Device to stop door slamming?

[Blessyou]

Hi, can anyone recommend a device to prevent DS from slamming internal doors?

I need to be able to close them so those foam jobbies are no good.

Fire closer type things like you get in shops and offices?

Ikea do these www.ikea.com/gb/en/catalog/products/10098949/

which you install on the floor.

Thanks.

I need something like the one in poltergoose's link.

I need to keep the doors closed due to draughts, but they are partly glazed and am worried he'll smash one one day.

We have the door slam ones too. Have a look through this link for other ideas: www.safetots.co.uk/Safety-Essentials/Door-Safety-Products/Slam-Stoppers/c1_11_897/index.html
