Set up was so easy I didn’t have time for pictures
This has to be one of the most sturdiest adjustable bed frames I have ever had. Right now I have a total of four different adjustable bed frames in my house and this one is by far the best. I definitely feel that you get a high-quality for a fair price. The base is quite heavy, so I do recommend having at least a spare set of hands to help you unboxed and set up. The actual set up is very straightforward and very simple. It’s almost a plug-in play style. I’m also a huge fan of the interchangeable height for the bed. But I’m even more of a fan of the fact that you can get a full foot of height, without sacrificing rockiness of poor quality legs like I have on other brands. I do find the massage function a little less and some other brands but it’s not a dealbreaker. I mean for me the best selling feature was the adjustable neck position. The only other thing that could’ve came with would’ve been a lumbar support. Which I know they make for queen and king size beds. I just wish they had it for a full or twin.

Great Purchase
I wanted to have and use this bed for a few months before writing a review. I have had it since February and I love it. It is very sturdy and all the controls work perfectly. I have it placed on a platform bed frame and have had no issues. Know that if you choose to put this on a platform bed, you will have to move your nightstands forward to be able use them once the head is raised. This is reportedly not the case if you use a traditional frame and the provided legs. I also suggest that you use something under the platform to help with the weight, (I have the king bed), I used four heavy duty milk crates, one in each corner, to help carry the weight. Again, this bed is very heavy. That said if you plan to set this up yourself, you need to have a clear cut plan, or in place of that, a few friends to help. I paid to have the bed put into my garage so that I could work out a plan of attack. The bed frame itself is mostly completely assembled but I knew there was only the two of us, (two women), who would be setting this up the rest of the way, although it took us about an hour including a few breaks to strategize, we got it moved into the house and setup without injury. I am overall completely happy with my purchase, this bed has helped me sleep comfortably and as a result much longer than before. Hopefully it will continue to work as flawlessly as it does now, and I will get a lot of years of use out it.

Wow!
This is our first adjustable bed. We watch TV in bed before retiring and this is the most comfort we have ever enjoyed, in or out of bed. We decided to order 10” mattresses from a big box store since my wife requires a firm mattress as a stomach sleeper and I enjoy a medium as a side sleeper. The setup was easy in our first floor master. Even though we are seniors, using leverage carefully while moving, and a hand truck that has four wheels, like a cart, we were able to move, unbox, install legs and flip without a problem. From a users perspective, we like the lighted remote, the head adjustment and massage, and surprisingly, the under bed lighting which helps to maneuver around the bedroom at night. As an engineer, I really like the thoughtful design, construction and apparent quality of this product. The only negative was the notification by the delivery driver. He called at 8am and said he’d be at the house in ten minutes while I was out. He did drag the boxes up four steps to the covered porch and out of the rain however.

