Bottom-Line-Up-Front: 4.8-5 very satisfied, young professional. I bought this for two reasons; the extra clearance underneath and to replace my Ikea Malm (pressed-wood frame) that was damaged in the Ellicott City flood in July 2016. Set-up is a tool-less breeze and this frame is silent. That is probably a result of how sturdy it is. I'm not sure if it is perfect, however, it seems perfect for my needs. The frame is tall enough that I can very easily vacuum underneath of it with my full size Shark Navigator. Two very small gripes which make this a 4.8-5.0. If you order on Amazon it does not come with the grip mats, but it is not advertised with them there like it is on Zinus' website, so I did not actually remove a star. And two, there was minor damage to a small plastic end-cap on one of the frame-halves I am certain that it is not a manufacturing/industrial material issue and only a result of shipping. Packaging is noticeably simple, which I greatly appreciate not paying for boxes and plastic I intended on disposing of, so it does come with risks like that.

I love this bed. I was indeed amazed how a king bed and frame hit into such a small box compared to the size of the bed. Mattress didn't even seem like it took long at all to reach its full size. Firm, but also like a marshmallow. The most perfect combination ever. Literally so happy I ordered this bed. My husband wanted a purple, but the quality of this bed along with price was too great to pass up.

This is our 5th Zinus mattress foundation purchase and we do think they're primary function is to help solve storage issues. And for that, they are superior. I just wish that before people make the purchase that there is some honest communication between manufacturer and buyers that this foundation will make your current mattress more firm. It does take a few nights to get used to. We had a firm mattress to begin with, and now it is very very firm. But we are still very glad with our purchase and obviously with 5 of the frames now in our home, much more pleased with how much extra storage area they have provided.

I love my 18'' smart base. I live in a studio in NYC and this base its perfect because I have plenty of space underneath for storage. its so simple to put together and is well built. I have an 10'' Inspiration Full size mattress by Signature Sleep. Best deal I have ever got from both company. Thank you both.

I started researching memory foam mattresses, because I was recently diagnosed with a chronic illness that causes global pain issues, and finding a comfortable position to sleep in had become impossible. My computer is smarter than me, noticed I was doing a lot of memory foam mattress searches, and threw me a Zinus ad when I was reading Yahoo. Thank you computer! I ordered the 18" steel bed frame - easy to set up, and the perfect height for storage underneath. The frame arrived on a Friday, and the shipment was marked online as "delivered"... but no mattress! A quick call to the shipper (Can't remember if it was FedEx or UPS) confirmed that the frame & mattress shipped separately, and the mattress was on its way. My mattress is a 14" cool gel memory foam (full size). Setting it up was a challenge (I live alone 75% of the time, so no one to help), but I gotta say watching the mattress decompress was one of the funniest/most entertaining things I've seen in a while. I wish someone had been with me to take a video! It started expanding the second I cut into the vacuum-sealed plastic, and was almost completely expanded by the time I finished cutting the plastic off. It went from pancake to POOF! in less than 10 minutes! It's also very comfortable to sleep on. When I lay down I can initially feel all of the pain points (neck, shoulders, elbows, hips, knees), but after a minute or two my brain goes "ohhhh... this is what support feels like" and I can relax enough to sleep. I'm already budgeting to replace the mattresses in the rest of the house with Zinus!

the ease of putting this frame together was just great. I tried to put together a adjustable frame together an fought for 2 hours and failed. took it back and ordered yours. Got it and 10 minutes later I was done my wife and just love it thanks for making it so easy

This bed frame is awesome! Easy to put together. I have to admit, the bed is way high! Need a step stool to get on bed. Didn't think it would be so high. I do love it but not good for someone who is handicap as I am but there is plenty of storage room for my underbed draws and containers. I would send back for a lower frame but I decided to keep it as I ordered all new bedding and bed skirt for it and it does look beautiful! I highly recommend! PS. My poor dog hates it LOL as she can not jump on and off the bed now without my help.

Was easy to put together and sturdy. I was a bit disappointed that one section was slightly bent (dented in). Does not really affect the integrity of the frame but I would have preferred an unbent one. The non slip pad was not included but that issue was addressed immediately and very quickly. Great product and amazing storage space.

Best purchase I ever made for my bedding. Purchased a king size one about 5 years ago. No box spring needed. Everything still sleeps like the first day I purchased it! I "LOVE" not having to fight with the slats falling off the rails!! Recommend buying!!

As soon as I started sleeping on my Zinus mattress, I forgot that it was new. I also forgot that I was supposed to think about whether or not it is comfortable and meets my expectations. I forgot because the mattress is so comfortable that it became part of my life immediately, like meeting a gold friend after a period of separation. I rarely think about this mattress because I am too busy enjoying sleeping on it.
