Disenchanted, we have the £44.04 mattresses for both ds1 and ds2, they are seriously comfy and the boys are really pleased with them. We bought them the mydal bunk bed frame and cannot believe the good quality for the price it cost. Not sure where you are planning on buying from but we went to Warrington for ours 2 weeks ago and dh checked the stock levels before he left. He and FIL went for store opening and got two out of the last three mattresses - they are very popular indeed! Hope you manage to get what you need .
