thread Room 18 in the HIE in Dedham
has a very bouncy mattress.
Suspect it's not to standard spec!
permalink It will be the old spec
was technically possible until 3 years ago but a lot of people stopped using it before that.

the new beds with the toppers are really good actually
permalink This wasn't one of them.
I'd be surprised if this was standard spec tbh, it was absurdly bouncy.
permalink Sounds like the respa mattress, they were a bit iffy
Managed to scrape past the spec when tested but sometimes some other crap turned up on site

But the spec was a bit stupid
