Wool batting is a sheet of wool fibers, aligned and layered in sheer sheets on top of each other, over and over until the batt’s desired weight is achieved. A wool batting wrap around latex both is used both when making couch cushions and when making a mattress. Here’s why.
Latex is bouncy. It has a nice rebound to it that keeps body impressions from lasting like they do in memory foam. Wool does not have a bounce. Much of our wool has a crimp to it, which gives it strength and body. A layer or two of wool softens the bounce of the latex and moderates the sponginess feel of the foam. It also smooths out the edges of the foam for a slightly rounded look.
In a way, the wool is considered a pillowtop to the latex, especially if 2 or 3 layers are used. I usually compare our wool toppers to a medium piece of latex, which would be soft for a couch cushions
Wool batting is used to add some puff to your cushion. Sometimes this is an even layer around, sometimes the batting is folded in a pyramid of layers on the top and bottom of the cushions to add a little extra height there and give a rounded look to the cushion.
As I say in the blog post How to choose Firmness for Couch Cushions #4, all fabric has stretch to it, even a woven fabric like a twill has a slight stretch to it. Think of the way a pair of jeans fits snugly fresh out of the dryer, yet loosely when they go into the washing machine. Another trick besides cutting the latex a 1/2″ larger, is to wrap the latex in the wool batting. If the case and the latex are made the same size, adding in a 1/2″ a wool batting wrap will provide that the case will still look full after it has stretched its 3%.
If you ask us to wrap a latex cushion in batting, we neither staple it, sew it or glue it. We merely wrap it around the latex and let time do the work of adhering the batting to the latex. The wool fibers will twist in to the latex in about 3 months, leaving it gripping the latex. Wool batting is not sticky like Dacron batting would be, so even without an inner case, the latex wrapped in wool will slip into the outer case easily. The batting still may be removed if desired, but it will leave behind small fibers in the latex.
How you wrap the natural latex cushion is up to you. Some choose to wrap the entire piece of foam, top and bottom, front and back, sides. Some choose to wrap just the noticeable areas, the front, the top and bottom. This minimal wrap focuses the batting where it will be most useful. It is called a bookwrap.
DIY or FULL SERVICE
We can be a full service shop. We can cut the latex to your dimensions, sew the cases, and even wrap the latex with wool batting and the stuff the case for you. If you want to DIY the batting and stuffing the case part, you will save yourself a little bit of money as our sewing room is out of state and our Indiana supply room would have to ship your supplies to our MN supply room. Why out of state? When I moved to Indiana, I couldn’t let go of my seamstress in MN as she is too creative and detailed of a sewer to leave behind. Besides our tickings and pillow cases, she sews alterations, crafts and general upholstery projects like slip covers and cushion cases.
