Perfect fit for RV king mattress. Great materiel. No cutting required. Highly recommended.

This was purchased as a proactive measure to help make sure we don’t face any mold issues in our travel trailer. We have not had any issues in the past but I’d rather err on the side of caution. It seems to be well made and should work properly.

Simple to unroll and set up without cutting. Adds airflow under the mattress and prevents dampness from collecting. The elastic bands hold it in place even when moving around. Material feels strong and the mesh does what it should.

I got this mattress ventilation pad to use in my camper under my short queen mattress. It fit perfectly and was very easy to install. The material is thicker than I was expecting and seems to hold up pretty well. I don't know if these mattress pads actually work at keeping moisture down, but this one looks to be one of the better ones I've seen.I'm going to give this 5 stars, as the build quality seems good and strong, the pad is reasonably thick, and the fit was spot on!

I got this Ventilation Pad for my fifth wheel RV bed. This pad was very easy to setup and install with two people. I like that it goes under my mattress and helps with ventilation. The pad is very flexible and light weight. I like that the material is soft and fits well on my RV bed frame. I also like that it goes under my mattress and doesn't slide around on travel days.

This review is for the Safoner RV Mattress Underlay in the Short Queen (74'' x 60'') size, which we've installed in our 2020 Grand Design Imagine 2500RL. As RV travelers who primarily explore the drier Western states (often documented on our YouTube channel), under-mattress condensation hasn't been a major issue for us yet. However, with plans to venture towards the East Coast, especially during cooler and more humid seasons, we wanted a proactive solution, and this underlay seems perfect for that purpose.Build Quality & Design:The underlay appears very well constructed. It's made from a 3D breathable mesh material designed to promote airflow, and importantly, it has nicely bound edges, which gives it a clean finish and should prevent fraying – a step up from some underlays that are just cut mesh. The elastic corner straps are a good feature and seem effective in holding the underlay securely to the bottom of the mattress.Fit & Installation:Installation was as simple as unrolling it and placing it under the mattress. For our setup, the Short Queen size was actually a good fit for our full-length queen mattress. This is likely because our RV bed platform is slightly shorter than the mattress itself, and the underlay effectively covered the entire platform area needing ventilation. It was ready to use right out of the box with no trimming required.Intended Benefit – Proactive Moisture Prevention:While we haven't yet put it to the ultimate test in sustained high-humidity, cool-weather camping (the conditions most likely to cause condensation under an RV mattress), this underlay seems like it will do exactly what it's designed for: create a crucial air gap to keep the underside of the mattress dry and prevent dampness or mildew. For us, it’s about peace of mind and preventing a problem before it starts as we travel to new climates.Conclusion:The Safoner RV Mattress Underlay appears to be a high-quality, well-thought-out product. It's easy to install, fits our needs well even with a slightly different mattress/platform combination, and the construction inspires confidence. For RVers looking to proactively combat under-mattress condensation, especially when traveling to varied climates, this seems like an excellent solution. We're very happy with it as a preventative measure.

This under mattress pad works well. It's slip resistant and keeps our mattress in place better than before. The bottom of the mattress and the top of the bed platform are both drier. It is quiet and doesn't make noise when you move on the mattress.We needed a short queen and it fits just right.Good value in an under mattress pad.
