Seni Super Plus Adult Diaper Review

 *For more information on how I do reviews see Diaper Test Methodology

Summary

The Seni Super Plus is a full featured but lower absorbency version of the Seni Super Quatro. Like its sibling, this diaper has a cloth-like backsheet and is rated with overnight absorbency. But it’s also highly durable and would be a great choice for daily wear as well. I rate it very high for comfort. It has a European fitting so perhaps a little on the small side. In terms of absorbency I feel it will consistently take about 1~2 wettings before leakage would be a concern in daily or overnight wear. I would highly recommend this diaper to those who like the Seni Super Quatro but can’t justify its price tag. The Seni Super Plus can often be found at a far more affordable unit cost.

Key Features:

• Breathable backsheet
• Standing inner leak barriers
  
• Dual waistbands
• Repositionable tapes

Pros:

• Snug/comfortable fit
• Very breathable
• High absorbency/leak protection
• Good price/quality ratio

Cons:

• Limited availability
• Rear padding surface dampness

Surface Dampness Rating: 8

The Seni Super Plus performed quite well when it came to surface dampness. It wasn’t quite up to the level of the Seni Quatro, but this diaper is not nearly as absorbent as that one. I was a bit concerned with the bits of surface dampness that showed up relatively early in testing. However, there wasn’t any considerable surface dampness until the 3rd wetting. In real world testing, it was better than I expected. I mostly noticed surface dampness near the rear of the diaper, but a bit less than the Tena Stretch Brief Super and it was comparable to the Lille SupremFit Maxi in this regard.

Standing-Sitting Rating: 8
The Seni Super Plus had no problem absorbing the first wetting while standing and showed no signs of leaking upon sitting shortly afterwards. The diaper remained comfortable and breathable at this point with little surface dampness. The second wetting was absorbed quickly as well, the front of the diaper felt quite damp, but the rear padding remained dry. There was no sign of leakage on the second wetting while seated and the diaper continued to feel comfortable. The third wetting quickly consumed the front padding and there was a fair amount of pooling at the mid-section. This dissipated over a couple minutes but there was noticeable surface dampness at the rear afterwards. Surprisingly, there was little if any sign of leakage afterwards, the leak guards held up impressively. There was again considerable pooling on the fourth wetting and at this point there was considerable leakage. The surface dampness was also a bit more noticeable, but this diaper is very breathable and I didn’t find the dampness had a major effect on comfort. By the end of the test, much of the padding was used aside from a small amount at the very back, suggesting good wicking. It seems this diaper should easily manage 1~3 wettings for daily wear and is quite resistant to pressout.

Total Wettings: 3
Used to Total Padding Ratio: 74%
Padding to Absorbency Score: 0.77 ml / cm² (0.17 oz / in²)

Lying Down Rating: 8

The Seni Super Plus easily absorbed the first wetting when lying down with no signs of leakage. The surface dampness was only short lived and after that was barely noticeable with the rear padding remaining mostly dry. The second wetting was again easily absorbed, but with a little more noticeable surface dampness toward the rear. Even so, it remained comfortable and surface dampness decreased after a few mins with no sign of leakage. On the third wetting there was initially substantial pooling but it subsided after a few minutes, I feel the diaper would likely have more leaked if sitting afterward but while lying down there was only a relatively minor leak through the rear leg gathers. Moreover, much of the front padding was still untouched, suggesting more room for absorption. I was impressed by how well the leak guards and leg gathers held up, but then it is a less absorbent version of the top performing Seni Super Quatro. I’m confident this diaper can consistently handle 1~3 wettings while lying down

