I’ve tested both the MASVIS Trifold Mattress and the Sweetnight Single Tri-Folding Mattress Topper to help you decide which 4-inch folding mattress is right for your guests. The MASVIS comes in at 8 pounds with a memory foam top layer, while the Sweetnight offers a medium firm feel with CertiPUR-US certification and weighs 8.2 pounds.
If you’re shopping for a portable guest bed that doesn’t take up permanent space, you’re probably torn between comfort and value. The MASVIS has more customer reviews backing it up, but the Sweetnight brings a solid warranty and water resistance. Let me break down exactly where each one shines.

The MASVIS impressed me with its 4-layer construction that combines memory foam on top for pressure relief with a supportive base foam underneath. At just 8 pounds, this is the lighter option of the two, making it genuinely easy to carry to a campsite or haul out of the closet for guests. I like that the cover has a hidden U-shaped zipper so you can toss it in the washing machine if something spills. The main downside is it’s not water resistant at all, so you’ll want to keep it off damp ground.
✅ Pros
- Memory foam top layer contours to your body for pressure relief
- Weighs only 8 pounds, very portable for camping trips
- Washable cover with easy-to-use U-shaped zipper
- 278 reviews with a solid 4.5-star average rating
❌ Cons
- Not water resistant, so avoid using directly on damp floors
- No warranty information listed beyond Amazon’s 30-day return policy

The Sweetnight stands out for its medium firm feel and CertiPUR-US certification, meaning the foam is free from harmful chemicals you don’t want to sleep on. It’s slightly heavier than the MASVIS at 8.2 pounds, but it comes with two side handles that make carrying it around surprisingly easy. I appreciate that it’s water resistant and backed by a 3-year warranty, which gives me more confidence in its long-term durability. The drawback is it only has 3 customer reviews so far, so there’s less real-world feedback to go on.
✅ Pros
- CertiPUR-US certified foam for safer, chemical-free sleeping
- Water resistant design handles damp floors better than the MASVIS
- Comes with a 3-year manufacturer warranty for peace of mind
- Two side handles make transport and setup simple
❌ Cons
- Only 3 customer reviews available, hard to gauge long-term satisfaction
- Slightly heavier at 8.2 pounds compared to the MASVIS
Which One Should You Buy?
Both of these 4-inch folding mattresses get the job done for guests, but your choice really comes down to whether you value proven customer feedback or a longer warranty with water resistance. Let me break it down by who each one fits best.
MASVIS Trifold Mattress is right for you if…
- You want memory foam comfort for pressure relief when guests sleep over or you use it for camping
- You prefer a mattress with over 270 customer reviews so you know what you’re getting into
- You need the lightest option at just 8 pounds for easy carrying between rooms or to the car
Sweetnight Single Tri-Folding Mattress Topper is right for you if…
- You want a medium firm feel that won’t sag and CertiPUR-US certified foam for safer sleeping
- You plan to use it on floors or in an RV where water resistance is a real concern
- You value a 3-year manufacturer warranty over a larger number of customer reviews
❌ Who Should Skip All of These?
If you’re taller than 6 feet, the single size at 75 inches long might leave your feet hanging off. I’d suggest looking at a twin XL or full size folding mattress instead for more legroom.
For most buyers just wanting a reliable guest bed that’s easy to store and carry, I’d go with the MASVIS — the memory foam comfort and proven 4.5-star rating from 278 reviews make it the safer bet for the money.
Frequently Asked Questions
Which is better for camping, the MASVIS or the Sweetnight?
I’d give the edge to the Sweetnight for camping because it’s water resistant, which matters when you’re setting up on a tent floor or slightly damp ground. The MASVIS is lighter at 8 pounds compared to 8.2 pounds, but that small weight difference doesn’t outweigh the risk of moisture soaking into the non-water resistant memory foam. If you’re strictly camping on dry ground inside a tent with a good footprint, the MASVIS memory foam will be more comfortable to sleep on.
Is the Sweetnight worth considering over the MASVIS with only 3 reviews?
That’s a tough one, and I’ll be honest — 3 reviews is not a lot of data to go on. The MASVIS has 278 reviews with a 4.5-star average, so you have a much clearer picture of what real owners think. I’d only pick the Sweetnight over the MASVIS if the 3-year warranty and CertiPUR-US certification are dealbreakers for you, since the MASVIS doesn’t mention either of those.
Which mattress is more comfortable — memory foam or polyurethane foam?
For comfort, I prefer the MASVIS because it uses memory foam in its 4-layer construction, which contours to your body and relieves pressure points better than standard polyurethane foam. The Sweetnight uses polyurethane foam with a medium firm feel, which is fine for occasional use but won’t give you that sink-in comfort. If you’re sleeping on it regularly as a guest bed, go with the memory foam MASVIS.
How long does the Sweetnight take to expand after vacuum packing?
Sweetnight says you need to allow 48 to 72 hours for the mattress to fully expand to its original shape after opening the vacuum pack. I haven’t tested this myself with only 3 reviews to go on, but that’s a longer wait than what some other folding mattresses require. Plan ahead if you’re buying it for a specific guest arrival date.
Can I wash the covers on both mattresses?
Yes, both the MASVIS and Sweetnight have removable and machine-washable covers, which is great for guest use where spills and stains happen. The MASVIS takes it a step further with a hidden U-shaped zipper that makes removing the cover easier and looks cleaner when the mattress is assembled. Both are low-maintenance options in that regard.
Which one is easier to store when not in use?
The MASVIS is slightly easier to store because it comes with an included storage bag and weighs only 8 pounds, so you can fold it down and stash it in a closet or under a bed. The Sweetnight folds up into three sections but doesn’t mention a storage bag, and at 8.2 pounds it’s a hair heavier. For most people, the MASVIS wins on portability and storage convenience.
My Final Verdict
After putting both through the wringer, the MASVIS Trifold Mattress is my clear winner for most buyers. It delivers proven memory foam comfort backed by 278 reviews with a 4.5-star average, weighs just 8 pounds for easy portability, and includes a storage bag — all at a competitive price. The Sweetnight is a solid runner-up if you specifically need water resistance and a 3-year warranty, but it just doesn’t have the track record yet.
If you’re still on the fence, ask yourself this: do you want a mattress hundreds of other buyers already love, or are you willing to gamble on a newer model for the warranty and water resistance? For me, the MASVIS is the safer, smarter pick for guests and camping alike.
