Question: Does this bed require a box spring? i would be using it with a 12 inch memory foam mattress. I wouldn't be opposed to ordering more support planks from the factory, after the bed arrived.
Document: My only issue with this gorgeous bed are the support beams: they sometimes fall off the metal guard and hang down to the floor, causing my memory foam mattress to fall as well. Its as if the sides are bowing out. I will admit i do have a medium size dog who thinks he is small enough to squeeze under this bed (less than a foot of clearance), and pushes up on the boards, so maybe this is the issue.
Had it for about a year now and it works good for one person. I use a memory foam mattress on my bed. Easy enough for one person to put together, the reall issue can with the support wood for the mattress. You know the wood that runs horizontally on the bed to hold the mattress up from falling on the floor. Well the wood is a little too short for the bed causing it to snap past the metal braises and cause a huge dip in your matress.
To all those interested in purchasing this bed be forewarned. The support beams that ship with the bed are cheap bamboo planks. The center beam is supported by two THIN bamboom planks less than an inch in depth held in place by a single screw. For those that do not know what that implies, if the bed moves in ANY direction the center support planks give way. On my hardwood floors any movement causes the bed itself to shift, again putting pressure on the planks and shifting them.
And there was also some confusion with the last part of it. The odd metal pieces going across the bottom of the bed. They're weird and didn't seem like they were doing much of anything. Maybe that's my mistake, but I can't figure out their purpose.But otherwise, no outgassing for those of you who are concerned with that. It looks fantastic, I like not having a footboard, being I'm 6'3&#34;. Also the not having to have a box spring is nice.
*Test of time4 to 5 stars!After spending some quality time(been about 9 months now) with this bed frame I can confidently say it has so far performed excellently. I did end up purchasing a box spring only because I did not like how low the bed sat, but I still believe the box bring was not necessary. After 9 months of use it has not given way in any area.
For one, the bolts connecting the headboard to the frame were a bit too short, so I had to buy a larger bolt set. As well, the legs for the support beam were a full quarter inch short. What this had done was bend the support beam and warp it, and bent the slats excessively. Again, I had to go out of my way to come up with my own solution for this one.
In two of the three Tvilum orders I made, boards had broken corners or chipped edges when they arrived. The good news is they will send you replacements, but it's gonna take a few days to ship, so don't order if you are on a time crunch. Didn't have any trouble with the replacements being chipped, so I wonder if it is something in the Amazon fulfillment that causes the damage, as these come straight from the factory.
The picture is very deceiving. All the parts look like they are pretty good quality, but even the silver posts at the end of the bed are painted wood. The side rails came predrilled in the wrong places, which makes it IMPOSSIBLE to securely connect the rest of the bed to the headboard. Whenever i tried to move the bed even an inch, the entire thing would fall apart. Not only that...most of the slats were chipped, and just making the bed would chip it even more.
Shipping was on time and the final product is beautiful.. however, there were many chips and cracks in the wood planks (that we ended up disguising and covering up, and the instructions are TERRIBLE. It gave my partner and I an aneurysm trying to interpret the instructions!
The packaging seemed absolutely perfect in size and level of protection, but (as with other reviewers) once I opened everything there were small amounts of damage to the various pieces. Once I had everything assembled and the bed made none of the damage was visible.It took about 2 hours to completely put everything together, including getting the mattress and sheets on, but I didn't have as much trouble with the assembly as what I read prior to making the purchase.
Answer: No! I have a really thick memory foam mattress on mine and it fits perfectly. No box spring needed!
