Our bed is a double divan with 4 drawers. No idea what sort of mattress is on top but it's certainly nothing fancy. We got it 17 years ago and it wasn't hugely expensive. It definitely doesn't feel as comfy any more, I don't feel any loose springs or anything but it creaks quite a bit! and most importantly I wake up (even through the night) with pains in my hip and leg. I only get these pains at night so I'm wondering if it's the bed? If so do we need to shell out for a whole new bed including the base or will a new mattress be enough? I know if I go to a store I'll get the hard sell from the salesperson so just want to get some real-life feedback. Thanks.
