The provided search results don't contain specific instructions for washing sofa cushions, so I'll answer based on general cleaning expertise.
That's a great question, and the answer is a classic "it depends." For many sofas, you absolutely can wash the cushion covers in the machine, but you have to check first to avoid a laundry disaster like shrinking or color loss.
The most important step is to find the care tag on your cushions. This tag has a cleaning code that tells you exactly how to treat the fabric. Usually, you'll see one of four letters. A "W" means it's safe to clean with water, making it a good candidate for the washing machine. "S" means you should only use a solvent-based cleaner, so do not put it in the wash. "W/S" means you can use either water or a solvent, but you should still proceed with caution. Finally, an "X" means vacuum only, so water is a no-go.
If your cushion covers have a "W" and are removable, you're likely in the clear. To wash them safely, zip them up completely and wash them on a gentle cycle with cold water and a mild detergent. It's best to wash all the covers at once, even the clean ones, to ensure any slight fading is uniform.
When it comes to drying, air-drying is your safest bet to prevent shrinking. If you must use a machine, choose the lowest heat or an air-fluff setting. A great trick is to put the covers back on the foam inserts while they are still just a little damp. This helps them stretch back into their original shape for a perfect fit.
