    FAQ

    I would like to perform a heating / cooling program where the temperature ramps from one set point to another over time. Are the PolyScience 20 Liter Integrated Heated Baths capable of this?

    That depends on the controller used. Only the Advanced Programmable and Performance Programmable controllers can be programmed to perform ramps.

     

    It is possible to have the circulation on without any temperature control being on?

    No. If the circulation is on, then a temperature setting must be selected.

    Updated after less then 3 months of owning!
    I have only had the chair a few hours now so this review is of first impression and details. I usually wait to do reviews but choose to on this one. Things I noticed that maybe important to others as information: If you are a tall person you may want to measure your height and etc. I am 5' 6" Tall 175lbs. and this chair is perfect size for me. it does have some room 20" max width from arm rest to arm rest. seat is 19" deep from back to front, Back Height from seat is 26" to top (Will be a little more height when sat on) but this being said the top of my head is just perfectly at the top of the head rest height. Putting it together is a breeze and anyone could put this together, Everything's Labeled to fit the instructions, packaged well. Took me about 10 minutes. Pros: Very Comfortable, Perfect size for me, Looks Great, Easy to put together if you follow the easy directions. No tools needed (Tool is included), Arm rests Height Perfect, Cons: The Back is only held together by the arm rests, This I find very odd but possibly normal to all chairs. If you rock the chair back and forth you can feel the back flexing (This I believe to be why others have claimed the chair squeaks and makes noise while tilting back). I am going to make a bracket that will attach the back to the bottom of the Seat to keep it secure and sturdy for the long haul. P.S update on the chair after less then 3 months of owning, although the chair is still comfortable but with a major Con. with normal daily use the fake leather on the arm rests has started to crack and peal. I will not be buying this chair again nor recommend to anyone.

    I really wanted to like this chair,
    it looks good, it is a nice size, and it starts out pretty comfortable. The vinyl seems pretty durable and I've not had the troubles others have noted with seams tearing or starting out faulty, mine have been near perfect. Assembly is easy, just 12 screws and you simply put them all in finger tight, then toque them down a bit at a time over about 3 passes to get them evenly tight while letting everything balance out as it goes. Much like changing a car tire. If you install one screw and tighten with all your might then move on to the next you'll have trouble with anything you try to assemble, including this chair. Assembly is rarely a problem for me, but the issue here is the padding. I weigh less than the weight limit but I'm tall and thin and my muscular bicyclist's butt is apparently too much for this chair's cushions. At 8 months, I gave up on blankets and pillows and Amazon politely replaced my first chair with zero fuss. Two months later I got a job telecommuting and the 2nd chair has gone totally flat in only another month. I really wanted to like this chair, but the padding just doesn't last. Update: I've been using an additional pad in the seat and though I'm not fond of the look, the price is right since I already paid for the chair. A couple days ago I leaned back and hear a "pop". The back is all floppy and so I take it apart looking for the problem. I tracked the problem to a metal bracket inside the upholstery. I had to cut the vinyl to reach the problem but found the bracket is a large well engineered solid steel plate with plenty of surface area to handle the stresses and the wood is top quality plywood with no voids. Amazon did an awesome job having this chair re-engineered and specified good materials, but their assemblers didn't bother to tighten the screws. No amount of engineering can fix lousy assembly work. Amazon is clearly trying here but they're being thwarted by their supply chain left and right. To be fair, the two chairs they have sent me collectively did last enough for the price I paid so I won't be asking for another replacement.

    Solid quality and comfortable
    Color: Light Grey, Color: Light Grey
    Wonderful quality chair, solid and sturdy, it was easy to put together, the directions were very clear and all the pieces fit together perfectly without issue. It is made of breathable material and I love that the arms flip up easily. You can raise it up or down and it has an adjustable headrest. It also has adjustable lumber support. It rolls easily and the color is the only reason I might return, I think I want a different one instead. The chair is comfortable for a petite person but equally comfortable for a tall person. We have both in our family and it is great for both. The armrests are comfortable and there is really nothing negative to say about this chair at all. Considering the quality, it is a great value for the money.

    Comfortable and Sturdy Office Chair
    Color: Black, Color: Black
    I’ve been very happy with this chair so far. The quality feels solid, and the materials look durable. The color matches the listing perfectly and fits nicely with my office setup. It’s very comfortable for long periods of sitting, with good support for my back and shoulders. Assembly was straightforward, and all the parts were included. The chair looks modern and professional, and the overall appearance exceeded my expectations. It feels stable and secure, even when reclining or moving around. The wheels roll smoothly, and the chair is easy to adjust for a comfortable fit. Overall, this is a well-made, comfortable, and attractive office chair that offers great value for the price.
