Can you get midi sleepers that take a cotbed size mattress?

Or are they all just standard single?
We've got very good new mattresses for both boys and dont want to stop using them, but ds1 could do with a midi sleeper to store all the -crap- toys under, rather than his toddlr bed, which fits nothing under it!

Try www.boxroombeds.com mentioned in an earlier post that I can't find! They do a midi sleeper and a loft bed that take a cotbed size mattress.

I have just bought a mid sleeper from Tesco Direct-Huge mistake do not do it-learn from my mistake.

However,I was in a simailar position and because DD is only 2.5 I have put cotbed mattress on and used the spare space at the bottom to fill with soft toys.
Duvet seems to fill any space at the sides.
