My favourite piece of technology

My favourite gadget was bought by my grandfather when I was like ten years old, I've been using it since then in many different ways, but now it is half of what it was back then because I used to share it with my one of my sisters but now both of us have our own part of it.

It has two main parts but people don't use it without accessories that make its use more comfortable. It is commonly used everyday but architecture students don't use it longer than 4 hours a day.

I like it because it is the most comfortable piece of technology in my house and I like to use it whenever I get home.

I think my life would awful without it. because I really love this gadget and I wouldn't have how to rest everyday.
