Top fixing is a dream...
Delighted with this loo seat. Fitting was easy, features are outstanding, completely non-slip. We have a 'modern' style bathroom suite which, to be honest, would be better off in a skip. The design is just perfect for not being able to get your arm around, under, over, through, whatever, to fasten anything. What should be the easiest of DIY jobs becomes a bone crunching nightmare. Last time we had a new seat (about 5 years ago) it took two of us just to hold the bolts and washers on so we could tighten it up, it really is almost impossible to reach the underneath of the bolts. Then we discovered these 'top fixing' loo seats and bolts. I was a bit sceptical but ordered one to take a chance. It's fantastic!! Extremely easy to fit, didn't need the instructions at all. The top fixing rubber bungs fit our pan superbly, nice and tight straight away, rock solid after the bolts were tightened. A great feature is the removable seat section so if the bolts become loose they can be tightened up in 60 seconds. The placement 'lugs' on the bottom of the seat (the bits that land on the pan rim) are made of a solid material that's completely non-slip on our pan. Even if the bolts came out completely I can't see this moving very far. Even with the bolts tight, there is some slight movement of the whole seat assembly, but this isn't because it's becoming loose, it's just the play where the removeable seat fixes into the mounting bolts. We love the soft close as well. Sooooo many times I've woken up in the night to pee, crept around the room, quietly gone into the loo then dropped the old seat with one hell of a crash. Not possible anymore. Bliss. I made just one change to the manufacturers intentions for fitting. There are two lengths of bolts provided, short for top fixing and long for bottom fixing. I used the long bolts but still used the top fixing method. I did this so that we could practice our contortion and bone breaking yoga skills to try to get the bottom bolts on as well if necessary. I genuinely don't think we'll need to do this.

Very good seat!
Quite a sturdy seat, this is easily kept clean and fits great! I’m not a small person at almost 13 and half stone and suits fine..I think instructions could be clearer as I didn’t realise the rubber had to go through hole too but after sussing it out myself it doesn’t move at all!! Good value too, soft close a dream! Update: had this seat nearly 3 months now and it hasn’t worked loose once! Annoying when I read other reviews stating theirs comes loose..they are obviously fitting it wrong! One reviewer was pushing rubber bung through hole with the screw attached!! Another says it takes 2 people, one to screw and another to hold the rubber underneath? I mean really what were they doing!! Do this : 1) remove screw from rubber bung an press bung through hole in toilet..I had to really squeeze it through, it leaves a lip round hole.. 2) put spiked round hinge base over hole on top of rubber lip 3) put washer on screw an place in slot on base and screw into hole.. the rubber tightens this up.. add seat to align an tighten screw fully.. job done.. add cap to cover.. it won’t go anywhere!! I’m 68 and a disabled woman so if I can do it anyone can..plz don’t knock the product because u are doin it wrong!

Good quality soft-close toilet seat at a budget price
I recently purchased this soft-close toilet seat and overall I’m quite satisfied with the value for money. Installation was straightforward and didn’t take much time. The soft-close mechanism works smoothly and prevents the lid from slamming, which is especially useful at night and helps reduce noise. The material feels decent for the price, and it fits well on a standard toilet. It also looks clean and modern, which is a nice upgrade from a basic seat. You can adjust by yourself. Easy to replacement. Pros: Soft-close feature works well and closes quietly Affordable price compared to similar products Easy to install without professional help Lightweight and fits standard toilets Easy to clean surface Cons: Nothing to say make you sure the shape is matching one. A great budget-friendly option if you want a soft-close feature without spending too much. It does the job well and is perfect for everyday use.

Lovely loo seat, instructions a bit opaque...
This is a really good quality solid soft-close loo seat, comfy and easy to clean, and we're very happy with it. Hence five stars. The instructions were a bit of a puzzle to me; maybe if you are more diy-tastic you would have been fine. The translations are interesting (mute toilet seat). The exploded diagram of the fixings appears to show the rubber grommet plug being fitted on top of the porcelain and screwed down. I tried that. It was incredibly difficult to get the bolt to seat into the socket in the grommet. The seat wobbled like crazy. Cue fretting and thoughts of doing a return. But then I realised that if I inserted the grommet (or "cork" as it is termed in the instructions) from the underside, so that it actually fitted through the hole in the porcelain, it would be fine. After a bit of fiddling with some radio pliers so that I could grab the top collar of the grommet, I persuaded it through. There were some bad words because one side of our loo is really much too close to the wall, hence access problems. I got there and hooray it all fitted together just fine. It's strong and stable now unlike the government. So I am very happy. I hope my adventures might help someone else who like me is a bit DIY 101.

Not great
Reasonable quality. I imagine it would be hard-wearing but I found it very difficult to fit. I had expected a spacer to be included but was sadly mistaken. Seat was in use about 6 weeks but had to tighten it regularly - as I said i found it difficult to fit. Threw it out and replaced it with one half the price.

Oval Signature...worth the extra
Great toilet seat had 3 of these. Don't go for the bliss model, go for the signature model. The extra cost is worth it. Top or bottom fixing , if you go for bottom fixing as per instructions,you need to remove the rubber bung & screw, you don't need them. Just replace them with longer screw & washer & put white bung in toilet pan holes , then insert & tighten with white plastic nut & white washer underneath. Go for it, but remember to measure you loo pan seat area before you buy!

Finally a sturdy toilet seat!
My mum recently had her toilet replaced due to her stupid son dropping a hammer on it and smashing the porcelain. the replacement looked like a standard toilet bowl to be fair but she went through 3 different seats and kept getting the same issue. after a few days they would start to wobble and become loose. going to the bathroom at my mums was like a ride on the log flume. after spending around £80 total on failed seats i told her to 'leave it with me', and i would sort it. after some assurance that I wouldnt go near it with a hammer she finally agreed. I then did more research into toilet seats than any one person should do, and finally purchased this one with doubting confidence. Bit of background on me - i have installed up to 9 toilets seats in my life, so i am a bit of an expert. That being said i had never seen fittings like these. you push the black rubber seals into the holes on the toilet bowl then screw into them and the seals contract and snuggly and tightly fill the holes. i was quite impressed with how simple it was to install. my mum was blown away with the fact that in just one button press you can remove the seat for easy cleaning, and the slow closing is a bonus too. needless to say, 6 months down the line and the seat is still firmly in place. you wouldn't think technology of a toilet seat could advance much, but if someone dropped a hammer on mine tomorrow i would purchase one of these.

Facilité d'installation
Pour changer le mien qui s'est cassé et là je dois dire que je suis ravi par la facilité d'installation, je tiens à préciser que je suis handicapé moteur et n'ai qu'une main de valide et là avec ma seule main ça m'a pris 15 minutes à peine pour l'installer j'ai choisi l'option installation par le haut puisqu'il est possible de l'installer soit par le haut ou le bas, en ce qui me concerne par le haut bien plus pratique nul besoin de se contorsionner, reste à voir maintenant la solidité dans le temps mais jusque là parfait je suis ravi.
