I'm buying my first ever sofa and can't decide. I've found this <a class="break-all" href="//onewww.oakfurnituresuperstore.co.uk/sofas/view-all-sofas/indus-green-velvet-right-facing-chaise-sofa" rel="nofollow" target="_blank">onewww.oakfurnituresuperstore.co.uk/sofas/view-all-sofas/indus-green-velvet-right-facing-chaise-sofa and really like it. I can't tell if the two parts clip together or are free standing. If they are free standing, will the two parts keep sliding away from each other? Has anyone bought this?
