  • UPDATE *Taps mic* “THIS ONE IS FOR THE FAT GIRLS.”
Color: Grey Size: 9 Inch Style: Queen
**UPDATE** I’ve had this frame for 2.5 years, and over the past couple of weeks my mattress has been sagging slightly, and when I moved the frame to vacuum I heard a clanging sound… Assumed that—most certainly—I had finally broken this frame due to my weight. After I lifted the mattress to check out the damage, I was shocked to find that the center support had merely fallen off: from my most recent move, it appears that the movers didn’t tighten the support center bolts when reassembling the frame! Ten minutes of realigning bars and tightening bolts, this frame remains good as new: a totally unexpected delight. I’m updating this review laying on my mattress, once again fully supported with no sagging… if you’re reading this? Buy it. An exceptionally made product underscored by sustaining no damage even without the center support beam attached for a spell. (Former Review) I have elected to sleep with a mattress on the floor for the majority of the past seven years after three ill-fated moments featuring a bed frame from IKEA (particle board snapped clear through when I sat on it), one of the so called “heavy-duty” fold out frames (endless creaking), and my last investment in 2015 of another “heavy-duty” frame where the slats cracked literally on the first night. I currently weigh ~400+ pounds, and most frames cannot handle the static weight of a singular body of this mass plus the weight of a mattress due to stress points and poor manufacturing. I’ve waited a couple of months to provide feedback on this piece... let me tell you, this frame is THE ONE. 1) There is no creaking or squeaking. 2) The foundation is supported 360-degrees with welding, so the weight distribution is phenomenal. 3) The middle bar and legs have not cracked, bent, or warped (likely due to the exterior construction), and at the 30-day mark when I removed the mattress to tighten up the bolts for preventive maintenance, they had hardly loosened at all, indicating very little frame motion impact with my body weight. I live with a disability that is physically kicking my a** due to balance and coordination issues, and the ability to get in and out of bed easier and safer—vs. when the mattress was on the ground—is life changing. It’s so much nicer to leave rehabilitative physical therapy and crawl into a bed that is higher off the floor... and not have to worry about something snapping. Don’t hesitate. Assembly was a breeze... and it looks good, too. ... show more

  • Keep the 3/16th hex key it comes with!
We’ve had this bed frame for about nine months now and we’ve used it under our Indigo brand king sized mattress. Our Indigo bed was one of those “bed in a box,” beds so it unfolded out perfectly onto the frame once I assembled it. The king sized mattress fits perfectly as well. It was fairly easy to assemble, maybe took me an hour or so by myself and the slats were so easy to just pop in. I HIGHLY recommend keeping the little hex key tool that it comes with to screw it all together but if you misplace it like I did, the size was 3/16th and I was able to get a $5 pack of multiple sizes of hex keys from my local Home Depot. I’m fairly petite (110lbs) while my boyfriend is about 170lbs and this bed has stayed very sturdy in the last nine months. We started noticing tiny creaks within the last few months but just moved last weekend which involved transporting the frame on its own in the bed of our friend’s pickup truck (it was a short-distance move). After sleeping on it for a week moved into our new place, I’ve noticed very loud creaking throughout the night as we toss and turn which led me to buy another hex key just to tighten up each screw. I’ve rolled around on it and it’s once again very quiet and study! Keep the hex key in case it starts to creak, it just needs a little tightening! Great subtle style as well. Love the bed frame. ... show more

  • Initial Review
Color: Grey Size: 12 Inch Style: Queen
Was finally able to ditch my 7 year old fiber board frame from another store and went searching for a new one on amazon. As two large people 6'1 250 and 5'8 300 we needed something sturdy for sure. This bed was well reviewed for large people, for a simple foundation and for ease of set up. I can definitely agree with all of those statements and must say the lack of squeaking, support of the mattress, the smooth corners and the size are perfect for our queen size mattress. Read other reviews and didn't peel the anti slide sticker covers off due to the challenges they present and we had no issue with our first nights sleep. I will update my review in the future if any negative issues arise. For now, very pleased ... show more

  • Great for price
Color: Black Size: 12 Inch Style: King
I am 350 and this lasted over 2 years without issue, it does require tightening up from time to Time but, it supported me and my wife, even my kids at times. Light weight easy set up. Only down fall I wish it last longer

  • STURDY
Color: Black Size: 12 Inch Style: King
I have a king bed and this fits it nicely. It is has very HEAVY pieces and was a little tough to move the box all by myself. Assembly wasn't too bad and the white strips are covering anti slip straps for the bed. It does slide some on my wood floor but I love the sturdiness of it. I also am not small and can handle wrestling matches on it 😏 I had my box spring initially on it, but then removed it due to needing a step stool to climb into my bed. But I absolutely love this frame and it is very plus size friendly. ... show more

  • Just received...
Color: Black Size: 9 Inch Style: Queen
Just received and assembled this today, so this review is based on initial impressions and i will update at a later point in time if any issues arise. First, BOX is long and heavy... one person could do the set up however. The unit came with printed instructions and assembly was a breeze, as part are labeled well and all screws and a wrench were provided. It took my husband about 30 mins (if that) to have this together, and that was even stopping once. After going back around and checking that everything was tight and placing the slats on place, the new memory foam mattress was installed. The bed seems sturdy at this point, I didn't notice any noise when sitting down, getting up, or moving around on the bed. Again, if any of this changes, I will update this review. I also wanted to add that this 9" base seems to be a perfect height. Since the mattress is 12" thick, total height is 21" and that hits me at the knee (I'm 5'4") when I am sitting on the edge of the bed. It is easy to get in and out of. I would recommend this product to others. ... show more
