Osaki OS-4000LS

2D L-Track

Enjoy complete relaxation as the Osaki OS-4000LS massage chair’s 42 inch roller track massages your neck, back and buttocks. The OS-4000LS is equipped with dual mechanical foot rollers, 6 auto programs, 24 airbags that compress against your body, low back heating, body scanning technology, space saving recline, a shoulder adjustment, an extendable footrest, and more.

42" L-Track Massage

The Osaki OS-4000LS massage chair is equipped with a 42″ L-Track design. The quad roller system massages your neck, entire back, and trails underneath the seat to reach your buttocks.

Foot Rollers & Leg Airbags

Dual mechanical rollers target your feet’s acupoints and therapeutically knead the bottoms of your feet. While this is occurring, airbags inflate against the sides of your feet to create a squeezing-like motion.

Airbags also squeeze your calves, delivering a rejuvenating leg massage.

Zero Gravity

The Zero Gravity recline position perfected by NASA places your legs level with your heart and evenly distributes your weight across the chair. This “weightless” recline relaxes your neck and back, increases circulation and blood oxygen levels, expands lung capacity, and reduces tension throughout your entire body.

24 Airbags

Due to the extended 42″ roller system massaging a larger area of the body, the Osaki OS-4000LS requires fewer airbags. Its 24 airbag count is plenty and still targets the key regions of your body.

The airbags compress against the shoulders, arms & hands, lower back, waist, calves, and feet. The airbag strength can be adjusted by pressing the “Intensity” button on the remote. The OS-4000LS offers five airbag intensity levels — from mild to strong.

Lumbar Heat

Two heating modules are located in the lumbar region to help soothe away muscle tension. Heat therapy loosens up your back’s muscle fibers and allows the rollers to penetrate deeper into your spine.

Adjustable Shoulder Width

The Osaki OS-4000LS is one of the few massage chairs featuring an outer shoulder adjustment to accommodate users of various builds. Most chairs typically have one stationary position which can often neglect users who have broader or narrower shoulders. To adjust the shoulder position, firmly press the shoulder panel inward or outward up to 3 different widths.

Body Scanning

The Osaki OS-4000LS features the latest in body scanning technology. When powered on, the chair maps your back, detects your body’s acupressure points, and customizes the massage rollers for your unique body shape.

6 Auto Programs

The Osaki OS-4000LS is equipped with six touch-and-go automated modes targeting the entire body.

Read Auto Program Descriptions

Deep Tissue: This auto program engages the full body in a deep tissue massage. It focuses on the neck, shoulders, waist, and hips.
Stretch: This auto program fully stretches the body, including the back muscles, hands, hamstrings, and waist.
Energy: This auto program delivers a light, stimulating tapping massage throughout the entire body.
Relax: This auto program starts with a slow kneading and heavy tapping massage, which progresses into an in-depth neck and lower back massage.
Full Air: This auto program takes advantage of the chair’s airbag technology. It applies a full body air compression massage to the shoulders, arms & hands, low back, waist, thighs, calves, and feet.
Manual Air: This auto program turns on the specific airbags you want to activate.

Custom Roller Techniques

With the Osaki OS-4000LS, you can dive into the remote control’s manual mode to pinpoint specific areas of the back you want the rollers to target. For example, if you have an aching neck, you can localize the massage to that particular area and choose from one of four distinctive roller techniques (Kneading, Tapping, Shiatsu, and Rolling).

You can also set the width of the rollers (three levels of adjustment; from wide to narrow) and speed of the rollers (three levels).

Vibration Massage

The Osaki OS-4000LS has two plates embedded inside the seat which can be activated to enjoy a soothing vibration massage.

Space Saving Recline

The Osaki OS-4000LS slides slightly forward as it reclines, allowing the chair to be safely placed within 4 inches of a wall. This is a great feature for those who have limited space and/or want a chair with a smaller footprint.

Extendable Footrest

The spring loaded footrest can accommodate users up to 6’4″ in height. To extend the footrest, simply push outward with your legs.

4000CS vs 4000LS

The OS-4000CS and OS-4000LS are both the same chair with the exception of one important feature: foot rollers. The OS-4000LS includes rejuvenating foot rollers; the OS-4000CS features a less impressive, airbag foot sole squeeze.

Easy Assembly

The OS-4000LS ships in two boxes: the main body and footrest. The chair is already mostly pre-assembled. Simply connect the footrest to the main body of the chair and you’re ready to begin your relaxing massage.

