Hi Mac

Sorry about the delay in response we’ve been incredibly busy!

Our lay gel topper is flat as we find the egg-box or castellated design can cause issues with uneven wear and as you said, makes the topper one-sided.

Laygel is a soft but responsive hybrid foam so really doesn’t need this design to work to its best.

Keeping it consistent ensures even wear and a flat sleeping surface.

If you need any more information please get in touch with us to assist.
