This heavy-duty box spring delivers a clean, practical design to provide a reliable foundation for your mattress setup. It features a steel interior framework that helps prevent sagging and wear over time, extending the useful life of your sleep surface. The clean-lined profile is wrapped in a fabric cover, creating a neutral backdrop that coordinates easily with your choice of bedding. It easily rests inside your existing bed frame to help distribute weight evenly across the base while minimizing motion transfer. Plus, its folding design makes it easy to move through tight hallways or store away when it's not needed.

Perfect for my 14” tall mattress that I also received from Wayfair! Previously, I ordered an extremely expensive mattress and was so disappointed with it, but already had the bedtime that needed height-so this was a perfect addition! It took 30 seconds to unfold, set in the frame, and zip up the cover. It’s super heavy duty and my heavy mattress doesn’t sag at all. I would certainly recommend this product if your mattress needs support and a little boost!. Crystal. Springfield, IL. Wed Oct 14 2026

Upgrade your sleep experience with this zero gravity adjustable bed, designed for personalized comfort and support. It comes with a wireless remote to change the metal base's head and foot positions. The remote also features preset buttons and a built-in flashlight. Built-in USB ports provide added versatility, while the massage settings help relax muscles and reduce tension. We love how the zero gravity function promotes better circulation and pressure relief, so it's great for all types of situations. With a sturdy steel frame and whisper-quiet motor, it reliably holds a mattress of your choice (sold separately).

This is NOT an off brand adjustable bed frame, it’s made by Mlily who make quality bed frames. It uses two whisper quiet lift motors, a name brand controller module, four earth shaking vibration motors and a heavy duty frame. We purchased two king bed frames and both had FOUR position legs(3” each) and a LIGHTED remote control(see images). You will easily pay twice the price for a comparable bed frame anywhere else with the same features. My wife and I(58 and 60yo) were able to separate the two king bed frame sections at the three hinge points with a metric ratchet and wrench and unplug three quick disconnects in order to half the weight to 100lbs each and bring them up a flight of stairs, then reconnect everything on the second floor, this process saved our backs and cost us an extra fifteen minutes tops. Installation was super simple and the remote was already paired to the frame. As an engineer, I’m seldom impressed by the current “quality vs cost” of items being produced, this bed frame was the exception!!. Brian. Jackson, NJ. Sun Jun 07 2026
