Simba mattress (double) (Rotherhithe)

Got a double size simba mattress I
Bout 3 years from new
Only me slept on it
Turned (not flipped) and steamed every 2 weeks
It is big and cumbersome
On the plus side
I'm on first floor with communal balcony door so can be lowered down over the balcony without using the pesky stairs
And parking available right outside if that helps
Have added a stock photo for now
Will edit and add photos of actual mattress in the morning
Thanks for lookin
