A surprisingly useful design even if you do not have kids

SCNovember 13, 2025

I bought this mainly for the upgraded slow close feature and the “never loosen” design, but the built-in child seat turned out to be more useful than I expected. I do not have a child at home, yet the extra seat has been a welcome feature when friends or family with little ones come over. It flips down easily and feels sturdy, and the magnetic hold keeps it out of the way the rest of the time without affecting regular use. Installation was very simple. The option to mount it from the top helped a lot, especially since I usually dread dealing with toilet hardware. Once it was in place, the seat stayed secure and did not wiggle at all. The slow close function works well, and the lid settling quietly has been one of those small quality improvements that makes daily life a little nicer. Cleaning is also much easier now. The quick release design lets me pop the whole seat off and clean around areas that are usually difficult to reach. It makes the bathroom feel fresher with less effort. Even without a child in the house, the design adds convenience, comfort, and a sense of readiness for when young visitors show up. It feels durable, fits the toilet well, and the added features make it a worthwhile upgrade. Read more

Elongated Slow Close Toilet Seat with Toddler Seat Built In, Potty Training Seat, Easy to Install and Remove, Never Loosen, White This toilet seat fit our Kohler elongated toilet very well and the installation was quick and simple. The built in toddler seat is a feature I really appreciate because it makes potty training easier and can be removed once we no longer need it. The seat itself is easy to detach which makes cleaning much more manageable. The slow closing lid is another nice touch since it prevents any loud slamming noises and keeps everything calm and quiet. Overall it is a practical and well designed seat that works well for both adults and toddlers. Read more

Genius Design That Makes Potty Training So Much Easier!

DMOctober 22, 2025

This MermoGuiny round slow-close toilet seat with a built-in toddler seat has been a total game-changer in our household. The integrated potty training seat is incredibly convenient — no more juggling separate toddler seats or dealing with wobbly attachments. Our child can easily flip it down independently, which makes potty time feel empowering and helps build confidence. When not in use, the magnetic design keeps the smaller seat neatly out of the way for adults — such a clever touch! Installation was simple and took just a few minutes, with everything fitting securely and evenly. The “never loosen” feature really holds up to its name — the seat stays firmly in place even after weeks of use. The slow-close function is another plus; no more loud slamming lids, which is great for nighttime bathroom trips. The polypropylene material feels durable, smooth, and easy to clean — definitely higher quality than expected at this price point. I also appreciate that the toddler insert can be detached later, so the seat grows with the family. Overall, it’s a well-made, practical, and thoughtfully designed product that combines functionality for both adults and kids. If you’re potty training or preparing to, this is a must-have upgrade for your bathroom! Read more

A must have for households with small children!

TMI T-rexNovember 3, 2025

I really wish I had tried a seat like this sooner. So far, I have wasted so much money on potty chairs only to find they pinch, are not sturdy, or they are not easy for my son to use. The MermoGuiny toilet seat has none of these issues! It is sturdy and easy for both my husband and my son to use. The smaller seat can be easily brought down by my son and stays up when my husband needs to poop. In addition, the installation was super easy. So easy that my 3-year-old was able to help! This made him actually want to use the potty which has made my job as resident nag much easier. Read more

Perfect size, easy to use and the preschooler can do it 'all himself'

CustomerNovember 9, 2025

Elongated Slow Close Toilet Seat with Toddler Seat Yay! It fit our elongated toilet perfectly. The seat comes with everything you need to install and it's very quick. The little toddler seat is built in, attached, but when you flip it up for adults it's completely out of the way and stays back (it doesn't fall forward to hit you on the back or the backside). The little one can use his step stool to reach the toilet and simply raise the lid to find his little seat ready for him, or he can flip it down if it's already up. Perfect size for a 2-3 year old and I don't have to deal with the two 'go to' options we have been using! Great price point and easy to wipe down and clean. Read more
