Hi memoryfoamoverlord,
Most of the members on the forum that have purchased it (and Brooklyn Bedding) have said it is “slightly” firmer but still in the quite soft range.
No … I’ve never seen the Ultimate Dreams or slept on it so I really have no idea (outside of it being a similar comparison to the Cloud Luxe and the Rhapsody). I do know though that they are working on a mattress that will approximate the Rhapsody.
Some of the better online memory foam manufacturers I’m aware of are listed in post #12 here. Some of them have mattresses that approximate some or all of the tempurpedic lineup either in feel, quality of materials, design, or all three (see post #2 here).
