Wooden bed slats for DIY project (Dublin)

Hi, looking for wooden bed slats for my DIY project, also could use wooden bed base (unpainted). Offcuts of plywood, chipboard wooden board, laminated flooring would be appreciated too. Small amount, not a trailer, so could be collected with a small trolley. Up to 100-120cm in length (or I can cut with hand saw in half for transportation if it's 2m long bed base side part). Not painted. Please see some examples in the photos. Thank you!
