Hi my mattress is from yourselves , it is about 145 width by 200 cm .. would this fit the double ,, if so I will take !
It sounds like you might have a king size mattress. Standard UK mattress sizes are;
Double - 190cm x 135cm
King - 200cm x 150cm
Standard UK sized mattresses will fit the Prestwood bed frame, I would suggest trying to establish whether you have a King or Double mattress and buy the correlating sized bed frame
Kind Regards, Dreams
