In the UK, a mattress on the floor is often called a 'futon'. It is rare for people to sleep like this in the UK as most people prefer a mattress with a bed base or frame so as to be higher off the ground.
EX "We had a holiday in Japan and got used to sleeping on a futon."
UKでは、フローリングにマットレスを敷くことを、futon（布団）とよく言います。このように寝るのは、UKでは珍しいケースです。大体の人は、マットレスをベッドベース、またはベッドの枠組みで使用するのを好み、床面から高くします。
例：We had a holiday in Japan and got used to sleeping on a futon.
日本で休日を過ごして、布団で寝るのに慣れました。
The most direct way would be to say that we were, "sleeping on the floor," with the addition of mentioning if we were on a mattress or a futon. In addition we can say that we were sleeping, "without a bed frame," which is the part that raises the bed off of the ground.
