Cost just £46 (including delivery), was delivered quick (Parcel-force), excellent vacuum packing and decent quality. Absolutely great value for money considering that the cheapest 4ft small double from Argos costs £77 and is of comparable quality. Bought it along with a memory foam mattress top and a cover and using it in our guest room. Great buy!
Only suggestion that I'd leave for the seller Mr Sleeps is to include the tracking number in the dispatch confirmation email. If you're sending it using Parcelforce, might as well give the customer a tracking reference!
