Frequently asked questions

Is a 6-inch mattress thick enough for adults?

Yes, for lightweight to average-weight adults (under 200 lbs). Heavier individuals may need at least 8-10 inches for adequate support. It's great for kids, teens, and guest rooms.

It depends on the model. Plush options like the Saatva Rx 6" provide pressure relief. Firmer models may not contour enough for side sleepers, especially those with wider hips.

How long do 6-inch mattresses typically last?

With proper care, they last 5-7 years. Hybrids tend to outlast all-foam models. Rotating regularly and using a foundation can extend lifespan.
