The Heavy DutySmartBase 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 over a foot of 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.

It semms well-constructed, with welds where other frames use screws or bolts. It also has some supporting crossbars to make it sturdier. We shall see how long it lasts, but it seems to be quite good after a month of my hefty son using it.

Sturdy and gpod construction

My daughter moved into the city and into a very quaint house.  Unfortunately, her queen box spring was too large to pass through either the staircase or window - I immediately thought about this Zinus frame. The Casey Metal Premium SmartBase frame is sturdy, easy to carry, easier to set up and compatible with a queen size mattress. AND the 18th inch base frame allows for extra storage underneath - so valuable in any 'tiny house'.  Thank you!

Zinus to the rescue!

Bought this a couple months ago to replace my old box spring and it had been a game changer! It's quiet, very sturdy & easy to put together. It fits within my existing bed frame and is just an inch or so higher but it's barely noticeable. Definitely better support for my hybrid mattress than my old box spring - which also means less back pain for me!

Game changer

Okay so this is the most perfect bed base I've literally ever dealt with. I cannot believe this is not the standardized requirement for all bed bases. I have some weird hangups about box springs, so I knew I was in the market for a platform-style bed. I didn't want to deal with something super huge like an all-wood construction, and slatted wood stuff from ikea felt like it'd be too flimsy. I'm not planning on living in my apartment for the rest of my life, and I wanted something I could pack up and take with me. Enter the Casey Metal Frame. First, setting it up took maybe 15 minutes, tops, and I did it by myself. Second, the height is incredible. The ability to store things under my bed is *amazing.* I live in a studio loft and storage is at a premium, so the extra space under the bed is incredible. Last and most importantly -- this thing is solid as all getout. It doesn't creak, it doesn't squeak, it doesn't wiggle. It feels as sturdy as laying the mattress on the floor itself. I absolutely love the heck out of this bed base, and I feel like it gets a lot of airflow which I hope will help extend the life of my mattress. As a bonus, my roomba has zero problems cleaning under it as well.

So yeah. I love it. It's solid and I have no complaints.

I'm never buying a different bed base ever again.

I purchased this frame for a kid's room. It is soooo tall! I can store so many toys under this bed it's rediculous! It is tall, so the kiddos need a stool to get up on it. My memory foam mattress did slide a lot on this frame. I purchased 3 rolls of gripper cabinet liner and zip ties at Dollar Tree for a total of $4 and put it on the frame. The mattress no longer slides. 
It's light weight but sturdy and doesn't wiggle. It was incredibly easy to put together. 
Shipping was fast- I got it in three days. 
I did purchase the corresponding headboard/footboard brackets, but have not attached them as of yet.

So much storage space!!!!

I pickup this frame  Feb.19. the frame is easy to assemble no tools needed.
the frame is very sturdy, with lots of room for storage under it.  we assemble the bed frame the same day for a family member. there are enjoying it.

happy family

Was relocating my mother to a more accessible area of the house and prior to her return from an extended hospital stay. Before her accident, sh complained about her bed being too low. Brought her home today and she says it's just right.

Fit the Bill

This was very easy to set up and secure. Very sturdy. The ONLY PROBLEM is that the mattress slides around on the bedframe...there are no raised areas on the bedframe to hold the mattress in place. Every couple of days, I have to shove my kingsize mattress back into place on the frame. This is quite frustrating. Other than the sliding problem, It's a great product.

Only ONE problem...

sturdy and exactly what i needed at a fair price but on one end the bracket arms  were a tiny bit too short so one set of legs left unsecure - not happy and didn't want hassle of shipping back - used gorilla tape and secured the legs and is fine for use - except for this major flaw the frame is very good and would have gotten 5 stars.

major flaw

Was specifically looking for a bed frame that doesn't squeak, but unfortunately this one still does. I've tightened all the screws as much as possible, but it still makes noise when moving around. At least it hasn't broken yet, but then it's only been a few weeks.

Wouldn't recommend
