Decent 90X200 mattress?

[Deerfoot]

We bought a great bed in Germany while we were living there a few years ago.

It has two separate bases and as a result needs a separate 90X200 mattress for each base.

Can anybody recommend a decent mattress that's available in this size? They don't appear to be that common in the UK.

Thanks in advance.

I could pop down to the Southampton Ikea I guess, I'm sure they do that size, just not sure they're decent...
