I’d like to preface this by saying I’m pretty young, so my apologies if this is a dumb question!

I’ve never had a bed frame before but I’m currently looking into purchasing the BJÖRKSNÄS one. I have a box spring and a mattress and was wondering if this bed would support the box spring/if it would look funny if I stacked it with the mattress.

Also, if I were to use my box spring, should I still get the slats? Or is it supposed to be one or the other?

Thank you :)
