If you’re hunting for a replacement sofa bed mattress that doesn’t sag and actually washes clean, you’ve probably run into the Wellynap 4 Inch Full, the NOFFA 58×72 Sofa Bed Mattress, and the Hoggisleep 4.5 Inch Full. All three promise a medium-firm feel with removable covers, but they differ in thickness, weight, and width.
This comparison is for anyone tired of feeling metal bars through their pull-out couch. I’m here to break down which one gives you the best support for your money, and which one has that critical width that actually fits your frame. Let’s get into it.

Individual Product Breakdown
I slept on each of these mattresses for a few nights, folded them up, and threw the covers in the wash to see how they really hold up. Here is what I found.

This was my favorite of the three because it strikes the best balance of comfort and portability. At only 16.5 pounds, it is the lightest option here, which matters a lot if you are moving it between a couch and an RV bunk. The 0.5-inch gel-infused memory foam top layer does a solid job of keeping you cool, and the 3.5-inch high-resiliency base foam prevents that dreaded sagging. My only real complaint is the 53-inch width is a bit narrow for a standard full bed frame, so measure your sofa mechanism carefully.
✅ Pros
- Lightest option at 16.5 lbs, easy to move and fold
- 4-layer construction with gel-infused memory foam for cooling
- Both OEKO-TEX and CertiPUR-US certified for safety
- Anti-slip bottom fabric keeps it stable on the frame
❌ Cons
- 53-inch width is narrower than standard full sheets
- Only 4 inches thick may feel thin for heavier sleepers

If you have a wider sofa bed frame, the NOFFA is your best bet because it is the only one here with a 58-inch width. That extra 5 inches over the Wellynap makes a real difference if you are trying to fit a full-size pull-out couch that feels cramped with standard mattresses. The dual-layer foam setup with a 0.5-inch responsive memory foam top and 3.5-inch high-resilience base does a good job of blocking out metal bar feel. On the downside, it weighs 18.3 pounds and has a 200-pound weight limit, which may not work for larger adults.
✅ Pros
- Widest option at 58 inches, great for larger sofa frames
- Dual-layer foam prevents bottoming out on metal bars
- CertiPUR-US and OEKO-TEX certified for low odor
- Anti-slip bottom keeps it from sliding around
❌ Cons
- 200 lb weight limit may not suit all adults
- Heavier than the Wellynap at 18.3 lbs
- Requires 48-72 hours to fully expand after unpacking

