Hi hyperc,
While other people’s comments about the knowledge and service of a particular business can certainly be very helpful … I would be very cautious about about using other people’s experiences or reviews on a mattress (either positive or negative) or review sites in general as a reliable source of information or guidance about how you will feel on the same mattress or how suitable or how durable a mattress may be for you and in many if not most cases they can be more misleading than helpful because any mattress that would be a perfect choice for one person or even a larger group of people may be completely unsuitable for someone else to sleep on and reviews in general certainly won’t tell you much if anything about the suitability, quality, durability, or “value” of a mattress for any particular person (see post #13 here).
The Ultimate Dreams 13" gel memory foam mattress is a similar type of mattress with a similar firmness level to the Tempurpedic Cloud Luxe so if you have tested the Cloud Luxe in person and it’s a good match for you in terms of PPP (Posture and alignment, Pressure relief, and your Personal preferences) then the odds are good that your mattress will be a good “match” for you as well.
It also uses good quality and durable materials so you certainly made a great quality/value choice.
I’m looking forward to your comments and feedback once you’ve received it and have had the chance to sleep on it for a bit … and congratulations on your new mattress 
Phoenix
