I'm planning on making a built-in bedhead with 90x45mm pine for the framing along with some VJ paneling for the front. Likely use some oak timber for the top of the bedhead and match with some bedside tables which I'm planning to fix to the bedhead so they're 'floating' in a sense.
My question is, which type of 90x45mm pine should I use? Looking at this but unsure if I need to use treated pine instead? https://www.bunnings.com.au/90-x-45mm-framing-mgp10-untreated-pine-2-4m_p8030079
