I have a queen size IKEA bed frame that I want to make slats for as I don't like the curved LUROY slats that they come with. My father previously made bed slats for a single sized bed from 10 or so 2"x4" beams of a cheap hardware store wood.
The queen bed frame is 60" or so wide, so my thought was to do the same with generic lumber, but have the beams cut to the 60" width.
Alternatively I'm considering buying 12 1"x2" framing lumber beams instead as the 2x4 ones seem overkill.
Would the thinner slats be strong enough and are there any issues with putting a mattress on them if the slats aren't as wide?
