Hi kmiyashiro,
Does anyone have any experience with the 5in Tuft and Needle?
There have been a number of forum members that have ordered it but you will probably need to "sort through" a forum search on
Tuft Needle
(you can just click the link) to find the feedback about the 5" version among the 10" purchases. The earlier pages of the search results before they introduced the 10" version would have more feedback about the 5" version but I would keep in mind that each person can have a very different experience on the same mattress so I would be very cautious about using other people's experience as a reliable indication of your own experience on the same mattress.
How comfortable is it compared to a 10in mattress?
"Comfort" is very subjective and relative to each person but both the 5" and the 10" are designed to feel about the same. Because thinner mattresses become firmer with compression faster than thicker mattresses ... some people in heavier weight ranges will probably find that the 5" version feels firmer than the 10" version. Both of them are in the firmer range and would be a good choice for those who prefer a firmer mattress. In the end though the only way to know how "comfortable" a mattress will be for you will be to sleep on it and their return policy gives people that believe it would be a suitable choice in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) a chance to try it with little risk.
I want something that I can fold up and put in my closet since I'm in a 300sqft studio. How well does a mattress hold up to being folded every day?
Because it's polyoam it will tend to "spring back" if you fold it and wouldn't be the same as a typical futon made from natural fibers which can fold more easily. Repeated folding would likely have an effect on on the durability of the foam in the area of the fold crease and it would also depend on the sharpness of the fold crease (a rounded crease would have less effect on durability than a sharper crease). For storage it would probably be better to roll up the mattress and tie it up than fold it tightly on a regular basis but I would also talk with them to see what they think as well.
