Is the 6-inch Dreamfoam Essential good for side sleepers?

Mostly no. At 8 out of 10 firmness it gives little give at the shoulder and hip, so side sleepers usually do better with the 10- or 12-inch version, which is softer.

How firm is the 6-inch versus the 14-inch?

The 6-inch is firm, rated 8 out of 10. The 14-inch is medium soft, rated 4 out of 10. Thicker versions add softer foam layers, so firmness drops as height goes up.

What sizes does it come in?

Twin through RV queen. A King is also listed.

Does it need a box spring?

No. It is an all-foam mattress and works on a slatted frame, platform bed or bunk base. A solid, flat foundation is best for the thin 6-inch model.

Is it good for a bunk bed?

Yes. The 6-inch height keeps it low enough for most bunk rails, and the firm feel suits kids and teens.

Is the King a good buy?

It depends on the sleeper. The firm 8-of-10 feel suits back and stomach sleepers and bunks, but side sleepers and heavier adults should look at the thicker versions or a hybrid.