Three part HONEST review.......Read it all please.
My first review was 'squashed' by the Amazon overlords because I was apparently overtly rude. Oops, my bad. When you read this 'entire' review you'll know why I was so angry. So, here goes the second attempt! This review will break down in the following 3 TRUE AND FACTUAL categories - 1. Order/Delivery (including my research) 2. Customer Service 3. The actual Product. If Amazon strikes me down for telling the truth about the ENTIRE PROCESS OF ORDERING, RECEIVING AND USING THIS PRODUCT then they apparently only want warm and fussy less than honest facts. Preface - My wife and I are cautious buyers so we do our research before buying - especially on high priced products. I did a significant amount of reading online and YouTube testimonials when searching for a mattress and bed frame to replace the miserable mattress that was eating our backs alive! I decided on the Layla non-hybrid mattress that offered both a firm -and- less firm side. Thus, we had two shots at a comfortable mattress; smartest move ever. The Layla was PERFECT especially for side sleepers. And I decided I wanted the Sven & Son adjustable frame for it's quality reviews. I opted out of the Sven & Son mattress because I just could not get a sense of what was firm, medium or soft because that is so objective. If you read comments on the mattresses you'll understand what I mean, that said, reviewers universally liked the power bed frame. Decision made. 1. Order/Delivery If you check out both Amazon and the Sven & Son sites regarding their products you will find that if you order 'direct' through Sven & Son you pay a bit more but work 'directly' with Sven & Son themselves. But, if you order thru Amazon you have a middle mad, if you will, that is Sleep Geeks and all returns or warranty issues go through Sleep Geeks. That gave me some pause, but I decided to order directly through Amazon for the price advantage and because Sleep Geeks had several favorable comments from buyers...you'll find I do too! After hitting 'order' on Amazon my next communications were with Sleep Geeks. Every single email and call I had with Sleep Geeks from the first to last was VERY PROFESSIONAL and polite! I even reached them on 3 consecutive Saturdays! Wait, what? Why did you reach them on three consecutive Saturdays? Why, because the INEPT shipping service failed to deliver the adjustable beds - not once, not twice, not three times, but FOUR TIMES! Technically they delivered on the fourth delivery date....30 minutes late...and one box was damaged! Throughout the annoying process NO HUMAN from the shipping company EVER CALLED ME in person to ask when I wanted the items delivered. Instead, I received text messages stating I'd get another text the night prior giving me a 4 hour window. Needless to say Sleep Geeks felt my frustration on every single call and they also did everything possible to find a solution asap. If I note the name of the shipping company Amazon will probably squash this review - again. End result of all that is, given the positive product review I'm about to give, I would order this product but I would have conversations with Sleep Geeks regarding your desire to speak to humans that give 'you' the choice of day and date delivery!...and that they show up. 2. Customer Service Sleep Geeks provides EXCELLENT CUSTOMER SERVICE! Answered phones promptly, always polite, professional even given my utter frustration and anger over missed deliveries. They answered all my questions and immediately, never gave me the run around, and addressed all my concerns as promptly as possible. Trust - Sleep Geeks are good people - have no fear. 3. Product As I noted one of the boxes was damaged so I almost returned the order, but Sleep Geeks assured me that I could note 'damaged' on shippers receipt and Sleep Geeks would repair or replace if there were any issues. I'm glad I just kept the order. The product is heavy, 2 men could carry in house easily, but since it was just my wife and I we simply and slowly 'square wheel' rolled it from garage to bedroom, no worries. We pulled the beds out of the box, followed the simple instructions, do that and the bed will be in place in just a couple minutes! Save yourself time, use the bed leg extenders, you'll need them to achieve a standard bed height. Note we're nearing 60, if your older you might want to consider grandsons or the white glove set up service. The bed is AWESOME (so far) our version is the twin XL with head tilt, message and under bed lights and USB ports. Hands down the BEST mattress / bed scenario we've EVER had! The message has multiple settings for multiple body locations and is GREAT! It does auto of after like 10 minutes but I think that's a good thing. The bed frame is sturdy, firm, no wobbling, the electronics seem quality. Zero Gravity is great and my wife can finally sit up and read without one of those nasty back pillow things. We have found that sleeping flat is not desirable with this bed, we actually raise the head of bed a touch as well as feet. You'll find the right combo for your need. As side sleepers the 'hip pointers' ache every morning is gone! One note on electronics, the bed does require two 9 volt batteries (4 for the 2 twin XL frames), given the price I thought those could be included; luckily I had 4. Please note the battery compartment is pretty tight so you'll have to noodle the wires a bit to get the thing to close. Also, the remotes do light up in dark if you tap a button, it just doesn't stay illuminated long enough to find the button you want. SO......Would I buy these adjustable again, Yes. Do I think this is a quality product, it seems to be so far. Does the 5 year+ warranty offer another reason to by this bed frame, it seems to so far. Would I suggest that 'you' buy this product, absolutely! Noting of course my concerns within the review. Would I want the same shipping company, uh NO!!! I left a lot of my anger regarding shipping company and their miserable customer service and tried to base my review on the entire process from researching a choice to receiving and using the product I chose. I spent a hot minute reworking this review...I'd appreciate if it be posted. Thanks.

Well worth the money surpassed my expectations !!!!!!!
It arrived by freight carrier and its crazy heavy like 241 pounds so I suggest getting a few young muscle bound bulky men to move it. Cause it's a monster very well built I was impressed. Me and a friend moved it and it's quite a job. Assembly was simple and easy it works great, I paired it with a 15 inch serta mattress and the massage feature actually works better than I would of thought, the zero gravity is nice also I use it when watching TV. In all I am completely impressed for the money. I would highly suggest this adjustable base if you are in the market for one. and a couple muscle men to move it. LOL.......

Love my new adjustable frame!
This was delivered a week ahead of time which was great. The set up was nothing, just screwed in the feet and plugged it in. Seems to work great and fit in my 4 poster frame perfectly. I loved the fact that you could place the feet in wide socket or narrow socket. Also had the choice of 6, 9, or 12 inch legs. Motors are quiet and movement is smooth. The massage feature is not overbearing just a nice minimal relaxing vibration. The zero gravity setting is the best. My only suggestion is to have two men available for set up as even the twin Xl was quite heavy. We did it with two women and a man but it wasn’t easy attempting to lift high enough to place inside the king frame. I might pick white glove service next time. Great product so far. I love it!

Works mechanically. Causes horrible back pain
Not saying the product is bad as it does what it says and moves like it says. It's very easy to put together for full size just screw on the legs. The bottom cap for the legs ate alittle hard to get on. My problem with this product is my back problems are so much worse with this. No matter the angle I try I get severe back pain. I bought this because of my back problems. It's been days since I've been using it and have not been able to adjust to it yet. I'm hoping I can adjust but I'm not hopeful. It may help for some people but my experience is it has not helped and made my back worse off so beware when you buy that it may not solve your back problems.
