  • Excellent choice. Exactly as described.
Size: Queen Style: S3_Zero Clearance
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. ... show more

  • Functions perfectly, sturdy, comfortable.
Size: Twin XL Style: S3_Zero Clearance
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. ... show more

  • Easiest set up ever! Total control over adjustments! Awesome!
Size: Queen Style: S3_Zero Clearance
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! ... show more

  • Great seller and great product
Size: Split King Style: S3_Zero Clearance
I purchased these almost a year ago. I wanted to make sure it wouldn’t fall apart within months. These are actually two separate pieces - which I love. Incredibly easy and fast to set up. Mine worked great out the gate. My husbands worked at first and then became unresponsive. We contacted the customer care folks and they walked us through some trouble shooting. It didn’t work. They decided to send us a new remote, asking us to please send the old one back to them once we switched them out. The new remote arrived and they helped us with the set up again. I sent back the new remote. Both frames have been working perfectly since. Customer care was fantastic: responsive, good follow through, didn’t give up and took responsibility to make sure we got a solid functioning product. When my boys get settled I’ll definitely purchase this product from this seller again. Without hesitation. ... show more

  • Quality, and great customer service.
Size: Queen Style: S3_Zero Clearance
Extremely well made, and love the lights on the bottom they are awesome, well packaged and a company that I found to stand behind their products 110% when I did have an issue. I plan on buying another one, Oh yeah fast shipping, I love it.

  • Easy to assemble - well built!
Size: Twin XL Style: S3_Zero Clearance
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! ... show more
