Good morning. I hope you are well, during the corona virus era. I am re-covering an osteopathic treatment table, that has a 28 1/2 x 74 wood base with a 30x 74 firm latex foam on top. I want to place wool batting between the upholstery fabric (medical grade faux leather), and the foam. I am stapling the fabric to the underside of the wood table. Obviously I do not need to cover the bottom of the foam, that is laying on the wood. Two questions. How much wool do I need (compared to your measurement chart)? Is a different technique required to secure the wool in place? Thanks
Hello Mark,
First, I would suggest that your foam dimension be .5″ larger than the wood base dimension in each direction, so ideally, your foam would be 29.5 (30 is probably fine) x 75.
(1) Instead of wrapping the wool all the way around (as you would a cushion), you’re just wrapping it around the top face + the thickness of the foam, so [30 + (thickness x 2)] x [74 + (thickness x 2)]. then I would add 2″ to each dimension (width & length) for wrapping under and stapling to the bottom.

Hi Carla, if I’m book wrapping two latex cushion cores (3” base and 2” topper) for a layered sofa seat with 1 inch 750gsm wool, would you expect this to add any inches to the seat height. With 4 layers of wool in total, I’m hoping for a little extra height!
Hi Emily,
Four layers of wool will feel lofty at first. Eventually, with use, it will compress and become more felt-like.
