King/double foam mattress topper (GL1)

Giving away this foam mattress topper in good condition. We bought this for our king size bed, but as you can see it would also work on a double (it’s pictured on top of a double bed). The photo makes the foam look discoloured in places but the discolouration doesn’t appear to the naked eye, so I think it must be the lighting. No longer needed as we have upgraded. Needs to go ASAP.
