Where can I buy a sleep wedge for a baby with reflux, in the UK and online?

[NbgsYellowFeathers]

I've seen them on a few US sites but I'd rather buy from the UK. However I can't seem to find anyone that sells them.
The only ones I have seen are very low. I'm looking for quite a high wedge.

what about this?

you could always raise the cot legs a bit as well if it's not high enough but I would have thought that for safety there's only so high they can go?

Yes thats quite a good one but I was thinking a bit higher. I have seen them higher. They look similar to a rocker but without the seat part IYKWIM.

I have already raised the end of the cot but it hasnt really helped. Ds still struggles and wriggles about.

Don't Blooming Marvellous sell them....not 100% sure though

don't know if this is higher - it says 15 degrees which doesn't seem like much
jo jo maman bebe have one

don't seem to be able to find any higher ones though

Thank you very much.
I wonder why they didnt come up on google
