We had an ikea mattress that was too soft for me and I would get back pain in the mornings. We decided to invest in a good mattress since it is really important for me.
First, we went to the store and there was absolutely no helpful person in the store and they just wanted to sell their mattress with barely any information about back problems and how mattresses would help, just giving their random ideas. Then, after we thought we found a good mattress that is not too firm nor too soft and has even memory foam on it, they told us that we can try it and if we don't like it we can change it with absolutely no charge so we purchased the mattress. But, after sleeping on this mattress, I have been having back pains worse than ever. Now I rather sleep on the couch than this mattress so I don't wake up with terrible back pain.
I called their service and they say that there's no problem and I can change it, but I have to pay $50 for the delivery. I am now screwed because I have to go to a store with no expert at all and choose randomly another mattress and pay $50 again to deliver it and just hope that it is better than this one, which has no guarantee and I might have to pay $50 again to change that one God knows for how long.
So in short, never ever buy anything from sleep country. I wish someone had told me about it before I get deceived by their advertisements.
