Unlike many bean bags, the Omni’s main strength is versatility because the pillow like shape can be reformed into almost anything you desire. It is possible to even deform the Sumo to allow for arm rests on either side of the arms, which will be perfect for gaming sessions with the Xbox 360 or Playstation 3. Heck even my dog found it comfortable for a spot of relaxation after her dinner.
The polystyrene foam insides conform to your particular body shape but they never deform to a point where you would sink into the chair itself. It is possible that two average people with suitably normal sized bottoms would be able to fit into the Sumo Omni so there are plenty of ‘cuddling’ opportunities for that someone special. If your girlfriend happens to be Jennifer Lopez however then an additional purchase might be required...
Available colours:

Perhaps a ‘his’ and ‘her’ matching pink and blue? |

The nylon is rip proof and is resistant to staining and is easily washed down with soapy warm water. If you spill your drink or an ice cream all over it while watching your movies it is not a chore to get it back to brand new condition.
Objectively the Omni’s biggest downfall is also its strongest point, the sheer size of the monolithic bum rest. Storing a bean bag the size of a standard sofa which weighs 8 kg is not an easy proposition because you can not really just chuck it into a cupboard between gaming sessions. I would surmise that the majority of people buying one of these will have to keep them in full view in their room of choice and while they are quite attractive this may prove a breaking point for many people considering a purchase.
The Sumo Omni also comes with a guarantee but if you find it starts to deform excessively then you can buy bead refills direct from Sumo.
The Sumo is not a bargain price, but the quality of the unit reflects the cost which is £99 in the UK and $149 in the USA. You can buy directly from Sumo on their website and the shipping costs are included in the price which helps you to justify the cost to your significant other (or clan). Your ass will appreciate it, I know mine has.
