Mattress Forum

I was hoping to get some help with this. I just purchased this mattress from Sleep Country Canada. I had been using an old mattress for some time now, so any new mattress I tried out was better than my old one. After doing a little reading on my new purchase, I am somewhat concerned that my mattress, although it feels great now, will quickly lose it's appeal. I'm not at all in the know when it comes to mattresses so I was hoping for some insight about this specific mattress and if it's a decent one or something I should consider exchanging. It's a queen and I got it on a promotion for around $500. That's just the mattress.

If that link doesn't work, it's simply in Contour Collection and it's the Cooper. I believe it is made by Spring Air.

If I did have to exchange it, I'm considering this one:

If that link doesn't work, it is simply in Contour Collection and it's called Heidi Eurotop.

My only other worry with my mattress right now is that it will sleep too hot, especially in the summer (or winter when the landlords blast the heat) or when there is more than one person on the mattress. 

Thanks for your help. I hope to get some replies and some insight.
