Mine was transverse/breech/oblique for a bout 2 months, untill I had my 36 week check. Midwife sent me for a scan, and told me they would keep me in, incase waters broke = complications.
I spent the weekend on all fours, wiggling my bum about.
When i went for the scan, i'd turned it to breech (bum down).
They said to come back i 2 days, to have baby turned.
I really didn't want this, so spent the 2 days just on my hands and knees, crawling aound the house.
I had my bum in the air, and made sure my head end was lower. Whilst doing a sort of hoola hoping motion! 
Bloody tough on my knees, cause we dont have carpet. And my arms ached like mad.
I didn't sit for long, or slouch on the couch.
It worked though, as when I went to get baby turned, it was head down!!
Fingers crossed it has stayed that way. As I had no idea it had turned, and still have no clue which way it is, as it throws some strange shapes in there 
Give it a go, might be worth the discomfort
