Looking for quality garden furniture

We bought a house in the Manchester suburbs last year, proper dream place we'd been wanting for ages. Got our own little garden with a lawn, lounge area, and a spot for the barbecue. There's a decent-sized terrace as well where you can sit outside and stay dry when the rain starts, which happens often enough round here. Previous owners even left their garden furniture behind, which seemed brilliant at first. Thing is, it's absolutely rubbish quality, to be honest. Just over six months and it's already falling apart, looks terrible, and I'm genuinely nervous sitting on that outdoor sofa now in case it collapses. Need to get something better sorted for the garden. Where's good to look for furniture in the UK? And what material should I even go for so it'll actually last more than one season?
