Platform beds often make use of bunkie boards under the mattress. Ask wherever mattress are sold, or online. It's a solid platform that comes in various heights. I cover it with a matching fitted sheet.

Thank you, sushipup2, I didn't know of the existence of bunkie boards! Looks like they would add 1-3" of height which, depending on the bed and the mattress, might or might not be enough. I will add that to our arsenal of possibilities!

I’m in Canada and we have box springs available in regular 9” high or low profile in 5” high to place under a mattress so there must be something similar in the US that you could look into. It can make the bed quite high depending on the platform bed you choose, you simply need to choose the right platform bed that can accommodate the extra height of a box spring.

lisedv, thank you! Looks like there is such a thing as a low-profile box spring in the US - that sounds promising.

I don't know where you live nor your budget and style but Ikea has a sofa model with rolled arms, the Uppland, that is very comfortable with a seat height at 18 1/2 inches and a washable slipcover that can be practical depending on the use. Available in different sizes & models as well as different fabrics.

lisedv, there is only one IKEA in my state and it's a couple of hours away. Of course, I could purchase online. That looks very comfortable and practical, and I like the slipcover idea! Looking at the IKEA website, I see at least one model sofa that is taller, which could be a good choice. Thank you for the idea!

My elderly in-laws (85 and 90) live in our mother-in-law apartment. Some essentials for them are separate twin XL beds with electric head and foot adjustability, electric lift recliners, and dining chairs with arms to help them stand up. I would encourage you to have floor electrical outlets installed near your recliners.

ginatay124, we may eventually do that. It's the one thing that was discussed when we were designing the house that never made it into the plans, and we missed it until the house was finished. We're a little cautious at this point about drilling into the hardwood floors until we know for sure exactly where we want those outlets, so we'll probably get something we can work now (we're still "only" in our our 60s, and in good shape physically) and then in a few years install outlets and get electric recliners. The dining chairs with arms are a good thought. Thank you!

Aside from furnishings, how are the bathroom fixtures - toilet height & shower space? Chairs - don’t know what your budget is but I’d look at Ekornes Stressless recliners,

KW PNW Z8 We hired a design-build firm that is certified in aging-in-place, so those details about toilets, showers, etc are all taken care of. We have a bathroom vanity with a nifty front that will slide into the vanity opening up the space under the sink, should one of us be in a wheelchair, and the shower is curbless.

I've never heard of Ekornes Stressless recliners - I will check them (and my budget!) out! Thank you!

Olychick, thank you for the tips! I just looked up Room and Board, because I'd never heard of it. I really like their furniture! But, alas, the closest one is a 3.5 hour drive. Still, there may be a way... We also have the issue of bedding size - we have a quilt that we commissioned for an anniversary, and it's a bit longer than I'd like. So that is informing our bed height a bit, and I'll eventually have a step stool.
