Replacing an attached memory foam topper
|
We have a Serta Perfect Sleeper North Stellaris with an attached memory foam topper. It was excellent for about 6 months months ... but very quickly started to sag, and now it is much softer and uncomfortable. It went from being fantastic to being very bad within a few months, and it is now about 18 months old. We can't afford a new mattress. Has anyone tried removing the attached topper and replacing it? We need a very firm topper. Can anyone suggest a model? Michael. |
