We suggest applying baking soda to the soiled area, let stand about 15 minutes, vacuum and repeat as needed. Air the product out as much as possible.

We do not recommend applying liquids to the product. Applying liquids may stain the fabric and make the soiled area worse. Moisture or chemicals applied directly to the mattress can cause premature breakdown of the foam and damage the product.

In order to protect your mattress from stains and spills, we highly recommend using a mattress protector. This will also help with the overall health and lifespan of your mattress.


Comfort is something that should endure day after day. And we know a thing or two about lasting quality! Serta has blazed the trail in comfort since we introduced our first Perfect Sleeper® mattress in 1931.

We build Serta mattresses with the highest quality materials to give you years of outstanding comfort and support. All Serta mattresses are designed and assembled in the USA, leveraging Serta’s 85 years of manufacturing expertise.

I'll never buy a bed anywhere else! Affordable, friendly, and SO easy to work with! I've purchased maybe 5 mattresses now from these folks. The owner is often standing right there at the desk. They delivery, set-up your frame, etc. So wonderful and personable and real. No nonsense. How a VT-owned business should be.

- Ginger Vieira

This store is run by a young husband and wife with a 3 1/2 yr old kid who plays quietly behind the counter. When I entered, they greeted me but didn’t bum-rush me, which would have been annoying. Once I approached them, they were helpful, knowledgeable, and was able to get me exactly what I wanted and then through in a small discount.

- James D.

Just got our bed from Vermont Mattress Depot yesterday. I had the mattress delivered the very next day! They were courteous from beginning to end. The delivery guys were super friendly and careful. We have a tiny upstairs apartment and they were able to navigate our narrow hallways with ease! Speaking from experience, in all my 36 revolutions around the earth, this has been by far the best night sleep.
