What does the E255 do that a basic adjustable base does not?

It adds Zero Gravity and anti-snore presets plus two memory positions you set yourself. Basic bases usually offer only up and down buttons.

Can I use it without the legs?

Yes. With the legs off it sits at zero clearance, so it can rest on a platform bed or slats. That gives the lowest possible profile.

Does it work with any mattress?

It works with most mattresses, including memory foam and hybrid. Innerspring mattresses bend more easily if they are flexible; very stiff or heavy mattresses may resist articulation.

How much weight does it hold?

The base is rated for 750 pounds, which covers most couples and heavy mattresses.

Does it have massage or USB ports?

No. The E255 focuses on positioning: head and foot lift, presets and memory. Massage and USB charging are found on higher Malouf models.

Can two people set different positions?

No. It is a single base with one head and one foot section, so both sides move together. Couples who want separate positions need a split configuration.
