Junior bed (Leytonstone E11)

Short bed, suitable for child or short adult. Useful for small bedrooms
Mattress size 3ft x 5ft 9ins (90 × 175cm)
Total bed frame size 99 x 183. All in very good condition.
The mattress is a Babywise, Coolmax. Unmarked.
Recently has only been used for occasional sleepovers. I have 1 fitted sheet designed for the size, but full size single would work.
It has been dismantled. I don't have the assembly instructions, but if you have ever put together flat pack furniture, it is very straightforward.