Shipping Methods

Curbside Delivery

All massage chair orders qualify for free Curbside Delivery. Your order will be left on your curb or near your entryway after you accept delivery. The delivery driver will not bring your chair into your residence. Massage chairs are heavy and we recommend having another person or two on hand to help carry the box(es) inside. A dolly or hand truck can also be a helpful method of hauling the chair inside. Depending on the chair you are purchasing, your order may arrive unassembled. Assembly instructions are included in your chair's packaging and most models can be installed in under an hour. | Approximate Delivery: 1-2 weeks

Threshold Delivery - $75

The delivery driver will place your order at the first dry area available, such as inside a garage, near your entryway, inside a front door, or underneath a carport to ensure protection from the elements. This delivery method does not include room of choice delivery, assembly, unboxing, or debris removal. | Approximate Delivery: 2 weeks

In-Home Delivery & Set Up - $179

Your order is delivered directly to a third party agent. Shortly after the agent receives your order, they will call you to coordinate a delivery window. On that date, they will carry your massage chair box(es) inside the room of your choice (up to two flights of stairs), unbox, and assemble your chair. Note that in smaller markets, the third party agents are not necessarily experts in assembling massage chairs and we highly recommend opting for one of the other two shipping options if at all possible. | Approximate Delivery: 2-3 weeks

Please allow approximately 3-5 business days for orders to process and ship.

Best Chair EVER

I did a months worth of research. Other chairs were more expensive but did not offer the L track. That’s the tushie massage. My wife and have used this chair almost every single day 3,4 and even 5 times a day. I am on my feet all day and she sits at a desk. This chair is amazing. I was skeptical and worried because it was the most we have ever paid for a chair. This chair is AMAZING the feet massage is great. suggest wearing socks makes it perfect. improvements make the back light more visual so you can see it. got a light next to the chair problem solved. would like have it run for an hour straight. Puts me to sleep every time. Honestly cannot say enough good. Going to get a 2nd chair so we can both have our own. Wife and I joke constantly BEST CHAIR EVER. LOL more then paid for itself being that we would go to a get a massage costing 100.00 each time per person. Set up super easy it has wheels so you can lift it and move into place. It does take 2 people to move it to where you want then adjust is easy. live in southern California corona want to get one for my Midas shop.

Mr. SoLar

I am in love with Mr. SoLar! We meet twice a day for the best massage in the world. The way he plays music (Yoga) via Bluetooth is so relaxing. I’ve experienced most of the different massages and mostly use the Sleep and Auto massage. The Tai massage is out of this world. Mr. SoLar is out of this world. The Chair works great and is popular among friends and family. This chair is worth every penny. No regrets. I would definitely recommend this model and Massage Chair Deals.

I LOVE this chair. I had a different make and model for years and thought it was the best thing ever…boy was I wrong. The 4000LS has lot of bells and whistles. Mike suggested a more updated version because the color we ordered was not in stock and might not be for a long time…we opted to change the color and stay with the 4000LS. There are so many options to choose from… It is a good thing it comes with a detailed Instruction Manual. The Deep Tissue option was a little overwhelming the first time I tried it…but now it is my favorite. It is amazing how quickly it gets your body into relax mode. Yes it is almost expected to put you to sleep. The only thing I don’t like is that the On /Off power button is way in the back towards the floor. Since the chair is smaller and can fit into tighter spaces , it makes it difficult to each around the back and get down to the floor to turn it on and off. It has become the favorite piece of furniture in the house now.

We purchased the 4000cs and mike called us and said that they did not have any, so he offered us the 4000ls and I am so impressed with this chair. Every program and setting is amazing and I use it every day The foot massager is amazing also. Only negative issue is, my son is 6 foot 5 inches tall and can’t use it. Some day I hope you will develop a chair for tall and large people. We will be shopping for that also. Love the chair and your company. Great customer service.

I was going to order the 4000CS that Costco had on sale but after some researching I kept seeing other OSAKI 4000 series like the OS-4000 and this OS-4000LS. I was told by a rep named Mike (the same Mike that others are referencing probably) that this OS-4000LS is the same model as OS-4000CS except this version had foot rollers. They offered a price match for the upgraded version and I purchased on the spot. Mike has been v helpful in answering post-purchase inquires over email in a timely matter. Kev.

I bought this 10 days ago, and so far I am very impressed with it. I am 86 years old and have lots of aches and pains, especially in the lower back, and this chair relieves them all. Love it messaging my feet and legs as well.

We absolutely love these chairs! We decided that we had to have a his and hers set up for our new basement and they are a hit. The foot rollers are probably my favorite, oh and the deep tissue setting. They’re easy to operate and have a very nice appearance to boot.
One last thing I have to mention is the top notch service we received from massagechairdeals.com. I ordered the chairs on Tuesday a week before Thanksgiving and absolutely needed them by the next Wednesday as we were entertaining for Thanksgiving. He said it shouldn’t be a problem but with black Friday on the horizon etc. he couldn’t guarantee anything. So I proceeded with the order and I couldn’t believe when they arrived 3 days later!!! Very impressed highly recommend doing business with this company!
