User questions & answers

Question:	I am over 6 feet tall will it be able to reach my head or is it shorter? just asking
Answer:	Spouse is over 6 ft tall, and he looks like a clown sitting in a child's chair. It's not a very big chair at all. The max weight capacity is 300 LBS, but honestly I'm half of that and after owning the chair just a few weeks it's already falling apart. Avoid it!
Question:	why does it smell and when does it go away
Answer:	That smell is not just from flame retardant. That smell comes from just about everything man made such as: the foam cushion, artificial leather, laminates, carpets and so on and so forth. The reason some new products do not have the smell is because the manufacturer has the good sense to let that thing air out in the factory for a few days before shipping it to retailers that immediately ship it to customers.
Question:	So the armrests aren't adjustable
Answer:	Not only are they not adjustable but are beyond crap... I've had mine a couple months and the arms are moving away from the body of the chair. I can litteraly pull them inward and it's only getting worse. I'm currently looking for a new one this is getting donated
Question:	But can you do this
Answer:	but can you play tuber simulator on this chair?! reeeeeeee
Question:	Does the mattress come with the frame
Answer:	No
Question:	are the Lurroy slats included
Answer:	No
Question:	Does this include the Center support beam and slatted bed base? Ikea has one without for $50 and with them for $99. Does not specify here
Answer:	No it does not include the slatted bed base.
Question:	Does it come with a mattress
Answer:	No bought super beauty rest in line for$200
Question:	Is there a way to stop these from moving around? They don’t stay in place for me and fall off constantly
Answer:	You can use self tapping screw from a couple point
Question:	What is the width of this slat combination
Answer:	These are the manufacturer dimensions :Length: 74 3/4 "Width: 52 3/4 "Height: 1 5/8 "Mattress length: 74 3/4 "Mattress width: 53 1/8 "Hope this helps!
Question:	will it fit an IKEA Beddinge bed frame? There are no plastic caps glued to my metal frame so how will theses slats work? What size frame is it for
Answer:	Fit perfectly.this is for full size. you should have a metal galvanize in ikea
Question:	How pronounced and firm is that curve? Would a pocket spring mattress not be advised? Also what is the distance between the slats
Answer:	I use it with spring mattress no problemDistance between slats looks like 1 inches
Question:	Will this work on a queen size bed
Answer:	I purchased this and used it on my Queen bed from IKEA after the original was damaged. (So, yes, confirmed.)
Question:	Does this go from top to bottom of the bed or crosswise
Answer:	Side to side..crosswise
Question:	Is there just a single beam, or does it came as a pack of three
Answer:	Mine came as a two piece beam
Question:	Does this beam only work with ikea beds
Answer:	It can be used on any bed if you can mount it at each end to your bed frame (headboard and footboard). It is adjustable for length so is very versatile. I used one to beef up my full size bed support so that I could throw out my box spring and use mattress only with a few wooden board cross supports. I got the two mounting brackets at my local IKEA for free just for asking for them at the customer service counter. Of course I bought my beam directly at the IKEA store and not online. It was much cheaper at IKEA, just check the IKEA website. Worth the trip.

User questions & answers

Question:	How wide is the diameter of the wheels, you have mentioned they are of shoulder width, how much is that? I mean, that cannot be a standard, is it
Answer:	Yes. The user manual shows the instructions. —— A4 Pitch Calibration —— A4 pitch calibration is an advanced function. The default and recommended setting is 440 Hz. A4, or A440, is a generally accepted tuning standard in most countries. However, the ZenTuner can adjust the A4 frequency anywhere from 430-450 Hz if necessary. Press button 2 (Mode) for 2 seconds while powered on, and the A4 display (B) will flash. Press the A4 pitch button 3 to adjust the A4 frequency, increasing by one on the display (B) each time you press. Once the display reads 450, the next press will display 430 and will increase again by continuing to press the button.
Question:	Contact Seller
Answer:	I think it will work on any instrument/object that emits a vibration and that it can clip to.
Question:	Will you be getting any pink back in stock? I waited too long to order
Answer:	I concur with Bruce Wood. The tuner in question works via vibration of the instrument being used. Since it works on electric and acoustic guitars, it should work just fine as long as you have someplace to clamp the tuner to.
Question:	No tracking given
Answer:	The Letters on the bottom are as follows. C=chromatic (any stringed), G= Guitar, V=Violin, B=Bass, U=Ukulele. I hope that helps.
