It rather depends on quality much the same way as in the UK. When we bought our place the beds were real cheap and nasty that apparently cost a couple of hundred lira inc. mattress. We replaced them with better quality ones bought in a shop in Fethiye. (With the Megri Lokanta on your right walk up the road and shop is at the point where it bends to the left)We paid around £250 including a good mattress, iron headboard etc. Good value really.
