Although I did not like the notion of the multi level supports, in the end it didn't matter. Solid, quiet, and well finished for the price. Packaged well in a surprisingly small box for a king frame. No brainer, no instructions necessary assembly takes about 1/2 hour. The under space is greatly appreciated. I purchased it for the ultimate Perfect Cloud Elegance Gel-Pro 12 Inch Memory Foam Mattress (King Size) - Amazon Exclusive Model Featuring Luxurious Fabrics & Double Layer of Visco Gel Cool Design - 25 Year Warranty reviewed separately - great combo with a ridiculous amount of due diligence. DO NOT USE YOUR OLD BOX SPRINGS FOR A MEMORY FOAM MATTRESS! I did not want wooden slats or the wire frame versions. I was not going to mess around with this investment. The packaging on my mattress said to place it on a flat surface or on bed slats not more than 5" apart. These narrow 3/4" square tube slats are 5 &3/4" apart, so I was suspicious. I experimented for review purposes. The photos were taken from below the bed while my wife was lying on it. You can clearly see the scalloped sagging between the "slats" and the foam coming down to the lower supports. I suspected this ahead of time so I got 2 sheets of 1/4" Luan. Its like paneling - very light, stiff yet flexible. They will cost you about $30. Have the store cut them for you 37&3/4" X 78&3/4" and they will fit within the perimeter of the king frame. Just round the corners a little. I used black Gorilla tape to secure it in a dozen or so places. It matches very well - not that you will ever really see it again. I definitely felt increased support and have the peace of mind I'm doing the right thing for my investment. The mattress I got has a "rubberized" non-slip bottom and it is actually very difficult to slide on the platform. Yep- even so I gave it 5 stars. I could not find anything better for my purposes and I'm very pleased with the end result. ... show more

Ok, I hope this review can help someone that was like me. There are a lot of reviews that are for the Zinus brand bed base but for different models. This review is for the Zinus 14 inch Elite Smart base "Big and Tall". You can see each base model on the product description and compare them. With that being said, do not get it mixed with the 18 inch or other 14 inch models. This model is for the "Big and Tall" and it's added feature is extra stability and weight limit of 4,000 lbs. Now, my wife and I are not big and tall at all, lol. We are actually not even close to that, but I wanted the extra stability in the frame after reviewing other customer reviews showing how the frame began to bend on them. Look at the product pictures and you will see that on the Big and Tall frame there are extra thick beams throughout the frame, whereas the other frames have more of a wire going throughout the inside. Other reviews have showed those wires bending on people. I didn't want any chance of that happening, so I chose to go with the more thicker beamed framed. I'm glad I did because this frame is a tank solid. I've only had it for a couple of weeks now, but I am VERY - VERY PLEASED with my purchase. Time will tell if any squeaks will start, but right now absolutely quiet. No squeaks at all. Now the big topic everyone is concerned about, the storage space under the frame. This frame has at least 12 inch in height storage space. You might be able to squeeze a little more than that but you might have difficulty pulling out your container. I've included a photo with a 12 inch high tote under the frame. When I was in search of a base, I really wanted the 18 inch high Zinus frame, but I was concerned of the stability of the frame. From other reviews showing of the wired typed of frame has bent for others, I was also concerned with going 4 inches higher on the frame legs on 18 inch will make ghe frame less stable. I assume the higher you go, the less stable the legs are on the frame. I don't know if that is true, but the 14 inch frame with the solid bars throughout is very stable and still comes with excellent space under the bed. You can go 12 inches high and be safe, and you have the entire rest of the bed space for storage. My wife put together the frame and mattress HERSELF while I was at work. I guess she couldn't wait but she did an awesome job and it's not difficult. My entire king size bed came in 2 boxes from Amazon. The frame and mattress. We are using a "Classic Brands 14 inch Cool Gel Memory Foam" king size mattress that we couldn't be more pleased of. These two items together are a match made in heaven, lol. Although we will be putting some flat plywood between frame and mattress just to give more of a flat surface for the memory foam. I don't know if it's necessary because when I look under the bed, I don't see any substantial sagging. It looks fine, but I just want to be safe. At the end of the day, the frame is awesome and a great idea. Very sturdy, quiet, easy to put together and easy to move around. I am very pleased with my purchase and I highly recommend it. ... show more

We have ordered 3 different ones and they never disappoint. Using for several years now and holding up great. Better design than the old flimsy metal frames with the box. They also allow for some under bed storage and the tallest design we were able to slid a dog bed under it and our 60 pound dog fits comfortably under the bed (he loves it). We have spiral staircase in the house and this design also enables us to move a bed frame up or down the steps since it can come apart and easily be reassembled. ... show more
