Lull Mattress Review: Original All-Foam Testing & Lineup Context Restored
Yawnder’s Lull page had kept some useful copy but lost a much larger original review and model context. This rebuild restores the core hands-on conclusions without dragging old promos back in.
Original Lull feel
The original Lull was a straightforward all-foam mattress with a true medium feel in our testing. It was not radically different from other boxed foam beds, but it balanced pressure relief, motion isolation and support well.
Motion isolation
The all-foam construction kept partner movement low, making the mattress especially relevant for couples sensitive to motion transfer.
Cooling relative to foam
Lull used gel-infused foam and a breathable construction to keep the surface from feeling as heat-trapping as some older memory-foam beds.
Lineup expansion
Lull later added more premium foam and hybrid models. That matters because the original 10-inch all-foam Lull should not be treated as interchangeable with later Luxe/Premium versions.
Current-shopping note
Lull’s current lineup has evolved. Use the restored review for the original mattress’s feel and performance, and compare current models separately.
