My husband and I are getting a memory foam bed but we have a co-sleeping 8 month old infant, help!?

I had a memory foam bed and got rid of it because I noticed my shape stayed in the bed longer than advertised. I co sleep now but I wouldn't be too quick to knock parents who choose not to. Some individuals are heavy sleepers or just would not sleep well with a child and for them it is the more responsible choice not to co-sleep. I think most people try to do what they believe is best for their family.
