Soft close toilet seat - recommendations for one that stays up!

Hi everyone

Can anyone recommend a white plastic one of these that is (more) adjustable front to back?

My cistern is a) not quite square to the pan (the product of living in an old house with no true walls) and b) has a slight overhang on the cistern top cover. As a result, the new seat I've been trying to fit won't stay up for man pee situations. The old non soft close one was fine.
The new one looks pretty vertical, but obv it needs to be able to lean back a little more to hold it up.

I guess I can try a few different brands to see, but just wondered if anyone had experience here and could advise me?

many thanks

Have a look a Bemis.

Thanks for that. I checked out the website, but the plastic soft close ones are not adjustable at all. The moulded wood ones are, but not sure I fancy these....

Did you recommend then as they don't need adjusting?

Have a look via B&Q. These seats are adjustable, can't think of any that can't be.

Thanks - the soft close versions all seem to be moulded wood, I'd rather have plastic.
Also when I looked at the fitting video, there was defo no adjustment on the plastic ones.

However, some of the reviews do say that they 'stayed up when others didn't' so maybe I'll give one a go - I can always return it I guess

thanks
