Where can I find a really large footstool?

[Pannacotta]

I'd like something large and squashy, which is at least 1m square, a bit like this
loaf.com/products/wet-dog-footstool

but I don't have £500 to spare.

Any ideas where to look?
TIA

Well, it's not as bit as you've asked for, but at this price, maybe you could get two: www.made.com/hawkins-storage-footstool-grebe-grey?c=GOOGUKSHP&_$ja=cgid:10422604006%7Ctsid:54955%7Ccid:313520206%7Clid:59863962646%7Cnw:g%7Ccrid:48227879926%7Crnd:15910202195990667469%7Cdvc:t%7Cadp:1o3&mkwid=xjO9Yg5U&pcrid=48227879926&gclid=CPuc3I_Bkr4CFbShtAodDUkAPA

I really like that Sand thank you, I think two of those could work.
