Artisan 004 mattress grade F?

Firstly thank you for send your mattress range so promptly.

I would be interested in purchasing a Grade F Artisan 004 King size (5ft)in medium for my son (5ft 7 weighs approx.

11st 8).

I appreciate that there could be a wait however due to limited funds this is my only option.

If at any time this does become available could you please contact me.

Many Thanks