Daily Wear and Bedwetting

The Seni Super Plus is a great mid-range diaper that works well for both daily wear and bedwetting. In terms of absorbency, I found it comparable to the Nexgen Absorbent Plus, but significantly less than the Seni Super Quatro. In terms of design, it’s almost identical to that of the Seni Super Quatro and has exceptional fitting and comfort. I found this diaper to be quite durable when wearing out during the day, this was true regardless of whether it was wet or dry. The tapes are easy to apply and remove with seemingly little effort, but they hold surprisingly well and I never had issues with these diapers coming loose or sagging. I did find they result in a bit of a diaper bulge, particularly at the rear but not as much as some others like the Abena M4. In daily wear I found they could consistently manage two wettings before significant leakage would be a concern when seated. Once in a while a little after sitting down I did notice some very minor leaks. That only ever happened on the second wetting, so I feel it’s quite reliable to that point but more likely to leak on the 3rd wetting. When testing for bedwetting I never experienced any leaks, I believe you’d need to be a very heavy multiple wetter or sleep in a funny position for that to be a concern. It will easily absorb a single wetting but shouldn’t be pushed past 2 as I found the rear padding saturates relatively quickly. I also noticed the surface dampness more when lying down as the rear padding is a little more prone to it. The leak guards and leg gathers are snug and quite moisture repellent, particularly for a cloth-backed diaper. All in all, I don’t have any complaints, this diaper isn’t quite at the premium level but it has a consistent high quality performance that is well above many comparable mid-range products like the Tena PROskin Stretch Night. It’s “breathability” is also likely to be a huge plus for wear in warmer weather.

Suitability for Bowel Incontinence: 7

The Seni Super Plus comes a bit below the Seni Super Quatro when it comes to suitability for bowel incontinence. Overall it should still be fine for this purpose and has critical beneficial features like extensive rear padding, standing inner leak guards and front/rear waistbands. However, I found it was a little more susceptible to odors than the Seni Super Quatro, likely due to the lower level of absorption.

Wear & Tear Tests

Fitting

The Seni Super Plus has a cloth-like backsheet with hook & loop type fasteners. The fasteners also include a little adhesive tape material, not unlike the Seni Super Quatro. The fasteners can be repositioned anywhere on the backsheet multiple times. They lose a little stickiness over adjustments but these tapes are high quality and have a strong grip that won’t easily slide.

3.1 Seni Super Plus Fastener

 

Ease-of-Use Rating: 10

The Seni Super Plus is a very user-friendly diaper. Throughout my testing I never had an issue attaining and maintaining a snug comfortable fit. The tapes are high quality and hold very well on the backsheet once placed. Unlike many cloth-backed diapers, this diaper will not come loose or sag. The dual waistbands are a huge plus, allowing this diaper to wrap the wearer’s body. Likewise, it’s very easy to remove when it’s time for a change. I feel this diaper is suited equally well to both care home settings and personal usage. Moreover, the wetness indicator is not overly sensitive to moisture, but will change from yellow to blue when wet. The only thing that can be a bit inconvenient is that the standing inner leak guards can initially be stuck to the leg gathers so you’ll want to push them apart when applying a new diaper. However, I consider that pretty minor and really I don’t think one could ask much more of it.

3.2 Seni Super Plus Diaper Fit

 

Comfort

Comfort Rating (dry): 10

The dry comfort of the Seni Super Plus is right up there with the Seni Super Quatro. This diaper has one of the best fits on the market and snugly conforms to the wearer's body. The dual waistbands play a big role in this, but it’s also a result of its construct that avoids padding bunching while the tapes and wings wrap over the hips in a way that prevents loosening/sagging. This diaper is also highly breathable and throughout my testing I never had so much as a hint of clamminess. The padding is also very soft, as are the backsheet and leg gathers. During this review I wore this diaper overnight and actively during the day but never had any sense of chafing or skin irritation. I would say the padding softness is slightly less than that of the Attends Premier Overnight, but not enough to detract from its comfort. No complaints when it comes to dry comfort, the Seni Super Plus earns a perfect score.

