I took my family on a round the world trip in April 2010 and few on Singapore Airlines all the way in Business Class. Flew on the A330 from Perth to Singapore which was not bad, however found the seats a little small and not as comfortable considering it was a late flight and would have liked to get some sleep. From Singapore to Tokyo we flew on the A380, which we have done a few time before and was a good as always, lots of room and the bed was nice and flat and easy to make, had seats in first section and up stairs which in my opinion is the best location. Tokyo to LA on B747-400, older aircraft and found the seats comfortable, but not as good as A380. London to Singapore on the A380 and again had same seats as before and it was excellent.

Singapore to Cairo they use the older configuration 777-200's. The seating should really be classed as premium economy, as it does not meet the standards you expect of SIA. On a 10 hour+ flight, seat does not fully recline, or provide a restful position. Beware first row of seats as the light above at the doorway to galley is on all night.

Singapore to Dubai is an overnight flight but the seat is terrible. It's doesn't go to anything near flat, and is hard and uncomfortable. I couldn't sleep. Singapore Airlines should be embarrassed to call this a Business Class seat.

Singapore to Rome, Italy on the older 777-200ER. Very disappointed with the flat but slightly inclined seats, armrest not lowered during sleeping position. Luckily, we caught some sleep with the aid of a pill, otherwise, it would be hard to sleep with the very tight space constraint. But on the return flight on the same aircraft model, the armrest can be lowered, affording a better night's sleep. Its a shame as even Thai Airway's new Shell seats are better than SIA's old shell seats. But then, when we fly to Milan on SIA's 777-300ER, their new Business class fully flat beds are overly spacious and luxurious, thumbs up for those!

First time on A380 in new SQ business class seat. Seat very (too?) wide but limited adjustment options and reclining seat means legroom quite constricted by standards of today's business class. Best option for legroom is to sit diagonally which is not that comfortable. Good storage space. Bed comfortable though may be a little firm for some.

Although the seats were large and laid down flat, while in the sitting position the cushions had little to no give. However, being that the seats are so wide and leg room so vast this almost made up for the hard seats - almost. Service is wonderful and you will want for nothing, except a cushion to ease the pain.

An older 777-200 (not 200ER) with older blue angled lie-flat business class seats. The seat is motorized and can be made flat - but not completely horizontal. The seat configuration is 2-2-2 so window seats don't have direct aisle access. Best to get one of the middle two seats, otherwise you may have to climb over someone to get to the bathroom, or you have someone climbing over you to get to the bathroom.

LAX-Tokyo Singapore Airline is still using the older airplane for this route. The seat doesn't fully recline. My husband was 6'4" and he found the seat uncomfortable when it fully extend due to the limited leg room - if you are shorter than 6', the seat is not that bad. I still find it hard to sleep in these type of seats, seat width is a lot narrower than newer airplanes.

I read a lot about the seats being too wide to be comfortable but loved the extra room. A380 was brilliant, staff were attentive and found the seat easy to change into a bed for sleeping.

My husband and I were on the upper deck on row 14 in the middle. Very wide seats, we're both over 6 feet and had plenty of space. Putting up the bed was a bit difficult but the stewardess came to explain how it worked.

This Ultra-wide seat is one to polarise opinions. You either love it or hate it. Seat adjustments are more limited compared to the older seats. Sideways, legs under, into the extension, etc. Sleeping arrangements suit me, the flatness and width of the bed is perfect. The seat takes a bit of getting used to, but once you've figured it out, it's very nice.

I was not impressed with this seat. It does lay totally flat and provides a good sleep. But in the upright position this seat is very disappointing. This very wide seat can make a grown man feel small. Sounds appealing but in fact you get lost in this seat. Armrests are too far apart and I was never able to adjust the seat to get comfortable. Very little lumbar support and I didn't see any way to inflate lumbar like some airline seats offer. I was served a snack while the seat was flat for sleeping and the flight attendant said that I could just sit up without putting the seat upright. This was very uncomfortable as there is not really any way to comfortably lean back once the seat is converted for sleeping. One positive about the Singapore seating area is there is plenty of space to stow a laptop, reading materials, etc. I sat in row 14 and there is a shelf that folds down that provides great storage. Not sure whether this was unique to the 14th row as these are configured a little differently. I think Singapore could have done a better job on this seat design.
