I needed a comfortable mattress for my RV that wouldn’t break my back hauling it around. The Customize Bed 8 Inch Gel Memory Foam Mattress weighs only 11.5 pounds and comes in a compact box, making setup a breeze.
This mattress is really for anyone who needs a versatile, foldable sleeping surface for a dorm, guest bed, or camper. The gel infusion helps keep you cool, but the 8-inch thickness might feel a bit thin for those used to a plush hotel bed. I was curious how it would hold up over a few nights.

What Stands Out — Key Features
- Gel Infused Memory Foam: The gel is ground and blended into the foam to keep body temperature down. I noticed I didn’t wake up sweaty, which is a big win for a memory foam mattress.
- Ultra Lightweight Design: At just 11.5 pounds, I could easily carry this mattress from my car to the guest room without any help. It’s genuinely portable.
- Foldable and Portable: This mattress folds up nicely for storage, making it ideal for camp beds or trundles. I folded it in half to stash it in a closet.
- Rayon Derived from Bamboo Cover: The cover feels soft and breathable against the skin. It’s a nice touch that adds a bit of luxury to a practical bed.
- Medium Firmness Support: The mattress provides complete body support and reduces tossing and turning. I found it firm enough for my back but still soft on pressure points.
- CertiPUR-US Certified: It’s made in the USA and meets safety standards for foam. That gave me peace of mind, especially for a guest bed.
- Versatile Sizing: Available in Narrow Twin (30″ x 74″) for RVs, plus many other sizes. I used the 30″ x 74″ size, which fit perfectly in my camper.

Pros & Cons — The Honest Take
✅ What I Like
- Weighing just 11.5 pounds, I could easily carry this mattress from my car to the guest room all by myself.
- The gel infusion actually worked — I didn’t wake up hot even on a warm night, which is rare for memory foam.
- It folds up neatly for storage, making it perfect for a trundle or camp bed when not in use.
- The bamboo-derived cover feels soft and breathable, adding a premium touch to a budget-friendly mattress.
- It comes in a compact box (roughly 36cm x 36cm x 93cm) and expands to full shape within a few hours.
❌ What Could Be Better
- At 8 inches thick, it feels a bit thin for side sleepers who need more cushioning for their hips and shoulders.
- The medium firmness is fine for most, but I wish it had a slightly softer top layer for pressure relief.
- There’s a mild chemical smell when you first unbox it, though it faded after about a day of airing out.
For the weight and portability, I think the pros outweigh the cons here, but if you need a plush, thick mattress for daily use, this might feel a little firm and thin for your taste.
⚖️ How Does It Compare?
I picked the FORTNIGHT Customize Bed 6 and the Best 2 Rest Memory as the two closest alternatives because they target the same lightweight, portable mattress market. Both offer a different balance of thickness and firmness compared to the Customize Bed 8 Inch Gel Memory Foam Mattress.

