We only bought the mattress a few months ago but it was really cheapo (think tesco value ) and it is really awful.
PIL are staying the weekend in october to look after ds while we are away and I just can't let them sleep on it and I know they won't sleep in our bed if we tell them to.
So will a mattress topper make a big difference to comfort? They are quite expensive and I don't want to waste money on something that isn't going to make a big difference- or shall we cut our losses and buy a nice new one?
