Double Mattress Topper (Oaklands nr Welwyn AL6)

Top quality, 3 inches thick and was expensive when new. Used for a short time and then put in storage for some time. I'm having a clear out and was going to sell this but it has slightly discoloured in a couple of areas . It does not smell bad at all. This is washable (it would need to be at a launderette as it is big)
