    • The quality is unparalleled!!!
Size: Split King Style: 14" Med Soft + Harmony Base
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!!! ... show more

    • So comfortable and great price!
Size: Split King Style: 14" Med Soft + Harmony Base
Review Image by Jordan Loscar
I was skeptical, buying a bed online without trying it. But I decided to try this bed out and boy has it lived up to my expectations. This bed is well worth its money. I was between this one and the platinum edition, but could not figure out what was the difference between the two was. So to make it easy for others the platinum edition has an adjustable lumbar support and the classic doesn’t. That wasn’t something I needed for the additional money. I highly recommend this bed and I appreciate all the prior comments regarding this bed that made buying this bed an easier decision. Things to keep in mind the massaging function works, but not as strong as I would’ve expected. Also if you get the king split, I recommend getting a bed bridge. This is necessary due to the gap between the two mattresses. I ordered that on Amazon as well. You can’t beat the deal on this bed for its quality. Installation is incredibly easy and I was able to do it by myself. ... show more

We have been sleeping on this for about 7 weeks now. We really have enjoyed this bed. We have had some adjustment to the split King setup and I am not totally sold on the crease in the center. That is not a problem with the manufacturing or the bed itself but with the style in general. We have put it through its paces and really like all of the settings. The remotes came already paired with their individual side of the bed but there is a sync button inline with the power cable in the event that it needed it. The three different vibration levels are sufficient for just a light amount up to a real good rumble and is nice after a long day sometimes. The under the bed lighting is very nice and puts out plenty of light to see where you are going without disturbing the other person. My local delivery company wasn't very flexible with delivery and my wife had a last minute trip out of town so I had asked about delivery the following week but they would only allow 72 hours on their dock before automatically returning the bed. I opted to take a day off of work to receive the shipment. The driver was supposed to drop at the curb but since the driveway is paved and flat he just rolled it straight into the garage for us. The assembly consists of adding the legs to the bottom of the bed, adding the mattress retention stop at the foot, and plugging it in. Be prepared by having 9v batteries on hand (2 for each side), I wasn't sure what they were for since the bed is plugged in but guessing it may be power to lower the bed if their was a power outage so it isn't stuck in some position other than level. The bed came on a pallet with the two mattresses on top all strapped together. The unboxing was extremely easy by opening as a clam shell and simply removing the bed and folding it out. There were two boxes inside that had the parts and the remote controls, with the owners manual. This fit directly into our existing bed frame with the cross supports removed. I will say that we have a pretty high foot board that is flush with the mattresses so making the top sheet up with the retention elements and foot board in the way is a bit difficult. Getting the fitted sheets over the center top corner of each mattress is also a bit difficult but not a problem unless you have mobility issues. On night 2 the cross member that lifts the upper half of the bed separated due to a bad weld. Two pops and it was done. I believe that the first weld failed passing the all of the load to the other side causing that side to fail. I got out of bed and wrote to them immediately late that evening. I was contacted first thing in the morning. They were very apologetic but I understood that sometimes there are bad welds since I have worked in manufacturing before for many years. They had me send pictures and the serial number and processed a replacement shipment for that half immediately. They also had the white glove delivery and installation at no cost to me. They came in and packed up the broken unit and put the new one in and tested it and made sure I was satisfied before leaving. I couldn't have asked for a better response from the seller or the white glove service people. As you can see by my star rating we very much like the bed and would recommend this. We may eventually go to a solid king versus the split just to get rid of the seem in the middle. It is possible to sync the two units for using a non-split mattress. ... show more

When I tell you this was my dream bed it was. I loved this bed so much. And it pains me that I had to leave it once my ex and I split. It would have cost a lot to travel it 6 hours away. I’m a travel nurse and it helped my pain so much. When I say I love this bed more than my ex, that’s saying a lot. Everything worked like a dream. The mattress was perfect med soft. The controls helped my inflammation and swelling on hard shifts doing bedside nursing. My dream is to get this bed back again. And it will be the first thing I purchase again once I’m don’t travel nursing next year. ... show more

Well built easy assembly, lighting is a bonus, good value. Only thing I would have changed I changed mattress from med soft to a more firm model. I am not dissatisfied with the mattress but have been to a firm mattress. I am adjusting well to the one that came with the bed. I set the bed assembly on my existing storage bed base. ... show more

    • SO Comfortable! Should have bought this a LOT sooner!
Size: Split King Style: 14" Med Soft + Harmony Base
We bought this bed to help alleviate my husband's health issues, but it also happens to be the most comfortable bed we've ever slept on! We initially put off the purchase over concerns about the size & weight of it (handling it & getting it into the house) and whether or not we could afford it. We found out that the pallet consists of 4 separate boxes, which made it manageable to handle for 2 people, and Amazon offered an interest free payment plan which made it doable. We now wish we hadn't put it off! There's a variety of positions to choose from & the ability to fine tune them, using the remote (which lights up as you push the buttons) --also wonderful for reading & TV viewing. There are vibration settings, a flashlight button & an under-bed nightlight for finding your way around the room without waking your partner. The remote is essential, so we ordered 2 sets. I bought bags (made for a walker) to keep them handy, along with the TV remote, bottle of water, etc., & attached each to a 10" safety grab bar, which slides under the mattress (to the side or above the head) without interfering with the mechanics of the bed. The safety bar is easy to assemble, DHA! (Dubious Husband Approved). I also like having it to grab hold of to help get in and out of bed. https://www.amazon.com/dp/B01LEG5ZAI?psc=1&ref=ppx_yo2_dt_b_product_details https://www.amazon.com/dp/B0836DFY1J?psc=1&ref=ppx_yo2_dt_b_product_details My husband and I put the bed together ourselves without much difficulty. We attached the leg extensions that came with the bed, and I like the room under the bed they create. However, I recommend trying it out with the mattress before you add the extensions. I'm 5'9 and have to flatten the mattress setting to get in and out of bed comfortably. My 6' husband likes the height. This bed is a major purchase for us, but one we are very happy with -- overall a very good experience! ... show more

We've had the adjustable king bed for 4 1/2 years and my husband and I love the bed! Everything still works. I did add a mattress topper for extra comfort but I've never had a mattress I haven't had to add a topper to. Wonderful bed, I would definitely buy one again!
