Hi Watson123,
As you know one of the attractions of the “one choice fits all” style of mattresses is that they simplify the buying and decision making process which can be very attractive to some people and may be one of the most important parts of their “personal value equation”. With any retailer or manufacturer that only offers a single mattress though you will find that they will be the “best” match for a relatively small percentage of the population, a “good” match for a larger percentage, an “OK” match for a larger percentage yet, and for those that it isn’t a “good enough” match … they have a great return policy that lets you start all over again with choosing another mattress with little risk outside of the time you spent trying the mattress or returning it.
As Sheep123 mentioned you will notice changes over the course of the first few weeks as your mattress “breaks in” and you go through the adjustment process for any new sleeping surface and there are some suggestions in post #2 here that may be helpful as well (some of which sheep123 also mentioned) but if you give it a few weeks and your Tuft & Needle mattress (or any “one choice fits all” mattress) just isn’t turning out to be as suitable a choice as you hoped for in terms of PPP then you have the benefit of a great return policy that lets you “try again” with little risk.
I’m looking forward to seeing how things progress for you over the course of the next few weeks.