Comfort Rating (wet): 9

The Seni Super Plus scores highly when it comes to comfort when wet. It’s not quite as good as the Seni Super Quatro when it comes to surface dampness, but remains comfortable with relatively little dampness in up to two wettings. When surface dampness does occur it tends to be most apparent in the rear padding, similar to the Nexgen Absorbent Plus or Egosan Ultra. Otherwise, this diaper has a construct very similar to the Seni Super Quatro, the tapes and waistbands do a great job at retaining a snug fitting and resisting sagging. The padding is very resilient to clumping or tearing. Moreover, it provides a great balance of protection against surface dampness and the leak guards are incredible for a cloth-backed diaper. In this way it differs from the Nexgen Absorbent Plus, which, while highly breathable, tends to accumulate surface dampness near the leg gathers. In the Seni Super Plus I noticed very little surface dampness near the leaks guards or leg gathers once absorbed. It’s highly breathable and doesn’t lead to any clamminess, even wet, I expect it to hold out well for active wear or overnight wear.

3.3 Seni Super Plus Topsheet and Backsheet

Durability

Dry Padding Deterioration Proportion: 5.1% (topsheet), 6.4% (backsheet)
Shake Deterioration Test: 8 shakes to deterioration

Durability Rating (dry): 9
The Seni Super Plus held up nearly as well as the Seni Super Quatro when it came to dry durability. There was very little padding deterioration and the tapes consistently held on until it was time for a change. Likewise for the backsheet, where there was no sign of stretching or damage. I wouldn’t have concerns wearing this diaper while out even during more active days. This diaper’s padding is highly resistant to clumping or tearing, it doesn’t sag, and the wetness indicator isn’t affected by sweat or light dribbles. Most deterioration during the dry durability test was due to padding collapsing inward between the legs. You couldn’t ask for much more when it comes to dry durability.

Durability Rating (wet): 9

The Seni Super Plus scores well for durability when wet, much like its higher absorbency equivalent. It proved to be one of the most resilient diapers tested during the wet shake test, managing around 8 shakes after the lab capacity test before the padding started to collapse. This performance was backed up in daily wear, when in spite of a long day of active wear and several wettings the padding showed few signs of clumping or tearing. It really doesn’t feel much different in its wet state compared to its dry state. Another plus was in the high quality of its tapes, I found it to be highly resistant to sagging under weight. I couldn’t really find any issues in this diaper when it comes to wet durability but there was slightly more deterioration than the Seni Super Quatro.

Discretion Tests

Profile

Front Rise Above Waistline (Jeans, Sweatpants): 5 cm (2"), 4 cm (1.6")
Back Rise Above Waistline (Jeans, Sweatpants): 7 cm (2.8"), 2.5 cm (1")
Side Rise Above Waistline (Jeans, Sweatpants): 5 cm (2"), 3 cm (1.2")

Profile Discretion Rating: 7

The Seni Super Plus has a very similar profile to that of the Seni Super Quatro, in spite of the difference in padding thickness. It has a pretty snug fit and isn’t prone to sagging but it does present a bit of a diaper bulge at its rear. I rank this diaper about the same as the Quatro in terms of profile discretion, maybe not the best for tight clothing but still would require some care to cover with looser clothing.

Noise

Noise Rating: 10

The Seni Super Plus has a very similar design to the Seni Super Quatro and is unsurprisingly very quiet. Throughout testing I never noticed any noise from this diaper. Even the tapes are remarkably quiet. I can’t find any flaws in terms of noise discretion and thus a perfect score.

4.3 Seni Super Plus Noise Profile

Odor Reduction

Odor Reduction Rating: 8
Overall the Seni Super Plus was very odor resistant. It has a cloth-like backsheet which can be a problem for containing odors, but it also has a snug fit with good leak guards and a dual waistband. The padding is also quite resistant to odors. That said, it wasn’t quite as good as the Seni Super Quatro in this regard, perhaps due to the less absorbent padding and a little more tendency for surface dampness.
