So glad I chose this adjustable bed base. Very heavy, well made, very easy to put together, durable upholstery, has two motors as shown and that is one reason I chose it, the one for the head is already connected and we connected the foot motor easily. Works perfectly, presets are very helpful and response is quick and smooth. Great stability, sturdy, great product and great price. Made a great bed with my Sweet Night 14" mattress. Highly recommend and would definitely buy again. The adjustable legs are perfect and it fits inside my existing Cabana Banana Leaf Bed.

Having two Flexi-Spot adjustable desks that work like dreams, I felt confident in buying a Flexi-Spot adjustable bed frame. This product is fantastic. Shipping box and packing is super sturdy. The customer assembly involves carrying folded product to location, attaching two bolts, several zip ties, plugging in two cables, plugging the power cord in to the power brick and flipping the whole unit over on to the existing bed frame. We spent more time vacuuming under the bed then we did assembling. The remote is simple and easy to use. Unwrapping the batteries from the shrink wrap was the hardest part of the install, LOL! The bed racks…they keep the mattress from sliding…just get pressed in. It’s easy to locate the foot the bed when assembling because there are two holes on the top for the bottom bed rack. They are unobtrusive and end well below the mattress. We have a latex mattress that isn’t deep and the racks are not a problem. We did move one wooden slat from the existing bed frame under the top cross beam of the adjustable frame away from the movement arm. The arm doesn’t hit the wooden slat would flex down and make a bit of a tapping sound. By repositioning the wooden slat the problem was solved. The best part is RIDING this newly crafted bed/amusement park ride! Jump on and start playing with that remote. Lay flat and hit the zero g button. The bed movement is silky smooth. The motor is quiet and when the foot end is moving it’s almost silent. Super fun to push all the button, try out different heights, trying out laying on back, on sides, with feet up, with feet down, laying there and letting the frame raise to “reading” height, try every combo you can think of. Post sleep result: this frame is magical!

We bought these to make our king size air bed into an adjustable. Using our two twin XL mattresses we we able to transform our bed at a fraction of the cost of a name brand adjustable air bed. We love how heavy & durable these frames are, and they do all the same positions & have most of the same features as the expensive name brand. They were pretty simple to assemble, just a bit time consuming. I think it took us about 2 hrs or so to put both together. They are sturdy & operate completely silently. We are very pleased with these. The company builds quality products.

I've been using this now for about a week. The item arrived before it was scheduled, which was a nice surprise. Although the shipping company damaged the box, the contents seemed to be fine. I am a 5'4" 125 lb female and I put this base together myself. The material is thick and durable. The parts were clearly labeled to assist with construction. A unique thing I really like about this base is that it comes with TWO metal mattress stoppers which hold the mattress in place when it's in motion. I only saw one on the other models I shopped. I am not having to push my mattress back to the center as a result. The motors (2) operate very very quietly. There is no clanking or unusual sounds to be annoyed by. This comes with a 5 year warranty. I purposely ordered this because I didn't want to pay a bunch of extra money for a "massage" function which actually only vibrates the bed.ir was important to me to have the zero gravity position on the remote and this does. There is a helpful button on the remote which lights up the options to change position in low lighting. I use it regularly. The hardware even came with felt already attached for improved operation without extra noise. There is one suggestion that could improve this base and that is to offer adjustable legs. This comes with one size only and because my mattress is so tall, I cut these legs down to customize my needs. The legs did cut well but I have access to a band saw to do it. I am happy with my purchase and think you would be as well. I do not often review items but I think this company goes the extra mile to offer a very quality product for a very fair price.

This is my first adaptable frame so I have no point of comparison. But set up was not bad and it feels sturdy and works and I have no complaints. One thing to keep in mind: the product arrives in a box that is very heavy. It says on the box that the product should only be lifted with machinery. Fedex deposited it at the bottom of the steps to my home and it was an exercise in strategic maneuvering to get it up the steps and into the house by myself. I was home at the time and saw the Fedex lady wrestling it out the back of the truck (I'm pretty sure she just pushed it out and let it drop to the floor). I asked is she needed help, and she pointed at it at the foot of the steps in the rain and said: "Nope, it's all yours" and drove off. The product was undamaged -- I guess it is sturdy and well-packaged. Just keep in mind that you will likely need someone to help you bring it in.

This bed was 95% pre-assembled, it took me less then 5 minutes to completely set up. It is heavy, but very sturdy. I would recommend two people at least but somehow I managed on my own. All of the components are very strong and sturdy, and are finished nicely everywhere. The bed operates flawlessly and very quietly. The retainer bars keep my mattress from sliding around. Easy to use remote to adjust head and leg positions. I definitely recommend this adjustable bed!
