Short answer
Yes, when the bed has been on the floor, a solid platform or in storage, after a move, or when there's a musty smell. The underside collects dust, moisture and debris from under the bed, and a top-only cleaning doesn't reach it. Our underside treatment adds HEPA vacuuming, low-moisture dry vapor steam and UV-C to the bottom and is +$50–$75 per mattress.

HEPA vacuuming, enzyme treatment for organic odor, dry vapor steam and UV-C. We recommend cleaning twice a year.
Most cleaning treats the top because that's where you sleep. But the bottom is where moisture settles and where dust from under the bed collects.
When the underside matters
- Floor beds and solid platforms, where airflow is limited (damp undersides).
- Musty smell when you lift the bed (musty smell).
- After a move or storage (after storage; after moving).
- Used mattresses, where you don't know the history (cleaning a used mattress).
- Pets and kids who spend time under the bed.
What underside treatment includes
We flip or stand the mattress and give the bottom the same sequence as the top: HEPA vacuuming of the fabric and seams, low-moisture dry vapor steam, UV-C light treatment and a moisture check before we leave. It's +$50–$75 per mattress on top of the regular cleaning.
Can every mattress be flipped?
Many modern mattresses are one-sided, which means you shouldn't sleep on the bottom, not that it can't be cleaned. We handle the turn carefully and follow the maker's care guidance (why construction matters).
Don't forget what's under it
Clean the frame, slats or box spring while the mattress is up (cleaning slats and frames; box springs).
How we clean what you can't see
This section is our view. Every Sleep Sanitation visit starts with a nose-and-eyes inspection to find where the odor actually lives, then HEPA vacuuming, enzyme treatment on organic odor, low-moisture dry vapor steam from our Italian-made Vapor Clean machines, UV-C light treatment and a moisture check before we leave. Underside treatment, for the side that faces the floor or frame, is +$50–$75 per mattress. The first mattress is $199 Fall 2026 special (regularly $249), any size. We recommend cleaning every mattress twice a year so odor never gets a head start. Not sure what your bed needs? Take the 60-second mattress quiz, or schedule your cleaning.
