Ottoman/ storage Bed recommendation?

[Looseleaf]

I would love any advice if anyone has any.
I know I should probably try going to a showroom and lying on lots of beds but I think I will do that for the mattress and hoping the bed will be ok anyway as long as it has lots of storage! I'm guessing quality varies between brands and have also on an amazing Staples bed but can't find one easily so not sure what else to try

I like the look of and have sat on Brimnes from ikea. Planning on getting it for spare room once I have sorted it out. My neice has just started sleeping in Jnr if these (she's 28) and finds it get comfortable.

Thank you! I have ended up ordering a Visco 800 from British Bed Stored who let you return it for free if it isn't right. I can't wait to try it and see the clutter in our flat disappear!
