How firm is this mattress?

Hi Murray, thank you for your enquiry, The innerspring is firmer as it will not lose its structure due to the Spring frame. The layer of Foam around the spring does make it feel soft. While foam mattress will compress with weight. I hope this helps. For further information on this or any of our other products available, if you follow the link https://www.babyonthemove.co.nz/store-locations/ this will take you to our online store finder.
