Clean your Tempur-Pedic the right way: machine-wash the cover cold, never wet the TEMPUR foam, and use a peroxide-and-baking-soda treatment for yellow stains and urine.
A Tempur-Pedic mattress can last 10-12 years, but only if you clean it correctly. The single rule that matters most: TEMPUR® foam should never get wet. Machine-wash the removable cover, blot - never soak - any spill on the foam, and use baking soda for routine freshening. This guide walks through the cover wash, spot cleaning, urine and yellow-stain protocols, and the maintenance habits that protect your warranty.
Have a soft top layer or quilted surface? See how to clean a pillow top mattress from pee.
Strip every layer of bedding (sheets, mattress protector, pad). Open a window. Inspect the mattress for the small white care label sewn into the seam - older Tempur-Pedic models (pre-2018) sometimes have non-removable covers, and the wash steps below don't apply to those. If you're not sure, check Tempur-Pedic's own product-care page for your model.
Almost every Tempur-Pedic mattress sold since 2018 has a fully zippered, machine-washable cover. Unzip it from each corner and carefully pull it off the foam core. Tempur-Pedic recommends washing every 1-3 months.
While the cover dries, leave the foam exposed in a well-ventilated room. This is the perfect window to deodorize.
Use a hand vacuum or your upright's upholstery attachment. A soft brush head is critical - stiff bristles can pull at the open-cell foam. Vacuum the top, sides, and seams.
Don't use scented carpet powders - the perfume binds to the foam and you can't rinse it out.
If the spill is on the cover and you caught it fast, you can usually unzip and wash. If it has soaked through to the foam, follow this protocol - it's the closest you can come to "washing" TEMPUR material without voiding the warranty.
Heat is the silent killer here - Tempur-Pedic explicitly warns that direct heat can damage the TEMPUR formula. That includes electric blankets, heating pads, and hot dryer settings on the cover.
Yellow halos are oxidized body oils, sweat, and urine residue. Surface stains usually live on the cover, where you can launder them. Stains that bled through to the foam need the gentlest possible chemistry: hydrogen peroxide, dish soap, and baking soda.
Mix immediately before use - it loses fizz fast. Apply with a spray bottle or a clean toothbrush; do not pour it. Let it bubble for 5-10 minutes, blot with a dry towel, then air-dry fully. For deep urine accidents on the foam, see our dedicated memory-foam urine guide - the protocol there is what we'd use on a Tempur-Pedic, just slowed down to protect the warranty.
Tempur-Pedic mattresses are one-sided - never flip them upside down. The support layer underneath is firmer foam designed to stay on the bottom.
The single best upgrade you can make is a waterproof, breathable mattress protector. Tempur-Pedic sells a wet-safe model, but any high-quality protector that fits a 12-14" deep mattress will do - see our best organic mattress protectors guide for editor-tested picks. Add a washable mattress pad on top of the protector for sweat and skin oils. Keep bedroom humidity between 30-50% with a dehumidifier in summer; mold needs more than 60% RH to take hold inside foam.
No. Steam pushes hot moisture deep into the open-cell foam, which can degrade the TEMPUR material and trap humidity that grows mold. Tempur-Pedic explicitly warns against any wet cleaning of the foam itself.
No. The full cover unzips at the corners - pull it off completely before washing. Trying to spot-wash a still-zipped cover pushes water and detergent into the foam underneath.
Mix 1 cup 3% hydrogen peroxide, 3 tablespoons baking soda, and a drop of unscented dish soap. Apply lightly with a spray bottle or clean toothbrush, let it bubble for 5-10 minutes, blot with a dry towel, then air-dry fully. Test on a hidden corner first.
At least 24 hours with a fan running and the windows open. Re-covering damp foam is the fastest way to grow mildew. If you can still feel coolness on the surface with the back of your hand, it's not dry.
Routine vacuuming, baking-soda dusting, and washing the cover per the care label do not void the warranty. Soaking the foam, dry-cleaning the cover, or applying a heated drying tool can void it - the warranty specifically excludes damage from improper care.
Encase the entire mattress in a zipper-sealed bed-bug-proof cover for at least 12 months - Tempur-Pedic foam can't be heat-treated like a traditional mattress. For dust mites, the same waterproof protector you use for spills also blocks mite penetration; weekly hot-water washing of sheets does the rest.
