I’ve been testing two popular 4-inch Full size sofa bed replacement mattresses: the SUNYRISY Foldable Sofa Bed Mattress and the Schow Life 4 Inch Sleeper Sofa Mattress. Both measure 72 inches long by 53 inches wide, but they take completely different approaches to portability and comfort.
If you’re trying to decide between a truly foldable mattress you can stash away versus a more traditional sleeper pad with a non-slip bottom, this comparison is for you. I’ll break down exactly where each one shines so you can pick the right fit for your space.

This SUNYRISY mattress impressed me right out of the box because it actually folds into three sections, making it super easy to store or carry to the campsite. The memory foam does a solid job of aligning your neck and spine, and I love that the zipper cover is machine washable and breathable. Just keep in mind it arrives compressed and needs 12-24 hours to fully puff back up before you use it.
✅ Pros
- True trifold design lets you fold and store it easily
- Machine washable cover uses breathable 350D air layer fabric
- Memory foam conforms to your body for neck and spine alignment
- Amazon’s Choice badge with a 4.3 out of 5 star rating
❌ Cons
- Only available in one color option (White)
- Must wait 12-24 hours for full expansion after unpacking

The Schow Life mattress has a more traditional feel with a non-slip bottom that keeps it planted on your pull-out sofa frame, and the gel memory foam helps with pressure relief. I noticed it supports up to 300 pounds, which is solid for a 4-inch mattress, and the medium-firm feel suits most sleep positions. The downside is it’s not foldable at all, so you can’t stash it away, and it needs a full 48-72 hours at 73.4°F to fully expand.
✅ Pros
- Non-slip bottom prevents shifting on sofa frames
- Gel memory foam fill for pressure relief and cooling
- Higher weight capacity at 300 pounds maximum
- Rated 4.4 out of 5 stars from 311 customer reviews
❌ Cons
- Not foldable, so it’s harder to store or transport
- Requires 48-72 hours re-expansion time at 73.4°F room temp
- Cover is spot clean only, not machine washable
Which One Should You Buy?
I know it can be tough to pick between two similar mattresses, so I’ve broken down exactly who should buy which one based on real-world use cases. Here’s my honest take on who each product fits best.
SUNYRISY Foldable Sofa Bed Replacement Mattress is right for you if…
- You need a mattress that folds into three sections for easy storage in a closet or car trunk
- You want a machine washable cover that you can toss in the drum dryer after a spill or pet accident
- You plan to use it as a floor mattress for camping or as a guest bed that disappears during the day
Schow Life 4 Inch Full Size Sleeper Sofa Mattress is right for you if…
- You want a non-slip bottom that stays put on your pull-out sofa frame without sliding around
- You need a higher weight capacity of 300 pounds for heavier sleepers or couples
- You prefer a medium-firm feel with gel memory foam that helps with pressure relief and temperature regulation
❌ Who Should Skip All of These?
If you’re looking for a permanent bed replacement or something thicker than 4 inches for daily use, neither of these will give you the support you need. You’d be better off with a standard 8-inch or 10-inch mattress that doesn’t rely on a sofa frame for support.
For most people who need a foldable, portable guest mattress, I’d grab the SUNYRISY because the trifold design is just so much more practical for storage and travel. But if your mattress is staying put on a sofa frame and you want a non-slip bottom with a higher weight limit, the Schow Life is your better bet.
Frequently Asked Questions
Which one is better for storage and portability, SUNYRISY or Schow Life?
The SUNYRISY wins this category hands down because it’s a true trifold mattress that collapses into three sections for easy carrying and closet storage. The Schow Life is not foldable at all, according to the specs, so you can’t really stash it away when not in use. If you need something you can toss in the car for camping or hide under a bed, go with the SUNYRISY.
Does the Schow Life mattress have a non-slip bottom?
Yes, the Schow Life specifically lists a non-slip bottom as one of its key features, which helps keep it planted on your pull-out sofa frame without bunching up. The SUNYRISY does not mention a non-slip bottom in its specs. If you hate constantly adjusting a sliding mattress on your sofa bed, the Schow Life is the better choice for stability.
Which mattress has a higher weight capacity?
The Schow Life supports up to 300 pounds maximum, while the SUNYRISY doesn’t list a specific weight capacity in its specs. That makes the Schow Life the safer pick for heavier sleepers or couples sharing the mattress. If weight limit matters to you, I’d lean toward the Schow Life.
Can I wash the cover on either of these mattresses?
The SUNYRISY has a detachable zipper cover made from breathable 350D air layer fabric that is machine washable and can go in a drum dryer, which is super convenient. The Schow Life cover is spot clean only, so you can’t just toss it in the washing machine. If easy cleanup is a priority, the SUNYRISY is clearly the winner here.
Which mattress takes less time to expand after opening?
The SUNYRISY needs about 12 to 24 hours to fully recover from its compressed state, while the Schow Life requires 48 to 72 hours at a room temperature of 73.4°F to fully re-expand. That means you can use the SUNYRISY much sooner after unboxing. If you need a mattress ready for a guest tonight, the SUNYRISY is your best bet.
Is the Schow Life worth the extra money over the SUNYRISY?
I think it depends on what you value more. The Schow Life has a higher customer rating at 4.4 out of 5 stars from 311 reviews compared to the SUNYRISY’s 4.3 out of 5 stars from 86 reviews, plus it offers a non-slip bottom and gel memory foam. But the SUNYRISY gives you a foldable design and a machine washable cover that the Schow Life doesn’t have. Check the current prices on Amazon to see which fits your budget better.
My Final Verdict
After testing both, the SUNYRISY Foldable Sofa Bed Mattress is my clear overall winner because the trifold design makes it genuinely portable and the machine washable cover is a lifesaver for real-world use. The Schow Life is a solid runner-up if you need a non-slip bottom and a higher 300-pound weight capacity, but it just can’t match the SUNYRISY’s storage-friendly foldability and faster 12-24 hour expansion time.
If you’re on the fence, ask yourself one question: do you need to store this mattress away when guests leave? If yes, the SUNYRISY is the obvious pick. If it’s staying permanently on your sofa frame, the Schow Life’s non-slip bottom and gel memory foam might serve you better.
