Question: Is this sturdy enough to hold a queen mattress? I'm worried about the mattress sinking as there are only 3 rods for support. Thanks guys
Document: We set this bed frame up for a queen mattress in our guest room. The first time it was sat on it collapsed. The support for one of the wheels completely bent over on itself tipping the bed suddenly into an inclined position. This item is not sturdy enough for even occasional use and was not only completely disappointing, but dangerous.
I'm torn. The first set I ordered - 5 stars. Second set 3 stars. Please see my original and updated reviews below.I bought this to replace one my parents have had forever and I had this set up and in place in no time flat. Very easy to set up and the extra support beam and feet on it supports the mattress better, which is good for the mattress and your posture.
This frame well exceeded my expectations! I needed a sturdy frame for a queen size bed, and this is one heavy-duty, sturdy frame.I have already recommended it to one family member, and if I ever need another bed frame, I'm getting this again.Thanks for a great product at a great price!
I received my frame within 3 days of ordering it. It came in a nice sized box that wasn't too big. The instructions were RIGHT on the box, a label covered part of it, but I just peeled it back and figured it all out. I'm a female! I put together this bed by myself with no help at all! I even was able to attach a headboard to it! I feel so handy hehe.The bed is sturdy! The extra support bar is really nice.
When the box showed up I thought there was no way this was the right item..long enough but surely not everything was in there. But yes it was. It took me less than 10 minutes to put this together and I'm very impressed with the durability. The only thing is that the locking wheels are a joke. They just don't lock! I'm not too worried by this since my sleeping area is carpeted but I imagine that on hard wood floors this sucker would just be rolling around all the time.
Bed frame is sturdy enough for the job. It is for a head board only. Strongly recommend the foot board extension regardless. Queen mattress will flip if you sit on foot of bed without it. If putting a foot board on, you will need the extension anyway. Frame is about 14 inches short of coming to end of queen mattress.
I'm 220 lbs. So i could lose a few, but I personally do not excede the weight limitations of this frame. My wife and I currently live in different states due to recent work changes and so I bought this frame to lift the new mattress set I got for the new place I'm in. So most of the time it's just me and then something it's both of us. Still, should hold average adults.The frame failed within a month of having it.
The product was ordered, and delivered within 3 days!Easy to set up, nice HEAVY construction. The factit not only has wheels (so I can move it to clean)but the addition of a center support makes this anoutstanding product. I had it together and readywithin minutes. I'm so glad this is the frame I selected.
This frame can adjust from twin to full or queen using the middle bar. I just needed it for twin and it set up without problems.I did not need  the middle bar so set it aside but it appears to be a sturdy frame. One section that attaches to the headboard was a little bent but we were able to work with it and although the frame looked crooked, once the mattress set was  placed on it it straightened out. Good value, I'm happy with it.
Feel confident purchasing this item from this seller. It is just as it says and the cost is half as expensive to comparable items. This is nice too because it actually will adjust to fit a queen, full and twin. Plus has rolling wheels that lock into place and a middle support bar. A tip: It was easier to put together with another person because I'm using it for a queen and it is big when maneuvering by yourself. Very sturdy.
Answer: definitely, I have a queen set on ours and it is quite sturdy.....no middle sag.
