Customer feedback highlights a good fit, soft feel, quiet operation, and reports of spill protection.

The listing describes a TPU-backed waterproof design, but that claim does not resolve the differing customer experiences.
Positive themes
- Customers are reported to appreciate the fit, softness, and quiet, non-crunchy operation.
- Some customer feedback reports successful protection from spills.
Mixed feedback
- Customer experiences with water resistance differ, with some reporting effective protection and others reporting that the mattress became wet.
