This super king size mattress is made by Slumbernight in Ireland and would make a suitable mattress for a super king bed in a guest room. D2D mattresses have to be of a certain standard before we will sell them in the super king size and the Highlander mattress meets these standards.   Budget mattresses are not suitable to be made into super king mattresses because they are unable to carry the weight of someone sleeping towards the centre of the mattress sufficiently well.  Having said that, the price of this mattress still falls well below what you should expect to pay for a super king size mattress in Ireland. To prove this, we have looked into the cheapest price that other retailers sell super king mattresses in Ireland for and here is what we found (June 08):
