I bought a Steelcraft portacot for an upcoming trip for my baby who has just turned 6 months - but the mattress/base is very thin and hard (compared with the substantial and comfortable spring cot mattress at home). - Is it safe to use this wool underlay here: https://www.babybunting.com.au/babyrest-lambswool-portacot-underlay-strap.html? - OR this padded fitted sheet here: http://www.urbanbaby.com.au/Padded-Travel-Cot-Sheet#.XAJyZBMzai5? Please let me know thanks.
Red Nose recommends using a portacot/folding cot that meets the Australian Standards. (AS/NZS - 2195).
Portable cots are not designed for the type of mattress that is used in a household cot.
Red Nose recommends the following regarding mattresses in portacots:
“Only use the firm, thin, well-fitting mattress that is supplied with the portable cot. Never add a second mattress or additional padding under or over the mattress, which has been specifically designed for the portacot, as baby may become trapped face down in gaps between the mattress and the sides.”
