  • Quality, Value, & Customer Service!!
Size: Split King Style: Adjustable Base Only
Purchased a pair of twin XL/Split King adjustable beds, box says Flexispot model number S6TXL-V2. Customer Service was excellent and attentive. I had questions, contacted the seller and received complete answers/resolutions within 15 hours. They also followed up, encouraging me to reach out with any other questions or concerns. They were very helpful and I would buy from these folks again. I am a 62yo female with a disabled spouse who is recovering from a joint replacement. I was able to unpack these boxes on my porch where FedEx delivered them and bring the pieces inside, by myself, one section at a time. There are 3 sturdy painted steel sections to each bed. All electronics and motors are securely attached to the frames, and further secured for shipping with zip-ties. I assembled them alone, using a vice grip to hold the sections together while I screwed in the 4 screw-in connectors on each bed. It worked great! I did not install the legs that came with the beds as I have mine mounted on a solid platform base that my husband made for us years ago. To ensure they wouldn’t slide around on the platform, I used contact cement to attach some rubbery shelf liner pads where the legs would have screwed in. Additionally, I screwed a couple of small lag bolts into my wooden platform base at the head and foot of each of the adjustable bedframes and 2 on each of the outer sides. I didn’t have to screw into the metal frames, just along the outside edges to isolate any sliding motion of the frames on my solid base, since I didn’t use the legs provided. It was super easy to do. If I weren't too lazy to get the chop saw out, I’d have screwed wooden furring strips down beside the frame instead - but simple lags worked to hold the frame in place. I put mattresses on the bed-frames first to make sure the bed-frames were spaced properly before putting the lag screws in. These beds were super easy to assemble. Slide together - screw in 4 plastic capped screws. Attach the color coded wires. I had my husband steady each frame from the foot of the bed as I flipped them right side up myself. This part would have required 2 people if I had used the legs. I even drilled a dime-sized hole near the center of each of my wooden platform bases, disconnected the underbed lighting from the flexispot frame (2 screws for each light) and pushed the lights thru the hole that I drilled, so that we have the under bed lighting feature under our wooden platform bed. The beds work great. WE LOVE THEM! It was a great purchase and I feel, an excellent value. The little pockets they provide at the side of each bed for the remote are only large enough to hold one remote sideways - but I’m going to have a friend make us a couple of new, deeper pocket holders that will hold the bed remotes longways as well as our TV remotes and maybe even our reading glasses - it’ll be a buffet of bedtime accessories. The remote control includes 3 buttons for making your own positional presets (just press and hold until the lights flash to get the remote to memorize a position). There is a zero gravity setting, and a single button push to make the bed return to flat. The massage feature allows you to select feet only or head only or both, and there are 3 time presets for that. Plus you can press OFF to stop it instantly. The massage noise is going to depend on the surface your bed sits on. Mine sits on a solid wood platform base over LVP flooring in a room built over a basement (not on a solid slab) and the massage wasn’t silent, but also wasn’t too bothersome. I expected it to be loud in this environment. But! could have it on and watch TV with no problem. Oh! and the remotes also include a LED flashlight feature from the end of the remote itself, as well as controls for the underbed lighting feature. The remotes also have backlighting for all of the buttons - very handy!! I’d make this purchase from Flexispot again. I really can’t find anything negative about them. ... show more

  • Worth every penny.
Size: Split King Style: Adjustable Base Only
After researching many brands of adjustable beds, some very expensive, and some not so much. We chose the Flexispot based on reviews and the price. This was a very good investment. The bed frame was packed very well and arrived unmolested. Be prepared for the weight of the packages upon delivery as the boxes are 102 pounds apiece. Assembly was a breeze, only four thumbscrews per side and plugging in a few color coded wires. We literally had the bedframe put together and operable within an hour. It's amazing how good an adjustable bed can improve nightly sleep. I would put the Flexispot up against any of the higher end and much more expensive brands. ... show more

  • I shopped hard, and this won by a mile. A fantastic unit at a great price!
I was at a home show, and a mattress vendor had a motion bed in their booth. I knew about hospital beds, but this was different. And it was extremely comfortable! But their "system" wouldn't work with my existing bedframe, which has storage drawers underneath and a foam "bed in a box" mattress. I started shopping for something that would fit between my mattress and the slats in my bedframe, and found several products over a huge price range with a wide variety of reviews. I picked this one because it seemed to have a good balance between price and reviews, with a good number of sales. It was awkward to unbox and place in my bed, but I was doing it alone. It would have been MUCH easier with two people! Please, do this with a friend! First test was weird. My mattress stayed flat as a board and was lifted up with the mechanism! I got in the bed, and the middle of the mattress stayed low, where it belonged. But the foot of the mattress still lifted up. Clearly, my extra-firm mattress was NOT designed for use with a motion layer! I recommend getting a mattress that specifically says it is compatible/recommended for use with a motion system. I fixed my problem by taking a pair of 1" nylon cargo straps and wrapping one around each corner of the foot of the mattress, which totally solved the problem. But I do plan to get a new mattress sooner rather than later. With that issue sorted, it was time to make the bed and put it through its paces. I really love that I can program in 4 of my favorite positions. I have one for reading in bed, and another for when I have some nasal congestion (allergies). I could have gotten a motion layer with or without massage vibrators, and I really didn't care either way, as I doubt I'd ever use them. While I selected this motion layer for other reasons, I'm now really glad it included the vibrators, but for a totally unexpected reason: It helps my brain turn off when I'm having trouble falling asleep! I think part of it is the low humming noise, which blocks other sounds, particularly from nearby traffic outside. And I think the vibration also helps me avoid becoming physically uncomfortable, which often happens when I'm awake in bed, much like how rubbing a child's boo-boo can help make the pain disappear. That said, the "massager" does nothing for my muscles, such as when I go to bed aching after a late workout or a hard run. But it's nearly a miracle for what it does do for me! I was a little worried that such a thin layer (under 4 inches) could be truly strong. That worry was put to rest when I did a gravity hip flexor stretch on the foot of the bed, basically raising the foot to maximum height, sitting with my butt halfway past the foot of the mattress, then laying back while dangling my legs over the edge. The mechanism didn't care one bit. Piece of cake! This is one awesome piece of hardware, with great controls and features. Highly recommended! ... show more
