What Drives Cost Per Mattress: Building a Defensible Foam and Bedding Quote

A cost breakdown for mattress and foam assembly: what each dollar of a unit is made of, how to build a quote that survives scrutiny, and the estimating traps that erode margin.

Material is the largest slice of a mattress cost, typically 55 to 68 percent of factory cost, and foam plus springs dominate it. Price foam by the board foot from density: a 1.8 lb polyfoam at 1.05 dollars per board foot across 22 board feet of comfort layers is 23.10 dollars, while a pocketed queen coil unit runs 34 to 48 dollars depending on coil count. Fabric adds a knit panel at 4.20 dollars per yard times 2.5 yards, or 10.50 dollars. Use the Cost Per Mattress calculator to roll foam, coil, fabric, and trim into one material line before you layer labor on top.

Never quote gross material; quote material adjusted for yield loss, because the scrap is real money. If foam cut yield is 79 percent, the 23.10 dollars of usable foam actually consumed 23.10 divided by 0.79, or 29.24 dollars of purchased foam. That 6.14 dollar gap per unit is 2,456 dollars across a 400 unit run. Fabric at 26 panels from a 58 yard roll leaves 0.28 yards remnant per roll, another 1.18 dollars of loss per roll spread over units. Pull the loss factors from the Foam Cut Yield and Fabric Roll Yield calculators so your material line reflects what you actually buy.

Direct labor is priced in minutes, then converted at a fully loaded rate. At 14.2 minutes per mattress and a loaded rate of 28 dollars per hour, labor is 14.2 divided by 60 times 28, or 6.63 dollars per unit. Watch the loaded rate: a 19 dollar base wage carries payroll tax, benefits, and paid time that push it to roughly 27 to 30 dollars, so quoting at base understates labor by 40 percent. The Labor Per Mattress calculator gives you the minute basis; multiply by the burdened rate, never the wage on the pay stub.

Machine time is an allocation, not a wish. Charge each unit for the press, quilter, and coiler seconds it consumes at the equipment cost rate. A roll-pack press at 95 seconds per unit, with a machine rate of 42 dollars per hour covering depreciation, power, and maintenance, adds 95 divided by 3,600 times 42, or 1.11 dollars per unit. Quilting at 3.47 panels per minute on a 55 dollar per hour machine rate adds 0.26 dollars. Small per-unit, but across 90,000 units a year the press line alone allocates near 100,000 dollars that must land somewhere in the quote.

Adhesive and consumables are easy to underquote because they hide in aggregate. At 187.5 grams per mattress and web adhesive at 5.80 dollars per kilogram, glue is 1.09 dollars per unit, and the 20 percent overspray is already baked into that draw. Add tape edge thread, staples, law tags, and corner guards at roughly 0.85 dollars combined. Confirm the adhesive figure with the Adhesive Usage calculator, because a coverage assumption 1 gram per square foot too low understates glue cost by about 22 percent on a laminated build.

Scrap is a credit, not just a cost, and forgetting the recovery inflates your quote and loses bids. Trim foam has salvage value: 6.5 pounds of offcut per unit at 0.22 dollars per pound rebond value returns 1.43 dollars per mattress. Over 90,000 units that is 128,700 dollars of recovered material that should reduce net material cost. The Scrap Foam Value calculator converts offcut weight and grade into recovery dollars so your net material line is defensible rather than conservative to the point of losing work.

Overhead and changeover round out the fully burdened cost. Apply factory overhead as a rate on direct labor or machine hours, commonly 120 to 180 percent of direct labor, so a 6.63 dollar labor line carries 7.96 to 11.93 dollars of overhead. Changeover erodes it further: a 22 minute SKU changeover at 12 idle operators on a 28 dollar rate is 123 dollars of lost labor per change, spread thin on a 400 unit run but brutal on a 40 unit specialty batch. The SKU Changeover Time calculator lets you amortize that idle cost across true batch size.

The most common quoting failure is costing at planned volume while running at batch volume. A quote built on 400 unit runs looks healthy at 6.63 dollars labor, but a 60 unit boutique order carries the same 22 minute changeover and setup scrap over 60 units, lifting effective labor and overhead per unit by 30 to 45 percent. Always quote small runs on their own basis, add a minimum lot charge near 250 to 400 dollars, and validate the full stack in the Cost Per Mattress calculator so margin survives the mix, not just the flagship SKU.
