so spills and nappy leaks are easier to deal with.
Baby side Simba Renew layer
A 50mm layer of Simba Renew, a polyester-based fibre made from recycled plastic. It is heat-treated for the right firmness and density, which gives a firmer surface for a baby.
Aerocoil spring layer (Toddler side)
A responsive layer of high-carbon steel pocket springs that Simba describes as ideal support for toddlers aged 1 to 3. It gives a growing child support underneath the softer layers.
Toddler side medium-feel Simba Renew layer
A medium-feel layer of Simba Renew that forms the medium-firm core of the toddler side. It gives a steady middle feel without being hard.
Toddler side cushioning Simba Renew layer
A more cushioned comfort layer that Simba describes as soft, cloud-like support. It sits on the toddler side and makes that surface softer than the baby side.
Layer details from simbasleep.com and mattressnextday.co.uk product pages, October 2026.
Best suited for?
Cot beds
At 10cm deep, this slimmer profile is made for cot bed designs, which helps little ones get in and out safely as they grow.
Children
The cot bed sizing and low 10cm depth suit growing little ones, since it keeps the sleeping surface closer to the floor for getting in and out.
It's not right for anyone who wants full transparency before buying. Simba's page gives only the price and dimensions, with no construction breakdown, firmness description, trial, guarantee or certifications listed. Cautious parents who want to verify materials and safety standards up front will need to contact Simba before committing.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.