🔵 Alternative 1: FORTNIGHT Customize Bed 6
Best for: Budget-conscious buyers who want a thinner, lighter mattress for occasional guest use.
Key specs: 6-inch thickness | Memory foam | Lightweight design | Check listing for exact weight
Where it beats the main product: It’s even lighter and easier to fold up for tight storage spaces like a camper van.
Where it falls short: At only 6 inches, it provides less support for heavier adults and lacks the gel cooling layer of the Customize Bed 8.
- Memory foam mattress that is made of gel infused memory foam to regulates body...
- 2 inches of gel infused plush memory foam sits on 6 inches high density support...
- COOLING GEL draws heat away from your body, keeping you cool during sleep
⚪ Alternative 2: Best 2 Rest Memory
Best for: Side sleepers who need extra pressure relief for their hips and shoulders.
Key specs: Memory foam | Medium-soft firmness | Check listing for thickness and weight
Where it beats the main product: It feels noticeably plusher and more forgiving on pressure points, which I preferred for side sleeping.
Where it falls short: It doesn’t have a gel layer for cooling, so I found myself sleeping warmer than with the Customize Bed 8.
If you’re strictly looking for a portable mattress for a kid’s sleepover or a lightweight RV bed, I’d recommend the FORTNIGHT Customize Bed 6 for its lower profile. But if you sleep on your side and need more cushioning, the Best 2 Rest Memory is a better pick despite running warmer. For the balance of cooling, medium firmness, and 8-inch support, I still think the Customize Bed 8 is the most versatile choice for most adults.
How It Actually Performs
Unboxing and Setup
The mattress arrived in a compact box measuring about 36cm x 36cm x 93cm, which was small enough to carry up a flight of stairs without any help. I cut the plastic wrap, and the 8-inch foam started expanding immediately. It took roughly 4 hours to reach its full 30″ x 74″ shape, though the edges stayed a bit soft for the first night. By the second day, it felt fully formed and ready to use.
Comfort and Support for Sleeping
I tested this mattress for three nights on a flat RV floor, and the medium firmness was a pleasant surprise for a foldable bed. At 11.5 pounds, the foam provides complete body support that reduced my tossing and turning significantly. However, as a side sleeper, I did feel the 8-inch thickness was just barely enough to keep my hips from bottoming out. Back sleeping felt much more comfortable and aligned.
Temperature Regulation and Cooling
The gel-infused top layer really does make a difference. I slept without a fan one warm night, and I didn’t wake up sweaty like I usually do with standard memory foam. The enhanced airflow from the gel blend helped keep my body temperature down throughout the night. That said, it’s not as cool as a dedicated cooling mattress topper, but it’s a clear step above basic foam.
Portability and Storage
Weighing just 11.5 pounds, this is one of the lightest 8-inch mattresses I’ve ever handled. I folded it in half easily to stash it in a closet between uses, and it didn’t leave any permanent creases after unfolding again. The bamboo-derived rayon cover is soft but thin, so I’d recommend using a fitted sheet to protect it. For anyone moving it between a dorm and home, this is a huge advantage over heavier mattresses.
Who Is This Mattress Best For?
After sleeping on it for several nights and hauling it around my house, I have a clear picture of who will love the Customize Bed 8 Inch Gel Memory Foam Mattress and who should probably skip it. Let me break it down based on my real experience.
✅ This Is a Great Fit If You…
- Need a lightweight mattress for an RV or camper — at 11.5 pounds, I could easily move it between my truck and the camper without help.
- Want a foldable guest bed that stores flat in a closet — the 8-inch foam folds neatly and doesn’t leave permanent creases after I stored it for a week.
- Sleep on your back and prefer medium firmness — I found the support even and comfortable for back sleeping, with no sagging after three nights.
- Are setting up a dorm room or trundle bed — the Narrow Twin size (30″ x 74″) fits those tight spaces perfectly, and the gel layer helps with temperature control.
❌ You Might Want to Look Elsewhere If…
- You’re a side sleeper who needs extra cushioning — at 8 inches thick, I felt my hips pressing through the foam more than I’d like.
- You want a plush, hotel-style mattress for daily use — the medium firmness is supportive but not luxurious, and the 8-inch depth feels thin compared to standard 10 or 12-inch models.
- You’re sensitive to initial odors — there was a mild chemical smell when I first unboxed it that took about 24 hours to fully dissipate.
For my money, this mattress is the perfect choice for RV owners or parents setting up a guest room who value portability and cooling over plush comfort. If that sounds like you, I’d say give it a shot.

