As found here on the Argos web site: Classic High Sleeper with Blue Sofa Bed Frame - Pine

This one is just over two years old and is the pine finish frame, with blue cushions and matress. The matress supplied is not an original Argos one, it's a Memory Foam replacement.
The frame alone is still £500 at Argos. The bed is very solid, nothing wobbly about it at all. Sleeps one child on the top, with a pull out bed at the bottom, over which you rearrange the cushions, to accommodate a visitor.
The frame is in great condition, all bolts, screws and fittings are complete and intact, with none sheared or pulled from the wood. It's largely unmarked, apart from the desk area which has pen marks on it. There's nothing that won't come off with a sheet of fine sandpaper and a £10 tin of wax plus some elbow grease. An hour's work and this bed would look like new!
It's 95cm wide by 195cm long and (at the highest point of the rail) 178cm high.
The bed will have to be disassembled to remove it from the room it's in. I can do that for you and will reduce to as few parts as possible. We'll make a note of what goes where for reassembly. Minimal tools required, a flat bladed screwdriver, a Pozidrive screwdriver and an Allen key are all that's required. All covers have been washed.
No longer required due to house move.
£150. Blythe Hill area.
