I love lounging in bed.

べっどでおろしょくくつろぐことがすっきですは。

*It's better to write ベッド with katakana because it came from English.

"Lounging" has several translations and I choose くつろぐ this time. 

I would say だいすき for "love" and すき for "like", however, it depends on the person and the situation. 

Good luck!