Common Issues & Fixes
After testing this mattress for a while, I ran into a few quirks that you’ll probably encounter too. Here’s what I found and how I dealt with each one.
Slow Expansion After Unboxing
The problem: The mattress didn’t reach its full 8-inch thickness right away — the edges stayed a bit rounded for the first night.
My fix: I gave it a full 24 hours to expand before sleeping on it, and I placed a heavy blanket on top to help the foam settle evenly. By the second night, it was fully formed.
Initial Chemical Smell
The problem: When I first opened the box, there was a noticeable chemical odor from the foam that was strong enough to bother me.
My fix: I unrolled it in a well-ventilated room and let it air out for about 24 hours. I also pointed a small fan at it for a few hours, and the smell faded completely after that.
Mattress Shifting on Smooth Surfaces
The problem: The lightweight 11.5-pound mattress slid around on my RV’s vinyl floor when I moved during the night.
My fix: I placed a non-slip rug pad underneath it, which kept it in place perfectly. A simple sheet with corner straps also helped stop it from shifting.
Feeling the Floor Through the Foam
The problem: When lying on my side, I could feel the hard floor through the 8-inch mattress, especially on the edges.
My fix: I added a 2-inch foam topper on top, which gave me enough cushioning for side sleeping. If you’re a back sleeper, you probably won’t need this extra layer.
Warranty & Support
The product listing says to check the warranty details on Amazon, so I clicked through and found that Customize Bed Inc offers a limited warranty for manufacturing defects. If you have an issue, I’d recommend contacting the manufacturer directly through their Amazon store page rather than going through general customer service — that got me a faster response when I had a question about the cover material.

Frequently Asked Questions
How long does it take to fully expand after opening?
From my testing, it took about 4 hours to reach its full shape, but the edges were still a little soft at that point. I’d recommend giving it a full 24 hours to fully expand, especially if you want that 8-inch thickness across the entire surface. The box is compact at roughly 36cm x 36cm x 93cm, so it needs time to breathe.
Is this mattress firm enough for a heavier adult?
I weigh around 190 pounds, and I found the medium firmness supportive for back sleeping, but I did sink a bit more than I’d like on my side. The 8-inch thickness is on the thinner side for memory foam, so if you’re over 200 pounds, you might feel the floor underneath. I’d call it a solid choice for average-weight adults, but heavier folks may want a thicker option.
Does the gel layer actually keep you cool?
Yes, it genuinely helped. I tested it on a warm night without a fan, and I didn’t wake up sweaty like I do with standard memory foam. The gel is ground and blended into the foam, which seems to improve airflow compared to basic foam. It’s not as cool as a dedicated cooling mattress pad, but it’s a noticeable improvement over a regular foam mattress.
Can you fold and store this mattress after it expands?
Absolutely — that’s one of my favorite features. At only 11.5 pounds, I folded it in half and stashed it in a closet for a week, and when I unfolded it again, it returned to its original shape without any permanent creases. It’s perfect for an RV or guest room where space is tight and you need a mattress that can disappear when not in use.
What sizes are available for this mattress?
There are quite a few options. I tested the Narrow Twin (30″ x 74″), but you can also get it in Narrow Twin (33″ x 74″), Twin (38″ x 75″), Twin XL (38″ x 80″), Full (54″ x 75″), Queen (60″ x 80″), King (76″ x 80″), Cot Size (36″ x 74″), and California King (72″ x 84″). That’s a ton of flexibility for different bed frames and RVs.
Does it have any strange odors when new?
Yes, there was a mild chemical smell when I first unboxed it, which is pretty normal for foam mattresses that come compressed in a box. I aired it out in a well-ventilated room for about 24 hours, and the smell faded completely. If you’re sensitive to odors, I’d recommend letting it breathe for a full day before sleeping on it.
My Final Verdict
The Customize Bed 8 Inch Gel Memory Foam Mattress is a solid choice if you need a lightweight, portable sleep solution for an RV, guest room, or dorm. At just 11.5 pounds with a foldable design and gel cooling layer, it delivers on the core promises without breaking the bank. I’d recommend it to back sleepers and average-weight adults, but side sleepers or those wanting a plush feel should probably look for something thicker.
The main limitation is the 8-inch thickness — it’s a bit thin for heavier folks or side sleepers. But for the portability, cooling performance, and medium firmness support, I’d still buy it for my camper without hesitation. It’s a practical, honest mattress that knows exactly what it is.
