Question: Do I have to purchase a separate pump or does it come with a built in pump?
Document: Plugged in the air bed pump and all 3 separate sections were filled by 8 p.m. I had to deflate the back rest cushion and tuck it under the seat cushion at bed time because 'pulled out' it takes up up 8 ft of the 10 ft width. No big deal because the base and the seat cushion were more than roomy enough for me.I understood before purchase that inflatable beds and /or furniture will 'stretch' and feel as if air has leaked.
This product is so great for the price, and it came literally within three days which was amazing. Its very spacious, it sits three people when in sofa mode and turns into a queen size bed when opened out. The cup holders are very handy and it's lightweight. The only thing is that it did not come with a pump but you can easily purchase that in a store.
The sofa has three separate sections to inflate. The main section can't maintain pressure, and deflates as soon as you sit on it. I can't find a hole, anywhere, so I suspect that it's a defect. How can I know for sure? I wouldn't recommend it as a purchase.
I decided to purchase the Intex pull-out sofa for my new apartment since I had previously purchased the Intex Lounger and loved it. The sofa arrived quickly and inflated with no difficultly. Almost 2 months later it's still going strong as our regular living room sofa. The built in drink holders work perfectly and keep your beverage very stable even when others are mounting/dismounting the sofa. Despite the sectional nature of the pull-out bed I've had only positive feedback from the guests that have slept on it so far.
I rolled out the sofa, plugged in the pump, and began inflating. There are three separate parts that need inflated. The first is the 'base' of the couch- which includes the floor layer, back, and arm rests. Then there is the back cushion that needs inflated. And the butt cushion- the place you will sit. Once all three components are inflated, the couch looks AWESOME.
I would have given this 5 stars if it had a pump built in to the main section like the queen air mattress(also by Intex) had. On that note a pump of any type would have been appreciated. Thank goodness I had kept a battery operated pump. But after getting it blown up, it looks great and is comfortable, at least as a sofa. I haven't had a chance to sleep on it folded out.
This thing was the biggest piece of junk i have ever owned. It doesnt stay inflated longer than 4 or 5 hours. Then you have to pump it back up in different areas because they are not connected as one piece. It also does not have a built in pump like most of these products do no a days.
the sofabed did not come with the pump, it was not advertised properly so I had to buy it separately.
Is nice and I like it, just it did not come with a pump so I needed to buy my own pump but that's alright.
Love this temporary couch. I thought it might come with a portable air pump like other inflatable items I recently bought. Thank God I had one on hand. Love this item though and the fast shipping. Great seller!!! :)
