Harry, thanks for that. I've just been looking again and I can't see
any way of tightening the fit. It does seem a little strange though
that the play is only at one end - but the fact that the fixings are
different from those at the other end certainly suggests that it's a
deliberate design feature.

It is quite likely that the original sofa was purchased from some paki shop
on some ****ty industrial estate and sold on to you. Sold on because it was
not fit for purpose. My late wife bought from these arseholes against my
wishes, I was working at the time. The arseholes would not even take the
cardboard away. The furniture fell apart within 18 months, it cost over £1k.
A telephone call always got the same response ...... "De boss is not here".
I am not racist, I just hate the paki ****s.
