Hi Amanda, Thank you for your enquiry, The Travel Cot Cover fits all standard rectangular travel cots sized up to 105cm long and 80cm wide (when assembled). As we are not stockists of Phil & Ted products, we would recommend contacting them direct to confirm whether this sizing would be suitable for use with your Portacot. Alternatively, if you follow the link https://www.babyonthemove.co.nz/store-locations/ this will take you to our online store finder. Here you can find contact details for your nearest Baby On The Move Store where one of our team experts will be happy to assist you further in your product search and help answer any product questions you may have. We hope this has helped with your query.
