Memory foam mattress topper by the brand Panda London, size "UK Super King" (200 ×180 × 5cm). Unfortunately I need to let it go as it doesn't fit my new bed after moving. I bought it new from their website (€250 + shipping), and have used it for about a year and a half. I have always used it with a mattress protector over it (in addition to bed sheets) so it is in perfect condition, looks and functions as when I first got it - no stains, marks, tear, etc. (It might look like the topper is bumpy in the photos, but that is because I had to put it over my existing bedding! It becomes completely flat/smooth when fitted on the right sized bed.) It's made of memory foam, so probably won't be for you if you prefer firm mattresses, but perfect for someone who's looking for a topper you can 'sink' into. It's extremely soft and high quality, I have been very very happy with it. I still have the original box which I am happy to give you, but the mattress won't fit as it initially came vaccum sealed.
