Let's face it, the best memory foam topper for couples is the one that makes them both sleep comfortably at night, isn't it?
If you're a couple who had very different ideas about what a comfortable mattress is, it's going to be difficult to compromise on a mattress and a mattress topper can be the same.
There are many different ways to come to an agreement that's a win/win for both of you and that's what you're about to discover.
Let's assume that you're a woman who likes a fluffy pillow top type of feel and your husband has a bad back and has been told that he needs to sleep on a very firm mattress. How's that going to work for both of you?
First of all, I don't agree with the notion that a hard mattress is good for your back, but that's another article.
What your husband really needs is support in the lumbar area to help him sleep without back pain and that can be achieved by selecting the proper density of mattress or mattress topper.
A memory foam topper should be at least 4 lb. density in order to give proper support. If you can consider buying a memory foam mattress, you should look for a density of 5 lbs. plus.
Anyway, this density will afford some back support for the person with the bad back while giving the other person the softer feel that they prefer.
Another way to compromise, if you have a king size bed is to buy a twin mattress topper for the 1/2 of the bed you sleep on and let your spouse have the mattress without a topper on it.
This is kind of making the best of it while giving each person exactly what they want.
A memory foam topper isn't meant to be a cure all for a totally worn out mattress. While I think that the topper will make some difference for any situation, it won't make a new mattress out of an old tired one.
