Queen Size Memory Foam Mattress - Like New Condition - $450 (redwood city)

Purchased for full price in September of 2022 and used until January 2024, so they are just over a year old.
Serta iSeries Hybrid Medium Queen Mattress.
No rips, stains, or tears.
Always used a mattress protector.
Smoke-free home.
Pets in home but not allowed on the bed.
Queen adjustable base.
Still under warranty but stopped working a few months ago.
I think it’s an electrical issue that can be sorted out with customer service.
The base folds up for easy transport.
I'm selling because I’m upgrading to king size.
