Pop up trundle

Well made and mattresses are great for the price. Just what we needed for visiting relatives.

Trundle bed

Pros: Great communication and customer service

Cons: Maybe look into a better, more reliable carrier

Overall the service was good. Also great quality beds and frames. Communication was great when a delivery issue presented. Instead of us having to continue to hunt for missing package, they were nice to send another right away.

Twin extra long trundle bed

Cons: None

This trundle bed is wonderful. It is of very quality construction. The trundle is twin size and the main bed is a twin extra long. It has no sides or a back which makes a king size bed accessible from each side when its turned 90 to the wall, perfect for guests and those over 6ft tall. There is a pin that locks the trundle in either the up or down positions. I also bought the insert that goes between the two firm mattresses to make one king size mattress. It is very comfortable and attractive.

Trundle with Pop-up

Pros: Super Sturdy

It was REALLY difficult to find a trundle bed with a pop-up. I have a home office and prefer a day bed option that looks nice in the room and provides flexibility for sleeping arrangements - a couple as well as grandkids. This was the set up I was looking for online and this was the only place I found exactly what I needed. A regular twin and mattress fits just right under the larger twin XL. It was easy to put together and is very sturdy.

XL trundle bed

Great xl trundle bed. Easy to put together and holds the mattress without it sliding. Love that the legs on the trundle pull out. No worries about the bed falling. Love the fact that its for an adult.

Submitted by Felicia on 01/17/2021 02:15:09 PM.

Questions and Answers

Q: Roll the trundle out but leave it in the down position" Can it roll out away from the bed or only next to the bed? So I can separate 2 young teens

A: Yes, each unit is completely free standing.

Submitted by Deb on 07/14/2022 05:17:21 PM.

Q: What do the bottom of the legs on the Twin XL portion of the set look like? I want to know if "carpet glide" discs can be attached to the bottom of the Twin XL portion of this set so that the bed can be easily moved on carpet. I know that the trundle is on wheels so that part is easy....

A: Yes, most carpet glides will work but if they are too high it may affect the height of the mattress and they will not be at the same level when in the up position.

Submitted by Lora on 07/21/2022 01:48:05 PM.

Q: Is it possible to order one of full set (SP16: twin xl bed with twin trundle) plus an additional matching twin xl bed frame only with no trundle? I need these for a room with two twin XL beds that can be pushed together to make a king, but with only one trundle underneath.

A: Yes, you can. Here is the link to order just the top bed https://foldingbed.net/Item/VC16BX09Xaz

Q: Can you order just the frame without the trundle. If so, how much?

A: Yes, you can. The current price is $250.00

Submitted by Cj on 09/04/2022 09:52:09 PM.

A: It is 400 lbs of distributed weight for each bed.

Submitted by Debbie on 10/12/2022 02:04:43 AM.

Q: What size mattresses are needed for this XL trundle bed?

A: The top mattress is a twin extra long 39x80" and the bottom is a regular twin size mattress.

Submitted by Sport on 10/17/2022 02:56:47 AM.

Q: Is this bed and trundle that states 400 pounds distributed weight capacity mean 200 pounds each bed? Or 400 pounds each bed?

A: It is 400 lbs distributed weight as you would lay on the bed. Not in any one particular spot.

Q: can only the primary bed be purchased without the trundle? thank you!

A: Yes, please contact us for the link to it.

Submitted by AFB on 10/27/2022 05:28:26 PM.

Q: I'd like to put these mattresses together to make a king size guest bed, which is what the picture seems to show. But since the bottom frame only allows for a regular twin mattress rather than an extra long, can this actually be done?

A: Yes, you can put it together to make a king size bed but the bottom mattress will be about 5" shorter.

Submitted by Lynn on 11/27/2022 08:35:22 PM.

Q: How does the bed connector thing work with a twin XL and the twin trundle?

A: If you want to connect them together then you need to get the bed doubler.
