Upgrade beds

I don't mind the level of energy that each bed has to offer, it is the uncomfortable rating that come with some beds irritates me ! The level of energy on each bed indicates how much time your sim would takes to recover from sleep but some beds just randomly yield an uncomfortable mood which I find it so annoying, and I try to avoid those beds and instead I chose the high end ones but the problem is, these beds don't always match the room theme so I always find myself with bed crisis when building a house. I don't understand the notion behind with the uncomfortable rating on devs part, I honestly think this is a dumb idea.
