Help Translating bed into Japanese

GoldCoinLover said:

In romaji, I thought bed in japanese is "beddo". If this is true, would it like this:
1) べっど
Or like this 2)べっド

This is confusing to me. Wouldn't it be number 2?

Actually, it would be #3) ベッド

English loanwords are generally written in katakana, and you generally don't mix hiragana and katakana within the same word. It's not really all that confusing.

I understand that ベ is "be", but then what is the small ッ is tu/tsu right? And I understand that ド is "do". But since japanese doesn't have any double consonants, for example double d (dd), what would I do?