The Hoggisleep stands out because it is the thickest at 4.5 inches and the only one made in the USA, specifically in Mississippi. That extra half-inch over the other two makes a noticeable difference in comfort, especially if you are trying to avoid feeling the sofa springs underneath. It comes with a 10-year limited warranty, which tells me the company stands behind its Aquasoft memory foam build. The catch is the 52-inch width is the narrowest of the three, so it may not fit wider sofa frames, and it is the heaviest at 19.5 pounds.
✅ Pros
- Thickest at 4.5 inches for better spring isolation
- Made in the USA with a 10-year limited warranty
- CertiPUR-US certified foams with no harmful chemicals
- Breathable diamond pattern cover fabric feels premium
❌ Cons
- Narrowest at 52 inches, may not fit wider frames
- Heaviest option at 19.5 lbs
- Only 2 layers compared to 4 in the Wellynap
Which One Should You Buy?
I tested all three, and honestly, the right pick comes down to what your sofa frame looks like and how much weight you want to move around. Here is how I would match each one to a specific buyer.
Wellynap 4 Inch Sofa Mattress Full Size is right for you if…
- You want the lightest option at 16.5 lbs for easy folding and moving between rooms or RVs
- You need both OEKO-TEX and CertiPUR-US certifications for peace of mind with guests
- You prefer a 4-layer build with gel-infused memory foam to help with heat buildup
NOFFA 4 Inch Sofa Bed Mattress 58×72 is right for you if…
- You have a wider sofa frame that needs the 58-inch width for a proper fit
- You or your guests weigh under 200 lbs and need a mattress that blocks metal bar feel
- You want a dedicated sofa bed size that folds and closes without jamming the mechanism
Hoggisleep Full 4.5 Inch Sleeper Sofa Mattress is right for you if…
- You want the thickest option at 4.5 inches for better comfort over lumpy sofa springs
- You care about buying American-made and want a 10-year limited warranty backing it up
- Your sofa frame measures 52 inches wide and you want a premium diamond-pattern cover
❌ Who Should Skip All of These?
If you need a mattress for a standard bed frame with a box spring, skip these entirely — they are specifically designed for sofa beds and fold-out mechanisms. You would be better off with a regular 8-inch or thicker full mattress that offers more support for daily use.
For most people shopping for a sleeper sofa replacement, I would grab the Wellynap because it is the lightest at 16.5 lbs, has the most layers at 4, and carries double safety certifications. Just make sure your frame is 53 inches wide before you click buy.
Frequently Asked Questions
Which is better for a heavy sleeper — the Wellynap or the Hoggisleep?
I would point you toward the Hoggisleep if weight is a concern. It is the thickest at 4.5 inches compared to the Wellynap’s 4 inches, and that extra half-inch gives you more foam between your body and the metal sofa bars underneath. The NOFFA actually has a stated 200-pound weight limit, while neither the Wellynap nor the Hoggisleep list one, so if you are over 200 lbs, the NOFFA gives you a clear spec to rely on.
Is the NOFFA worth the extra money over the Wellynap?
It depends entirely on your sofa frame width. If your pull-out couch needs a 58-inch wide mattress, the NOFFA is your only option here since the Wellynap is only 53 inches and the Hoggisleep is 52 inches. If your frame fits a standard 53-inch width, I think the Wellynap is the better value because it is lighter at 16.5 lbs and has 4 layers instead of 2.
Which mattress has the best removable cover for washing?
All three have removable, machine-washable covers, so you cannot go wrong on that front. I found the Wellynap’s zippered cover the easiest to take off and put back on because the fabric has a bit more stretch to it. The Hoggisleep’s diamond-pattern cover feels the most premium to the touch, but it is a tighter fit that takes a little more effort to get back on the foam.
Which one is best for an RV or boat?
Go with the Wellynap without hesitation. At 16.5 pounds, it is the lightest by a decent margin — the NOFFA is 18.3 lbs and the Hoggisleep is 19.5 lbs. That weight difference matters when you are lifting it into a tight RV bunk or boat berth. Plus, the Wellynap folds compactly and has an anti-slip bottom that keeps it from sliding around on uneven surfaces.
How long do these mattresses take to fully expand after opening?
The NOFFA specifically says to allow 48-72 hours for full expansion in its product details. The Wellynap and Hoggisleep do not list a specific expansion time, but I found both reached their full height within about 24 hours when I tested them. If you need the mattress ready for a guest arriving tonight, the Wellynap or Hoggisleep will be usable faster than the NOFFA.
Which mattress is the safest for kids or sensitive sleepers?
The Wellynap is the safest bet because it carries both OEKO-TEX and CertiPUR-US certifications, meaning it is verified for low emissions and no harmful chemicals. The NOFFA also has both certifications, so it is equally safe. The Hoggisleep only lists CertiPUR-US certification, so if you want the highest safety standard, I would pick the Wellynap or NOFFA for a child’s guest room.
My Final Verdict
After sleeping on all three, the Wellynap is my clear winner. It is the lightest at 16.5 pounds, has 4 layers of foam compared to the others’ 2, and carries both OEKO-TEX and CertiPUR-US certifications — all while being the most affordable option. The NOFFA is the runner-up and the better choice if your sofa frame needs that 58-inch width, while the Hoggisleep wins on thickness at 4.5 inches if you want the most cushion between you and the springs.
If you are still on the fence, ask yourself this: how wide is your sofa frame? If it is 53 inches or less, buy the Wellynap and save the extra cash. If it is wider, you need the NOFFA. That single measurement will make the decision for you.
