Mattress

I've had a really bad back all this week, and I think it started by my trying to sleep on the different side of my bed last weekend for a change.  What-a-mistaka-to-maka!  The springs in my mattress are apparently all messed up, at least on one side of my bed, and I haven't been the same since that uncomfortable night's sleep.  I've put off having to get a new mattress for so long, but I don't think I can leave it any longer.  I might take the chance on ordering one online - it might mean not being able to test it before I buy it, but they are so much cheaper, I don't have to deal with the sales people at a mattress store, and they normally have generous return policies.  Time to do my online research and try to identify which online review sites are actually genuine.  That can be tricky...
