## Overview

The Zinus Premium SmartBase is a queen-sized, heavy-duty steel mattress foundation that replaces the need for a box spring and traditional bed frame. Standing 18 inches high with 17 inches of under-bed clearance, it offers ample storage space while supporting up to 750 pounds. Tool-free, quick assembly and a folding design make it perfect for easy setup and moving. Finished in sleek black alloy steel, it promises a quiet, durable, and minimalist platform backed by a 5-year limited warranty.

## Description

The Heavy Duty SmartBase® is a mattress foundation even stronger than your Monday morning coffee. Engineered precisely with heavy duty steel and unwavering support from multiple points of contact with the floor, this frame is built tough enough to support up to 3000 lbs of evenly distributed weight. With a frame this sturdy, you can bet that your mattress will be optimally supported for the long haul with absolutely no sagging. Its metal platform effortlessly supports your foam, spring or latex mattress without the need for a box spring. Built with valuable underbed space for extra storage, this handy frame also includes practical features like recessed legs and plastic caps to protect your floors. And although the last thing you’d expect from a frame this tough and functional is tool-free assembly, that (and a 5-year worry-free warranty, no less) is exactly what it comes with. Easily unfold the base, extend the legs, use the easy locking system to secure everything in place and voila! You’ve got a substantial mattress frame in less time than it takes to brew that pot of coffee.

Review: Very sturdy bedframe with no noise - These are perfect for a tall young adult man. It’s sturdy, easy to set, and no noise or squeaking. A great item and great price.
Review: Updated: Full review two years later! (Preliminary Review: Unboxing and set-up) - I will write a full review of this bed frame after I have used it for a while but wanted to give a preliminary review first. I've had it for about a month before setting it up (waiting to get a new mattress and get rid of my futon), so it's been in the box which was on the large side but was able to tuck it away in my kitchen for a few weeks. I live on the third floor of an apartment building and while the box was a bit bulky and heavy, I was able to get it up to my apartment by myself with no problem. I'm a big girl with a not-so-great back, but it was definitely manageable. Having forgotten anything I read in the reviews about assembly, I was expecting a cumbersome set-up job with a lot of little parts and pieces and metal clanging around as I jostled this frame around my tiny little one-room apartment. I was pleasantly surprised to find that the frame consists of two separate pieces that fold out, and are then joined together by two screws in the middle. THAT IS IT!! Putting it all together took me about 20 minutes. Probably would have been less if I had more room and wasn't having to rearrange other furniture almost every step of the way. I have my new mattress set-up on the frame and expanding now (I got a Tuft and Needle original mattress which is a little longer than the frame, so not sure if that's a frame issue or mattress issue, but hardly noticeable) and was impressed with how easy it was to move the frame during the unboxing of the mattress and how lightweight it is. I am honestly a little apprehensive about the two pieces of the frame staying together with two screws as the butterfly bolts don't screw as tightly as I would like. I anticipate maybe having to find a washer or nut or something else to just make sure the fastener doesn't come off, but that's super easy so I'm not too worried about it. I did really appreciate that the hardware (two long screws and two butterfly bolts) came in a package together so it was easy to set them aside and not have to worry about them flying around. Oh! I also really appreciate that the frame came with two non-slip pads that are often used for carpets. That will hopefully help prevent the mattress from slipping off the frame. The storage capacity underneath this frame is AMAZING! Because there are two braces in the middle of each section, the storage underneath is in two sections divided horizontally but I can fit so much stuff under just one section because of the height which I am loving in my small apartment. The stuff from under my futon is now under ONE section of this frame, leaving me so much more room to store things that have been getting in the way. I will give it a full review after sleeping on it for about a week, but I'm optimistic that I will be highly satisfied! ****UPDATED REVIEW**** Two years later I am back to finally update this review! And two years later I am still 100% satisfied with this bed frame! When I moved last summer (Aug. 2020), taking this apart on moving day was a snap and it took me five minutes to set it up at my new place. I had previously been worried about the two screws joining the sections coming loose but that has been a non-issue in the last two years. I eventually added a bed skirt to help conceal the totes and things I have underneath, but the storage space has been such a game-changer for me, even when I moved to a bigger apartment. The frame is super quiet and holds up with some company in the bed, so no complaints there! ; ) I really cannot recommend this frame enough, it is one of the best desertcart purchases I have made. If you're looking for something sturdy, easy to put together (seriously only like FOUR PIECES in total!), excellent under-bed storage, and durable, GET THIS FRAME!
