Hi Tomcat,
Most of your “should I” questions are more about preferences and when you are down to final choices between good and good then which mattress is best for you would really depend on the parts of your personal value equation that are most important to you and your own “educated best judgement”.
Based on your post … it seems that you are leaning towards memory foam over latex which can certainly help narrow down your choices. As you probably know from your testing … they are very different materials.
These are decisions that only you can make based on your own criteria, your local testing, and your more detailed phone conversations with each online manufacturer you are considering. There is more in post #9 here about the different ways that one mattress can “match” another one. I think it would be fair to say that the quality of the materials and the comfort/pressure relief and the support/alignment of the Select Foam Regalis would be very similar but that the “feel” which is more subjective would be a little different because of the differences in the type of memory foams they use. This would be fairly typical for some of the other online memory foam choices that compare one of their mattresses the Rhapsody as well. A forum search on Select Foam Regalis (you can just click this) will bring up more information and feedback from other forum members.
Select Foam itself is a member of this site which means that I think highly of them and they are happy to compete with the best in the industry. Like the other members of the site, they have great quality, value, and service but in their case they have also had a few issues from time to time when there were some delays or issues after a sale that weren’t dealt with as quickly as I would have liked to see but these are more exceptions than the rule. You can see a couple of recent examples of after sales service issues that are taking longer than they should in post #69 here and this thread.
Like some of the other online manufacturers or retailers that are in the online memory foam list … they have a very good return policy that pays for shipping both ways (original shipping and the return) which certainly lowers the risk of an online purchase. You can see their return policy here. As with any online mattress purchase … I would make sure you talk with them in more detail on the phone as well because they will be the most reliable source of any specific information you need about their mattresses.
I also wouldn’t worry too much about their “sale” or let it create any false sense of urgency because their sales are ongoing although they do rotate between different combinations of similar benefits.
