Single bed and duvet for 16 year old (Surbiton KT6)

I'd love to organise a bed for my 16 year old profoundly autistic son.
He will be in a box room and it would be great to show him where he will sleep before we land in the UK. Moving January 2026.
Will need help arranging transport.
Looking for:
Single bed
Teenage looking duvet cover
Duvet inner
A few musical stim toys
