Hello, my name is Ko and I’m currently thinking of
purchasing 20ft dome. But before I make a decision,
I need to be clarifyed with some of the question that
I have right now.

Is this dome could be set up without the ladder or any
sort? The dome seems to be really tall.

Yes; See https://shelter-systems.com/upin30min.html

Is this dome have warranty or guarranty of anysort,
if it colapsed and breaked because of weather or accident?

SNOW AND EXTREME WIND CAUTION

Your dome is a lightweight, portable structure and should not be relied on as your sole shelter in extreme weather. Your dome could be destroyed in extreme weather and your life or safety could be at risk.

In heavy snow your dome could collapse which could damage what you have in it or compromise your shelter. Do not rely on your dome as your only shelter where it snows.

Your dome will blow away if it is not anchored properly. Study the anchoring instructions carefully and apply all appropriate means to secure your dome to the earth. Rain will soften the ground and greatly reduce the holding power of the stakes. We provide good general purpose stakes, but they cannot cover all ground conditions. Wind will at times come up unexpectedly. Be prepared!
Remember that the dome is a lightweight, portable structure. Its strength comes from tension, not mass or rigid components. Exposed sites with unusually extreme winds are not recommended. It is apparent that you can not climb on top of the dome, nor can you expect it to support heavy snow loads.

Accumulated snow must be melted or shaken off periodically.

How many people could comfortably sleep in 20ft dome?
