U-23 mattress problem, does anyone else have a problem?

[Macaroon]

Does anyone have problems with the 2019 u-23 mattress? I hit bottom and feel the plywood base after about 3 weeks of sleeping on it. The foam gives out and I can feel the plywood at my hips and shoulder.

Surprised you made it three weeks...I gave up on ours after one weekend and the resulting sore hip! Swap that cheap piece of foam out with one of the many replacements out there...many threads on opinions of which is best.
