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.

First I want to say ,get help the bases are very ,very heavy and hard to leverage when setting up inside your base if you got a split king like I did!!! With that said after setting up by myself, removal and all I had the best nite sleep I had in a long long time!!! Years!!!!The base motors are basically silent and operate flawlessly,the zero G mode is my favorite position on the remote!!! These mattresses are very well made and the comfort level is perfect for me and my wife!!! We both are in our 50s and our lower backs are sub-par at this time,we'll obviously it was the previous bed that was truly hurting us!!! Ergonomics is everything !!! Stay away from the so call mattress warehouses,those guys are worst than car sales men!!!! Sven & Sons quality is fantastic,worth every penny!!!

I thought long and hard over getting this. I have back and leg pain so sleeping has became more and more difficult. I ended up sleeping in a chair a lot of evenings. I looked at a lot of store bands and just could not afford $4-8K that the top brands cost. This Sven and Son actually offered more features and it was at a price point that I could afford. So I gave it a shot. I got the split king because my settings are not anything close to what my wife would want. I worried about the gap and it doesn't seem to be an issue. In fact we wake each other up a lot less now. You can still get close. We were actually sent the model up from what we ordered, I didn't order the lumbar feature but it came with it, which also means it came with the app support. So that was a $200 gift (thank you). Having the extra features are nice and I like them more than I thought I would so I'm glad I got them. A couple of comments that made me cautious about purchasing this brand. One was about the loudness of the motors. One comment said they were as loud as a forklift, they are not! Now that I have them, I can say they are not silent, but they are not too loud. I raise and lower the bed in the middle of the night and the motors do not wake up my wife. (this of course is very subjective) They other thing was the softness/firmness of the mattress. They are listed as med-soft and I would say they are mid-firm. I was happy with this but my wife wishes they were more to the softer side. But they feel like very well made mattresses. We are extremely happy with the purchase. The delivery was super fast. I didn't get the white glove because I had help available to bring them in and set them up. The setup is super easy and fast. For people that get the models that have the mobile app remotes, there are no instructions on setting up the app. But you have to scan the code on the back of the remotes in the app that links them. You get all the controls. I'm going to like this because I lose remotes a lot more than my phone.

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.
