Sleep Science Q-Series Plus Tilt Adjustable Base

Best Pillow I bought a second one for my vacation home.

Very comfortable

Well You Asked, hope this helps...

We are loving our Split King bases. 5 Stars We replaced a conventional mattress/box spring with these. We installed them in our existing King size bed frame. The fit is very good, once I discovered the bed frame was not square. Shipping: The shipping container was damaged, the bases were not. Installation of the first one: 1. We needed to only use three spacers. Hint don’t remove the felt adapter from the bottom spacer. Just take a spacer from the top. The felt adapter strips and will not screw back in. 2. The power hook-up doesn’t match the instruction booklet. The 9vdc battery adapter does not go inline. It replaces the AC power supply during power failures. 3. There are no wing nuts supplied as the mattress guides are friction fit. I used a small mallet to tap them in. Installation of the second one: Having learned the second one went fast. No issues. -Jim & Jeanne-
