<p>Hey guys,
Could someone tell me what kind of mattress is used in the Caltech undergraduate houses? I want to get one for myself.
Thanks.</p>
<p>Manufactured By: MBC Mattress
Model: Col
Prototype ID: 53275B
Size: Twin XL</p>
<p>That’s what the tag says. There are several different colors of mattress around, but most seem to be blue.</p>
