How comfortable can you make a futon?

My son wants a futon for his college apartment bedroom. It will serve as his bed and a place to hang out. I am worried it won't be comfortable enough for sleep. I saw a 6 inch memory foam mattress for futons. Does anyone know how comfortable they are or how well they hold up?

I slept on a futon for 4 years through college and I can tell you the mattress is KEY! If you do not skimp on a futon mattress, you can have a great place to hangout and to sleep. I paid about $250 for just my futon mattress, and it was great for the four years.

What was the name of the See N Say toy that featured different sofas and chairs as characters (early 80s)?

I had a See N Say game when I was a child that featured a number of different types of furniture. I know it had a loveseat and possibly a porch swing, but it was all sofas and chairs. Does anyone remember this or know what it was called? I was a child in the early 80s so that's when it would be from.

Is 100% cotton poplin suitable for upholstery for furniture (for a little kid sofa chair)?

Want to be sure before I order the material.

Should work fine. Would not recommend it for a full size sofa/chair.

can it rest on it? i cant figure out if theres like a hole there where you need a boxspring and a real mattress or if theres like boards there??? how can i find out

In the description in the “good to know” area, it says it is a slated bed base. You would need to put slats under the mattress. I personally would recommend putting a sheet of plywood over the slats to provide a solid bed base so the futon doesnt work it’s way between the slats.
