  • Mattress Platform 4"
Color: 4 Inch Size: King
I put this Mattress Platform together myself (female, in my 60's), for my 85 year old Mom - who is about to return home from rehab (after breaking her femur & having her arteficial knee replaced). Her bed was too high before - and this 4" Mattress Platform (box spring alternative) was the perfect solution. Easy to follow instructions & simple to build; it also seems very strong. Highly recommended. 👍🏼 ... show more

  • Surprisingly great!
Color: 4 Inch Size: King
The quality of this product is so much better than the price might indicate! It is definitely heavy duty and was easy to put together. The middle support bar keeps our heavy mattress from drooping. Highly recommend!

  • Does the job.
Color: 4 Inch Size: Queen
It works fine but the mattress slips around vs. a standard box spring because of the all steel construction.

  • It match my bed set dimensions
Color: 4 Inch Size: Queen

  • Easy to put together
Color: 4 Inch Size: Queen
I needed to switch out a 10 inch box spring to a 4 inch, so I order this one mainly because it came with a cover. It arrived quickly and took about 45 minutes to put together, it seems to be made very well, what took the longest was putting in the nuts a screws but that's to be expected. Very happy with it ... show more

  • Tough to put together for this 70 year old grandma but I did it.
Color: 4 Inch Size: Queen
I had to UTUBE on how to put it together, took a while and many frustrating breaks, had to walk away several times but I did get it together.
