Is a 6-inch memory foam mattress thick enough for an adult?

It works for lighter adults and side sleepers who like a firm feel, but heavier sleepers will likely feel the base through it. For nightly adult use, a 8- to 10-inch mattress is usually a better fit.

Does the gel foam really sleep cooler?

Gel infusion can help with heat compared with plain memory foam, but a 6-inch all-foam mattress still traps some warmth. A breathable protector and a firm foundation help more than the gel alone.

What size frame does it fit?

It is 39 inches wide and 75 inches long, the standard twin size, so it fits a twin frame, bunk bed or trundle. It also suits adjustable bed bases.

Is it good for a kid's first bed?

Yes. The low profile suits bunk beds and small rooms, and the CertiPUR-US foam avoids many regulated chemicals. The 2-year warranty is short, though, so expect to replace it sooner than a premium mattress.
