carpet indentatons

[sneezecake]

how do I get rid of them?
getting new sofa and the marks from the old sofa will show, any ideas?
TIA

Pop an ice cube on it and leave it to melt and then give it a scrub - it works honest!

I've heard that an ice cube works too - not tried it myself though.

oh, I tried an ice cube but put it in a bag so it wouldn't melt everywhere, I didn't realise it was suppose to lol, will try it again!
