I hate not being able to test it out and get a feel for it but I guess that is why they have sleep warranties and Costco is the best for returns. After sinus surgery and wearing mouthpiece to prevent my jaw from collapsing my airways it is much better but still stuffiness issues which I would hope raising bed a bit more with an adjustable base may help.
It is still comfortable and supportive and I have top end slightly propped up because of sinus stuffiness since I have had problems which contributed to sleep apnea. I had to add 2inch mattress topper(Costco) as had pressure points on hips and shoulder(side sleeper).
On one hand I will need new mattress in few years as our Springwall queen firm is over ten years old.
