Gel Memory Foam Sofa Bed Mattress | Replacement Mattress for Twin Size Sleeper Sofa and Couch Beds

Can you use it for a bed? In stead of a sofa bed?

What type of cover comes with it? Zip around, fitted w/elastic corners etc.

Dose it come with cover or just the fome?

Is this mattress firm or do you sink into it and it conforms to your body as you lay on it? I'm wanting to use this as a floor bed for my 1 year old
