ZINUS Ultima – The Best RV Mattress for Back Pain

For years, I struggled with lower back pain that was only worsened by the poor mattresses in my RV. Any bumps in the road felt like knives in my spine. I tried multiple mattresses hoping to find relief, but nothing worked. That’s when I discovered the ZINUS Ultima memory foam mattress. What drew me to it was its innovative design tailored specifically for RV beds.

Over several camping trips since, my back pain has greatly reduced. I’m now even able to hike and bike each day without discomfort. If you suffer from back pain, especially in smaller sleeping spaces, I highly recommend trying out this mattress. Let’s find out why I consider this one to be the best RV mattress for back pain.

The Mattress Overview

The ZINUS Ultima is an excellent option for the campers suffering from back pain. It provides extra support without compromising the comfort factor. While still soft on top, the mattress feels quite firm underneath.

That’s because it has multiple zoned layers that provide different levels of support. Softer layers cushion pressure points, while firmer layers properly align your spine. The firm mattress has an impressive 10-inch thickness that provides the necessary support for a good sleep, even in the confines of an RV.

ZINUS Ultima Mattress Construction

At the core of the Zinus Ultima mattress is a layer of high-density foam called Z:Base foam. It provides the structure and support foundation for the entire mattress. On top of that is a layer of softer foam called Z:Comfort foam, which works to cushion your body and relieve pressure points.

Then comes the star of the show—a layer of green tea infused memory foam, which the company labels as Z:Cool memory foam. All these different layers work harmoniously together. The Z:Base gives sturdiness and support. The Z:Comfort foam cushions and contours. And the cooling memory foam on top shapes around your body perfectly. 

The mattress uses Certipur-US certified foams that are free of ozone depleters, mercury, lead, and other heavy metals. I feel good knowing what I’m sleeping on is made of non-toxic materials. 

ZINUS Ultima Mattress Performance

So, what makes this mattress a good choice for people with back pain? Let me explain the features that I consider its selling points:


While many foam beds are too soft and cause the lower back to sink in, and others are too hard and create pressure points, the Ultima mattress has a balanced firmness. 

When I first lay down, the top layer of green tea-infused memory foam immediately contours to my body, cradling my shoulders and hips. However, unlike some beds, I never feel as though I’m sinking in too deep. The foam supports the natural curves of my body without allowing pressure to build up. Even after sleeping for 8 hours, I can roll over or get up without any difficulty, which tells me the foam is compressing just the right amount.

Motion Transfer

One aspect I really appreciate about this mattress is how little motion transfer I experience. As a side sleeper who sometimes tosses and turns through the night, I need a mattress that absorbs movements rather than allowing them to ripple across the surface. With this mattress, I’ve found my partner can get in and out of bed or shift positions without it significantly impacting my sleep. 

The tightly woven blend of memory and comfort foams does an amazing job of isolating motion. Even bigger movements, like if one of our dogs hops up on the bed, are dampened very well. I don’t feel like I’m sleeping on a trampoline every time someone moves on their side. 


The foam layers of this mattress feel responsive. What I mean is that the memory foams quickly take on the contours of my body but don’t retain an imprint after I get up. As soon as I roll over or move positions, they bounce back to evenly distribute my weight again.

This level of responsiveness is welcoming whether I’m trying to sleep on my back, side, or stomach. The foam truly hugs my curves without allowing problem areas to sink excessively into the mattress. I wake up feeling well-rested instead of stiff. 

Temperature Control  

As someone who tends to get warm when sleeping, I was happy to discover how well this mattress keeps me cool, even on summer nights. The green tea and charcoal-infused memory foam make an incredible difference in ventilation.

The tree extracts in particular are superb for drawing moisture away from the body and promoting airflow. On multiple occasions now, I’ve woken up sweat-free when normally I’d be drenched. The foam doesn’t retain heat like other memory foams tend to. It absorbs it instead. 


The Ultima is a durable mattress, no doubt about that. It shows no visible signs of wear and tear even after putting it through regular use and some harsher RV conditions. The seams and edges remain well-constructed. Regular vacuuming removes lingering odors as needed. 

It just seems like this mattress can withstand plenty more years of action. Getting this level of longevity out of a bed at such an affordable price is quite amazing.

Why Is This The Best RV Mattress for Back Pain?

I rate the ZINUS Ultima highly for people with back pain because my morning aches and pains are a thing of the past after switching to it over a year ago. It supports my spine at every point. The green tea-infused foam contours to my curves for a weightless feel without sagging. My back has room to rest in a natural alignment. No more rolling over to find a new sore spot!

Whether sleeping or getting up, my back doesn’t hold me back anymore, thanks to this mattress. Its supporting foam and natural spine alignment make it a champion against achy nights.

My husband and I love this mattress! We were worried at first when we opened it because it look so thin, but it expanded nicely and is very comfortable! It’s firm enough to give good support, yet malleable enough to adapt to your bodies shape. At no point, do you feel the bed frame through the mattress.
I’m 5 months pregnant and I sleep so well now! My back and hips are really well supported and actually this mattress has completely relieved the pain in my hips while I sleep. Great mattress, especially for the price! 10/10 would recommend.

I had a mattress that came with my RV that was horrible. After sleeping on it for 6 months there was a huge indentation where my hips laid (I am a side sleeper). I woke up with severe back and hip pain. I researched queen short mattresses online and they were $500 and up. I came across the Zinus 8 inch memory foam queen short mattress on Amazon for less than $200. I read the reviews which for the most part were great, so I purchased this mattress and could not be happier. The first night I slept for 10 hours!! I now wake up with no hip or back pain. I love this mattress and can highly recommended it.

I have degenerative disc disease and have been sleeping on the cheap mattress my travel trailer came with. After a month I decided it was too much and saw this mattress and took a chance. This is a night and day difference. I can feel the support in my lower back and my pain has been fading. I definitely recommend this mattress to replace the one your RV came with.

My husband and I both have bad backs. Our problems are not the same and we both like this mattress. I’m not going to exaggerate and say it’s like sleeping on a cloud or all of our problems while sleeping are gone! They aren’t gone for me. My arms still hurt and then my fingers get numb and tingly or my hips will still ache causing pain all the way to my knees and sometimes ankles. I will say that I don’t have to drag myself out of bed anymore. My lower back is not crippling me after being in bed all night. The bed is just firm enough to keep you from sinking into it. For me the mattresses you sink into are awesome when you first get in, but then I can barely turn over and my lower back feels like it is swayed when I’m on my stomach. OUCH! This mattress isn’t too firm though. I don’t feel like I’m sleeping on a covered rock. We both are satisfied with our purchase. We never expected it to take away all of our back problems. It’s a mattress, not a miracle. Our expectations were met and we sleep as comfortable as possible considering.

Wasn’t sure what to expect from a box mattress, but I knew our camper mattress had to go. I suffer with back, hip and leg pain. So I decided to give this matress a try after reviewing several. The set up was easy. There was very minimal smell and nothing bad at all. Went camping for 5 nights and every night was comfortable. I highly recommend this matress for a good night’s sleep.
