An eco-friendly Loom & Leaf memory foam mattress from Saatva has been delivered to the St. Charles Borromeo Seminary in Philadelphia where Pope Francis will be attending the World Meeting of Families later this month. The queen-size mattress is made in the U.S.A. and sold exclusively online for $999. (The mattress for Pope Francis was donated by Bedding Industries of America.) Covered in organic cotton, Saatva claims the Loom & Leaf is a “healthier, greener, memory foam mattress.” Consumer Reports hasn’t tested the Loom & Leaf but we have tested another mattress from Saatva as well as two dozen memory foam mattresses from other makers.

The Best Memory Foam and Innerspring Mattresses

The top memory foam mattress from Consumer Reports’ mattress tests is the Novaform Serafina Pearl Gel, $800, sold at Costco. In our tests we found that it offers very good support for both back and side sleepers, and stays pretty stable when one partner changes sleep positions. Scoring almost as well was the Brooklyn Bedding Cool Symphony, $1,250, which is better for side sleeping than back sleeping and is also very stable. Third on the list is the Serta iComfort Savant EverFeel, $1,575. The Serta is better for back sleeping than side sleeping and just as stable as the other two. Our 11 top-pick memory foam mattresses range in price from a $470 Sleep Innovations model to a $2,750 Comforpedic.

The Saatva mattress we tested is an innerspring, the Saatva Luxury Firm Euro Pillowtop, $900. Scoring a 60 out of a possible 100, the Saatva innerspring did not make our list of recommended mattresses. It was so-so for both back and side sleeping and only fair for stability. A better bet is our top-rated innerspring, the Sealy Posturepedic Hybrid Trust Cushion, $1,275. It offers better support for side sleepers than back sleepers but is very stable. We also recommend six other innersprings.

We also discovered the make of the popemobile that will ferry Pope Francis around on his visit—a modified Jeep Wrangler. In Consumer Reports’ tests, the 2015 Jeep Wrangler scored a 20.
