I have bought a new Sealy Postupedic geltex king size bed and I found that on the first night it sagged in the middle. I can feel it pulls me in to the middle and if I lie on my back the hip towards the middle is lower giving me back ache. I sleep alone. Is this normal settlement. I prefer to sleep to one side which I forced last night and there is no dip on that side. Please help?
In your case Carol we would not expect a product to dip in such a way in such a short period of time from purchase, but factors such as the base and the body weight of the person using the bed will all have an effect. If the base is slatted, there may be a central support bar, which can cause dipping or ridging in that area of the mattress. This can be alleviated by placing a thin barrier, usually (3-5mm) MDF over the slats to provide the mattress with a uniform surface upon which to sit. There is an industry tolerance for settlement, but this should only apply after a longer period, certainly not after the first night.
If it’s not the base then it may be a manufacturing fault especially if you’re really sinking into the middle of the mattress. In any event, we would suggest contacting the store from which you bought the product and raising the issue with them to see if they can offer any advice or a solution. Alternatively, if you get no satisfaction to your query with them, you could contact the Furniture Ombudsman to see if they can help.
