I ordered mattress on 3rd August and tried to get used to it but frankly, the item  is not fit for purpose and not as described. Ive asked for a full refund. Item's spring system is faulty- springs are not arranged evenly and make sudden movements/ noise when sitting or lying on the mattress. This defect makes it not possible to use for sleeping on. It is not as advertised - as 'medium' sleep comfort at 23cm thick. It only measures 19cm thick and has a 'baggy' appearance. Plus, it is only single sided so cannot be turned - this is not stated on the sales information. Poor quality, avoid this item.
