Review: Comfortable and great quality - Excellent product! Very soft and comfortable. Exactly what I was lookig for. It folds perfectly and comes with a mattress protector. The foam is thick enough to offer a pleasant rest. I am happy with the my purchase and recommend it one hundred percent.
Review: Yep !!! The RV sofa has a new and better mattress - I bought this specifically to replace the spring mattress that came with our sofa bed in our 5th wheel. The queen size fits well and expanded to the full advertising size. The metal frame and bars are not a problem anymore. Originally I had put a 2” memory foam topper on the springs but have been unhappy with that setup as the metal frame was still a nuisance. Furthermore, the extra mattress thickness made folding the bed in a problem. This mattress fold in properly. I’m 74 and 6’4” 245 and while I do not intend to use this as a primary sleeper, I could, I believe, use this sofa in a pinch without a problem. My wife agrees that we made a wise choice in this mattress and she feels comfortable using it as a secondary bed. No complaints. Hope this helps someone in there decision

## Features

- Our bi-layered mattress combines a 3in firm polyurethane foam base with a 1.5in soft memory foam topping that slowly conforms to your body contours and still provides adequate support that’s compatible with most folding couch bed frames and is also used for boat, camper & RV.
- Rough night? Your mattress cover might be responsible. The jacquard waterproof soft cover included on our mattress is so soft and comfortable that you might skip the fitted sheets. It’s also ventilated to allow body heat to dissipate. Sleep soundly, not stifling.

### ⭐⭐⭐⭐ Measure your frame
*by M***N on June 28, 2023*

Measure your frame! We have a queen size and this mattress is too small -- I didn't measure my frame beforehand and trusted the "queen size" so I'm not deducting from the rating because that was my fault. This is just a word of caution to everyone else. Expensive mistake. That being said, it is significantly more comfortable than the mattress that came with the bed. I can feel where the bar is, but it is very minimal and so much better than before. I think this is a great purchase and it was worth the money. It is a tight squeeze to fold back up, but it does fold back up.
