futon bed and mattresses (Easton BS5)

A futon folding bed base, with multiple mattresses. They can be layered up in one big bed as shown, or they could be used separately/go to separate new homes.

Layer 1: wooden folding base.
Layer 2: thin futon-style mattress/cushion
Layer 3: normal double mattress
Layer 4: foam mattress (which includes a layer of memory foam)

All the mattresses are generally in OK condition, but do have some stains. See photos.

Please make clear when replying which layers (or all 4) you are offering to take.
