What does AquaShield Mattress Underlayment do?

AquaShield Mattress Underlayment decreases moisture by increasing airflow under your mattress. It slightly elevates the mattress from the platform to allow warm air to circulate underneath and reduce condensation, mold, mildew and dampness in RVs and other compact sleeping spaces.

Is AquaShield pre-cut to fit my RV mattress?

Yes. Each AquaShield underlayment from AB Lifestyles is pre-cut to match the size and shape of your bed, including RV mattresses, bunks and dinette cushions. It is made slightly smaller than the mattress dimensions so it does not interfere with fitted sheets or bed-making.

Will I feel AquaShield under my mattress?

No. AquaShield is designed to be undetectable in normal use. It adds airflow beneath the mattress but does not change the way the mattress feels on top.

Can AquaShield help prevent mold and mildew under RV mattresses?

Yes. By creating an air gap between the mattress and the solid platform, AquaShield reduces trapped moisture and condensation that often occur in RVs and Airstreams, helping limit mold and mildew growth.

What is AquaShield made of?

AquaShield is made from a 0.75 inch thick industrial-grade woven polymer material bonded to a breathable fabric. It is lightweight, flexible, durable and remains effective in cold temperatures.

How strong is AquaShield Mattress Underlayment?

AquaShield has been tested to withstand up to 990 pounds of dispersed weight on a twin-size mattress with less than 2 percent surface compression. Larger sizes can support more total weight and are designed not to collapse or flatten over time under normal use.

How do I install AquaShield?

For twin sizes, place the single pre-cut piece directly on the bed platform and set the mattress on top. For larger sizes, join the two pre-cut pieces with the included zip ties, lay the assembled underlayment on the platform and then replace your mattress or cushions. No tools or adhesives are required.

Can AquaShield be trimmed for unusual mattress shapes?

Yes. AquaShield can be trimmed with scissors for special corners, curves or radiused edges. The material cuts cleanly and maintains its structure after trimming.

Is AquaShield easy to clean and maintain?

AquaShield is low maintenance and can be cleaned with soap and hot water or with steam as needed. It does not absorb moisture and dries quickly after cleaning.

Where can AquaShield be used besides under RV mattresses?

AquaShield can also be used under RV cushions and dinettes, in underbelly storage compartments, under pet beds, in living quarter horse trailers, boats, semi trucks, aircraft, mobile homes, storage buildings, garages, coolers and metal containers to promote airflow and help reduce moisture and rust.
