Signature Design by Ashley 10" Mattress Box Spring with Metal Foundation - Full Size Bed Frame in Black | Durable Support for Back Pain Relief & Enhanced Sleep Comfort | Perfect for Guest Rooms, Dorms & Master Bedrooms

Was surprised that it was metal rods that needed to be put together with a cover over it. It was surprising but durable and looks and works great.easy to assemble and good valueEasy to put together BUT, instructions are poor...didn't notice the velcro on the bottom until after it was completed and that is necessary to "secure" the cover to the frame...needless to say I did not take it apart to move 2 pieces. Yet another case of pictures only for instructions...not a big issue for me but would be for others I am sure.All I can say is wow! The last box spring I owned was the “old fashioned” wood and fabric monster that gave you a hernia every time you moved it! You won’t regret buying this. We got it because we ordered a mattress that was supposed to not need a box spring with the platform bed we got as well. Wrong,lol. My husband and son put it together,it was fast and easy for them. (I don’t put things together)The fabric cover is very heavy duty and secures the frame to make it tight. And the bonus is that it’s light but STURDY! We got my son a very nice heavy mattress and and that box frame just looked at it and said”bring it!” Do it,you won’t regret it. :)RecomiendoGreat in every way. Easy assembly. Quick to assemble. Perfect fit. I order (2) of these. You need (2) Twin XL of these to go under my new KING size mattress (King mattress = 76"x80"). Very sturdy. No way that these are going to fall apart like some other reviews I have read. Possibly the people who said they fall apart are not putting them together correctly in the first place or using them on some uneven surface. All I know is that I love them and love the great SUPPORT they give us and the mattress. EXCELLENT product!It was super easy to assemble and very lightweight so easy to move around. It was all metal with a pull over cover. Definitely recommend!My son bought this and put on a wooden frame and the mattress sagged after 1 month. Would not recommend.
