Which one
If you cannot measure, the longer window is the one that protects you: Pillow Cube at 60 nights against Helix at 30. On a fit problem you are buying the right to be wrong.
Only one of these can be checked before it arrives. Pillow Cube publishes 5", which suits Firm 5.4–6″, Medium 6–6.8″, Soft 6.8–8″. Helix publishes no height at all. Neither pillow adjusts, so if the height is wrong there is nothing to remove and nothing to add — which makes an unpublished loft on a fixed pillow the one omission that cannot be worked around.
