New to Sex Furniture-HELP!

Ok, so hubby and I sat down to check out some of the ramps and what not. I want to get something to give us a little more spice in our sexual experiences, but there is so much to the furniture section that I am not sure what I should start with. Mind you, Im pretty limited financially too, so $200-$300 items probably won't be affordable for us lol. Im not looking for anything "Crazy kinky" or nothing. Sometimes its hard for me to "stretch" or try new positions because of my bad back, fibroymalgia, muscle and joint issues, etc etc. Yeah, Im falling apart at the ripe 'ol age of 27 LOL. But I want something that will help us to be able to achieve something "new" with each other without going crazy, standing on the table and hanging from lamp posts lol. Any suggestions?
