A normal 6' bed with central support should be able to take 2x 3' mattress's - the 5' don't often have the central support - so you may get a "roll in to the middle" effect ?! Double check the length before you order anything though ! LaRedobt do conjoined 3' fitted bed sheets ?! Which may help keep it all together ?! Failing that, a 6' deep sided fitted sheet should do the same ! :-)
I really wanted something a bizt more upmarket than IKEA - something like a solid oak or similar frame, possibly something made by a small workshop. I had considered Treske so something similar to that would be more what I'm looking for.
Does anyone know of places where I can buy a continental bed frame in the UK? My Google search so far hasn't found much. We are looking for a wooden frame that would take 2 x 2'6" or 3' mattresses. Good quality rather than budget, so perhaps in the £1k - £2k price range. dH is currently in the spare room as old bed is in desperate need of replacement, so I am keen we are reunited with a lovely new bed!
