Hi there, if it's from Ikea I'd say you should be able to find it in Ikea!

Thank you I visited a few stores in Sydney , bo concepts, king furniture , project 82 and finally jimmy possum and decided on the Massimo and Milmo sofa with ottoman from jimmy possum, many reasons, not only because of the impeccable quality of the sofas and the fact it's Austrlaian made, but after visiting the store twice my husband would fall asleep instantly whilst sitting on them, and that to me was the clincher. Very happy with the staff and service from Jimmy Possum located at Moore Park , Sydney. So excited, 8 weeks to go...

This isn't a personal recommendation as I have not yet purchased anything from this company, but I've been admiring the timber floating shelves on their website. https://shelvingshop.com.au/product-category/floating-shelves/wood-effect-finish/ Or you can buy the brackets and have the shelf custom made in whatever material and size you want. https://shelvingshop.com.au/product-category/brackets-2/floating-shelving-brackets/  I think hardware stores also sell brackets by themselves. I was thinking of going the custom route because that means I can ensure the brackets will be attached to the studs. I believe you can paint melamine after proper preparation of the surface, but I doubt if you can stain it.
