Sofa bed mattress (Wicklow town)

Ikea FYRESDAL sofa bed foam mattress.
Originally came with two foam mattress inserts which would fit in either side of the mattress cover.
We only used one mattress and would fold the extra material for the other underneath as two mattresses were too high for the seating area we used it on.
Just to note the empty side of the cover has some damage and staining, but not an issue seen as this side tucks under.
The side that faces up is perfect.
Cover is removable for cleaning, just washed it myself so it's perfectly clean.
