Slatted bit soft

Hey now I sleep for quite some time with this slatted frame and also have a soft mattress to have, say can not have both.
Either the slatted frame appears to be very stable in spite of its lightness, or a soft mattress. Both no too soft.
You should think about what you need I more of a sleeper on soft ground'm one may be hard of the parts, then probably the the slatted frame should be there then lie on the mattress with 7 zones carrying the body properly.
I hope I could help a little.
