Have ordered this slatted frame, because I bought a cold foam mattress and learned through information on the net that necessarily a slatted frame with min. 28 bar is needed for this type mattress and a mattress cover, if you have full warranty on these want.
A compliment to the forwarding: Although only "free curbside" was suggested, the good man has snatched the slatted frame and brought me up in the apartment :)
