I don’t recommend this sofa AT ALL. We got this for daily use and thought the sofa bed mechanism would be practical to have a proper double size bed for our guests. Unfortunately, the seating side wears out SO fast (within 3-4 months it was sinking) and there is already alignment issue when used as bed! Because of poorly constructed and sinking seat pillows, unfortunately it is also uncomfortable to sit on more than 20-30mins due to sinking and you almost feel the bottom wooden layer after some time..  Please bear in mind that we are often out and about and sit on this sofa max 15-20 hrs per week (and avg people weighing c. 65kg to 85kg). This sofa was only delivered on 4 Apr 2019 which means it is c. 5 months old or so. 
Don’t buy it.. Or get similar ones from elsewhere as they usually have better customer service or agree to come and check what’s wrong with the item! Won’t buy another piece from this retailer ever again..
