I doubt you're going to find that EXACT bench ... the website says they are custom made to order in Australia. For something 'similar', I would google image search 'tufted modern ottoman chrome"

I would recommend a higher bed whether ensemble or any style of base with top mattress or pillow top. I have had serious spinal injuries since 25 (I'm now 40) I would advise any bed reaching around 70cm in height regardless off style. There are a few things that I would advise, overall height around 70cm or a little more, most important to consider is comfort. Do not worry about aesthetics when choosing bed as your sleep is more important to your overall health. So if you can afford the more comfortable bed go for it. As for putting on sheets etc, the weight off mattresses is not really a big deal as it is your sleep comfort that is important. With pillow top mattress with a fitted sheet needing a 45cm fitted sheet are easy to find and purchase from same place bed is purchased. In Australia all bed sheet supplies are available for pillow top with 45cm drop fitted. Percale last longer and are around $100 per set and 1000 thread count. Spotlight have great sales and choices as well as Pillow Talk. I have found Adair's to be quite expensive in comparison but that is up to you to decide. I hope you have many a restful nights sleep. But do not worry about weight of mattress as you need your sleep to live healthy and it is an investment for around ten years so how it looks and weight of mattress should be last on list. Designers may disagree, but our bedrooms are normally our sanctuaries and it is rather easy to make any bed style work for you and decorate to your style.

It probably depends on where you live. If there are lots of families then i think the 4 beds would be the preference, 3 brms are a lot more common so often 4 commands a premium. An ensuite is always desirable but i would probably just look at converting the linen into another toilet. And create built in storage in all the beds

@oklouise Thank you so much. The measurement above shall be an accrurate one ( I measured myself not long ago :) But sadly we are in the middle of reno already. Walls knocked off and plan is as per I shared with you. We are struggle on the dinning / living area while we scratch our head where to put our TV but at the sametime the dinning table location makes sense.
