Sofa Cushion Foam Cut To Size

Sofa cushion foam is upholstery padding made from polyurethane foam, cut to fit furniture cushions. It provides soft, comfortable support. “Sofa Cushion Foam Cut to Size” allows custom-fitting cushion foam to sofas and chairs. Tailored foam ensures a tight, professional fit without gaps.

Sofa cushion foam cut to size is available at upholstery shops. It’s cut to match measurements then wrapped before inserting into cushion covers. Custom-cut foam helps cushions keep their shape and give even support.

What is Sofa Cushion Foam?

Sofa cushion foam, also called upholstery foam, is padding made from polyurethane foam. It comes in different densities and levels of firmness. Low density foam is soft and allows more body impression, while high density foam is extremely firm with little give. Medium density foams offer a balance of comfort and support.

The thickness of the foam also impacts its feel. Thinner foam conforms more closely to the body, while thicker foam provides more cushioning. Cushion foam can be purchased in basic shapes like blocks, rolls and sheets. It can also be custom cut to specified dimensions. Upholstery shops have the tools to cut foam to the exact size and shape required.

The Benefits of Getting Foam Cut to Size

The Benefits of Getting Foam Cut to Size

Getting sofa cushion foam cut to your specifications offers several advantages compared to using standard size blocks of foam.

Tailored Fit

Foam cut to match the dimensions of the furniture frame allows for a tight, gap-free fit. There will be no gaps between cushions or loose areas that could cause sagging. Custom cut cushion foam hugs the furniture frame for a clean, tailored look.

No Trimming Needed

With pre-cut blocks of cushion foam, excess trimming is often required to get the foam to fit into the furniture frame. The cutting and trimming process wastes material and time. Getting the foam cut to the measurements needed means no trimming is required. The cushion foam will fit perfectly as soon as it is placed into the frame.

Even Support

Foam cut to size allows for full surface contact between the cushion and furniture frame. This prevents uneven support. Pre-cut foam often leaves gaps that can result in certain areas feeling too soft or too firm compared to other areas. Custom cut foam provides consistent comfort and support across the entire seating surface.

Better Shape Retention

Foam cut precisely to dimensions is less likely to become misshapen compared to foam that has been squeezed into place. A tight fit prevents the foam from shifting and deforming over time. Cushions maintain their shape rather than flattening or developing lumps and gaps.

Professional Results

Getting sofa cushion foam cut to specifications yields a polished, professional look. The cushions have a tailored appearance, as if they were made just for that furniture. Custom cut foam also makes it easier for do-it-yourselfers to achieve furniture shop quality results.

How Foam is Cut to Size

Upholstery supply shops use a few different tools to cut cushion foam to size:

  • Electric Knife: An electric carving knife allows for precise cuts through foam. The serrated blade creates a smooth edge.
  • Hot Wire Cutter: This tool uses a heated wire to melt through foam for accurate cuts. No blade makes this a safe option.
  • Pattern Templates: Custom templates matching furniture dimensions can guide perfect cuts. Templates are laid on the foam then followed with cutters.
  • Computer-Guided Cutter: Advanced machines allow entering exact measurements into a computer which then guides automated cutting for precision results.

Getting Measurements for Cut Foam

Getting Measurements for Cut Foam

To get sofa cushion foam cut to size, upholstery shops need a few key measurements:

  • Cushion length and width
  • Cushion height/thickness
  • Height from floor to top of cushion
  • Any non-square angles or irregular shapes

The most accurate way to get measurements is to remove cushions from the furniture and measure directly. Use a cloth measuring tape to get dimensions. For non-square angles, trace the shape onto paper to create a template.

If removing cushions isn’t an option, measure the furniture frame openings carefully with a tape measure. Add about 1/2 inch to the length and width measurements to allow foam to fully expand into the openings.

Always measure each individual cushion space rather than assuming equal dimensions. Write down measurements to provide accurate numbers for cut foam.

Placing the Cut Foam in Cushions

Once cushion foam has been cut to specifications, it can be inserted into cushion covers. First, wrap the cut foam with muslin or a thin layer of dacron padding. This helps protect the foam from damage. Align the foam precisely within the marked cushion opening on the furniture frame.

Check that the foam expands to completely fill the space without leaving gaps. It may take applying some pressure to get the foam to fully seat within the opening. Use a flat scraper tool to smooth and shape the foam if needed. The foam should fit snugly while allowing the cushion cover to go on smoothly.
