Hi ekoretz,
Just in case you haven’t read it yet … the first place I would start your research is the tutorial post here which has all the basic information, steps, and guidelines that can help you make the best possible choice.
While it’s true that SleepInc (owned by the same owner as Corsicana) purchased most of the IBC assets after their bankruptcy (see here) … this doesn’t mean that their mattresses will be the same outside of recycling the name and it’s always a good idea to make sure you do some careful and objective testing for PPP to make sure that the mattress is a good “match” for your body type and sleeping positions and to make sure you know the specifics of all the layers in the mattress so you can make sure there are no obvious weak links in the mattress. This would apply equally to when the mattresses in the IBC Europa line were available and when you are purchasing a mattress now. The brand name or the name of the model makes little difference because a mattress is only as good as its construction and the quality of the materials inside it regardless of the manufacturer’s name on the cover and knowing the quality of all the layers and components so you can identify any weak links in the mattress and make more meaningful comparisons with other mattresses is an important part of any informed purchase.
The IBC Europa line had many mattresses including several versions of the Intrigue model which included two 3.5" microcoils and some 5 lb memory foam (see here as an example) vs the Corsicana Europa which has one 3.5" microcoil over a polyfoam base layer and with a 1" layer of memory foam and a 2" layer of polyfoam on top of it. The listing doesn’t include the quality/density of the polyfoam base layer or the polyfoam and gel memory foam layers on top of the microcoil (which are especially important in terms of the durability of the mattress) and I would want to know this before considering it. While the microcoil is a good quality component if the memory foam or polyfoam on top of it are lower density then they would be the weak link of the mattress and I would avoid it unless you can confirm the quality of the layers. I would use 4 lb density or higher as a minimum guideline for the gel memory foam and 1.8 lb density as a minimum guideline for the polyfoam. If only the 1" of gel memory foam is below the guidelines then it wouldn’t be as big an issue in terms of durability if the polyfoam was good quality/density.
