Bought 8, 2 are somewhat broken but still usable after 6 months use. They are as advertised and arrived on time.

I don't think I needed to raise my bed a whole five inches.

The height didn't allow for me to stack those under the bed bins so I'm not sure what the point was.

They were sturdy and I was never worried about my bed falling.

Once I moved into a new place, my ceiling wasn't as tall so I downgraded to a set of 3 in risers which were perfect. Actually, 2 inches would have been perfect but I couldn't find those.

Just the right height to get out of tall bed with extra foam topper

Denim look, not as vibrant as pic... but lovely just the same. We put risers under the main bed and used two 8 inch mattresses

I did not use these on a bed. Instead I used them to raise my cutting table. I quilt and the table I bought at a big box store was too low. I used the 5" risers and now the table is PERFECT!.

It was just the right thickness to add some needed height to a platform bed with an 8" mattress.  At first, I thought 5" would be too thick, but it worked perfectly.  A Bunkie board would have been far too thin.

The bed is nice and high. I slept on it with my 4 year old and it was semi-comfortable. I am 5"4 and weigh 135 and it held both of us just fine. Didn't seem to lose any air overnight and was fairly easy to assemble and disassemble. It would probably be more comfy with a mattress topper of some sort. Deep pocket sheets are a must.

The bed seems ok, all thought we have not slept on it as of yet.  We just blew it up and it seemed to be holding the air without going soft.  Will know more after we use it....

these do the trick for elevating the whole head of the bed which my doctor wanted me to do to alleviate acid reflux symptoms. I think do sleep better by using them. I think the recommended 6" would have been too much elevation for me. I don't have a headboard because my queen size bed takes up pretty much the whole room. It looks steeper than it feels. I won't say i love them because who really wants to do this?) and i'd rather have the bed flat. So far i have had no problem with them or with sliding down in the bed, so yes it was a good purchase for my needs

Bed risers. They worked fine. The bases are large (for stability). There are four pairs of risers (3 and 5 inch). They are very sturdy, with a 3" x 3" recessed square to hold the legs of the bed.
You could use this kit to raise two separate beds (one 3" and one 5"), or combine them for up to 8" of extra height.

This is a fantastic headboard, and especially for the price.  It really completes the look of the guest room.  It looks well-made.  I bought the twin size.  I consider my mattress and box spring to be fairly high (27" to the top of the mattress).  The top of the headboard is 45".  I'm attaching a picture, but it doesn't do it justice.  There are two different settings for height (when you attach the legs to the headboard) so I'm wondering if the people who complained that it is too short didn't realize this?  Also, it attached just fine to my ~10 year-old standard metal frame.

Wanted to raise my 24" monitor up off desk.  This sturdy metal stand raised it up 4.75".  Nice drawer to put stuff in and off desk.  Highly recommend

I'm not sure if they are using miniature beds in these graphics, but the product is less than three feet wide at its widest point.  The graphics make it look much bigger than it really is.

Love the quality and style of this set.  Bed is low to the ground and actually needs a box spring in order for the mattress to meet up with the headboard.  I used risers so I was also able to insert a 6" mattress trundle underneath bed.

It's everything advertised and more and so for that I give it 5 stars! ... except I didn't realize just how high my bed would be. After getting it I think I could use 2-3 inches off. It's not the easiest bed for me to get into and I worry about my dog jumping up and down. He's 3 now, but eventually this won't work. Also my husband who is only 42 (who thinks you have to worry about these things now (I'm 30?) recently had a stroke and our bed height has also made it challenging. So if I read this review 3 months ago I would have said "not me, and I need to maximize space." For most people, this bed frame is all that and a bag of chips... and I wish I had gotten something more around the 14-15 inch range or gotten a bed that raises with storage underneath like the ones from ikea. There are so many other ways to maximize space.

My last bed risers raised the bed 5 inches. I wanted 2 more inches of space, so I bought these. They appear to be solid. I am hoping they hold up.

They are quite large, but perhaps have to be that large to be solid and strong to hold up the bed.

I bought the extra long because I have the bed on risers and wanted to be sure the end of the bed was covered by the bed skirt. The color is as pictured and it serves the purpose.
