Does the split king need two mattresses?

Yes. A split king base carries two twin XL mattresses, one per side, so each half adjusts on its own. A single king mattress will not work on it.

How much weight does it hold?

The European motors are rated for up to 800 lbs total. That is high for an adjustable base and covers most couples plus a heavy mattress.

Will it fit inside a platform bed frame?

It has a 3-inch profile and is designed to be platform-friendly, so it can sit inside many platform beds. Check your frame's internal height before buying.

What does the Bluetooth sync do?

It pairs the two halves so one iOS or Android device can control both sides together. You can still adjust each side separately.

How does the massage work?

Dual massage offers five wave patterns at ten speeds, with a 30-minute auto-off timer. Each side runs its own massage.

Is it a good upgrade over a basic adjustable base?

It adds split adjustment, massage, under-bed lighting and app control over a plain base. If you only need head and foot lift, a simpler base covers that.

Our take on the Southerland InMotion 2500 Split King Adjustable Base

The Southerland InMotion 2500 is a split king adjustable base, so each side of the mattress moves independently. It uses European motors rated to 800 lbs and is built for 200,000 lift cycles, with a 3-inch profile that works on platform beds. Dual massage with five wave patterns, ten speeds and a 30-minute timer, plus under-bed lighting and Bluetooth sync between the two halves, put it alongside feature-heavy bases from Leggett & Platt and Tempur-Pedic. It suits couples who want separate head and foot positions and a low-profile frame.
